Radiography and ultrasonography are tools for diagnosing disease and evaluating the anatomical architecture of parts of the body non-invasively. As the rabbit is becoming a more important food animal, to achieve improved breeding of these animals, the best of the species form a breeding stock and will usually depend on breeding soundness which may be evaluated by assessment of the male reproductive organs by these tools. Four male intact rabbits weighing between 1.2 to 1.5 kg were acquired and acclimatized for 2 weeks. Dorsoventral views of the testes were acquired using a digital radiographic machine and a 5 MHz portable ultrasound scanner was used to acquire images of the testes in longitudinal, sagittal and transverse planes. Radiographic images acquired revealed soft tissue images of the testes in all rabbits. The testes lie in individual scrotal sacs sides on both sides of the midline at the level of the caudal vertebrae and thus are superimposed by caudal vertebrae and the caudal limits of the pelvic girdle. The ultrasonographic images revealed mostly homogenously hypoechogenic testes and a hyperechogenic mediastinum testis. The dorsal and ventral poles of the testes were heterogeneously hypoechogenic and correspond to the epididymis and spermatic cord. The rabbit is unique in the ability to retract the testes particularly when stressed and so careful and stressless handling during the procedures is of paramount importance. The imaging of rabbit testes can be safely done using both imaging methods but ultrasonography is a better method of assessment and evaluation of soundness for breeding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breeding%20soundness" title="breeding soundness">breeding soundness</a>, <a href="https://publications.waset.org/abstracts/search?q=rabbit" title=" rabbit"> rabbit</a>, <a href="https://publications.waset.org/abstracts/search?q=radiography" title=" radiography"> radiography</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonography" title=" ultrasonography"> ultrasonography</a> </p> <a href="https://publications.waset.org/abstracts/105470/assessment-of-breeding-soundness-by-comparative-radiography-and-ultrasonography-of-rabbit-testes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105470.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Study of Effects of Hydro-Alcoholic Extract of Asparagus Root (Asparagus officinalis) Ontestes Spermyogenesis Index of Laboratory Mouse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Karimi">Hamid Karimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Naegar%20Mahdavi"> Naegar Mahdavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Tayefi%20Nasrabadi"> Hossein Tayefi Nasrabadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spermatozoids production rate and its quality are more important factors in the diagnosis of infertility. Also, spematozids activity have a more important role in fertilization. Some medicinal plants as Asparagus(Asparagus officinalis) has many antioxidant component. Therefore, They can affect testes tissue to production more and high-quality spermatozoids. In this survey, Asparagus root extract is studied on spermatogenesis index in the laboratory mouse testes. Hydro-alcoholic extract of asparagus root is prepared and examined on four group of the mature male mouse. Blank group without extract, group 1,100ml/kg dose, group 2, 200 ml/kg dose and group 3, 300ml/kg dose. Then, mice are euthanized, and testes are removed. Testes are weighted, and paraffinized blocks are prepared. TDI(Tubular Differentiation Index) and SPI(Spermiation Index) are studied on histological sections by light microscope. This study results were showed that TDI and SPI in treatments groups with 200 and 300 ml/kg dose had significant enhancement (P<0.05). Consequently, Extract of Asparagus root can enhance spermatozoid production and, therefore, cause improve fertility in male laboratory mice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=histology" title="histology">histology</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoid" title=" spermatozoid"> spermatozoid</a>, <a href="https://publications.waset.org/abstracts/search?q=ASP%20%5Baragus" title=" ASP [aragus"> ASP [aragus</a>, <a href="https://publications.waset.org/abstracts/search?q=testes" title=" testes"> testes</a> </p> <a href="https://publications.waset.org/abstracts/142815/study-of-effects-of-hydro-alcoholic-extract-of-asparagus-root-asparagus-officinalis-ontestes-spermyogenesis-index-of-laboratory-mouse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142815.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Therapeutic Effect of Diisopropyldithiocarbamate Sodium Salt Against Diclofenac Induced Testicular Damage in Male Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tella%20Toluwani">Tella Toluwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Adegbegi%20Ademuyiwa"> Adegbegi Ademuyiwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Musei%20Chiedu"> Musei Chiedu</a>, <a href="https://publications.waset.org/abstracts/search?q=Adekunle%20Odola"> Adekunle Odola</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayangbenro%20Ayansina"> Ayangbenro Ayansina</a>, <a href="https://publications.waset.org/abstracts/search?q=Adaramoye%20Oluwatosin"> Adaramoye Oluwatosin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dithiocarbamates are very useful biological agents with antioxidant properties. Diclofenac (DIC) is a non-steroidal analgesic, anti-inflammatory, and antipyretic agent. The use of diclofenac has been linked with reproductive toxicity/damage. The purpose of this study is (i) To investigate the therapeutic potential of diisopropyldithiocarbamate sodium salt (Na(i-Pr鈧俤tc)) and vitamin E (VIT E) against diclofenac induced toxicity in the testes of male Wistar rats. (ii) To investigate the effect of (Na(i-Pr鈧俤tc)) and vitamin E on ameliorating damage done to the testes through histological analysis of the testes. Thirty-six (36) male Wistar rats were used for the experiment, they were divided into six (6) groups, the animals in group 1 served as control, animals in groups 2, 3, 4, 5 and 6 received DIC only, DIC and (Na(i-Pr鈧俤tc)), DIC and VIT E, (Na(i-Pr鈧俤tc) only and VIT E only respectively. A single dose of 100 mg/kg body weight of DIC was administered to male Wistar rats, while 30 mg/kg body weight of (Na(i-Pr鈧俤tc)) was used to treat both normal and DIC treated animals, control animals were treated with the vehicle, after 24 hrs of treatment the animals were euthanized and the testes were removed for analysis. The treatment of rats with Na(i-Pr鈧俤tc) significantly restored catalase (CAT) activity depressed by diclofenac. (Na(i-Pr鈧俤tc)) also restored glutathione levels reduced by DIC treatment and this was also accompanied by reduced lipid peroxidation (LPO) level. VIT E significantly restored superoxide dismutase (SOD) activity when compared with DIC only treated animals. Photomicrographs of testes from (Na(i-Pr鈧俤tc)) treated rats showed seminiferous epithelium with no lesions. We conclude that (Na(i-Pr鈧俤tc)) has an antioxidant effect, which might be related to the dose and duration of administration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diisopropyldithiocarbamate%20sodium%20salt" title="diisopropyldithiocarbamate sodium salt">diisopropyldithiocarbamate sodium salt</a>, <a href="https://publications.waset.org/abstracts/search?q=diclofenac" title=" diclofenac"> diclofenac</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a>, <a href="https://publications.waset.org/abstracts/search?q=testes" title=" testes"> testes</a> </p> <a href="https://publications.waset.org/abstracts/140082/therapeutic-effect-of-diisopropyldithiocarbamate-sodium-salt-against-diclofenac-induced-testicular-damage-in-male-wistar-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140082.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Gonadotoxic and Cytotoxic Effect of Induced Obesity via Monosodium Glutamate on Mus musculus Testis Cytoarchitecture and Sperm Parameter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Nur%20Hilwani">I.

Monosodium glutamate (MSG) has been widely used as food additive, flavour enhancer and included in vaccines. This study focuses in determining the gonadotoxic and cytotoxic effect of MSG on selected sperm parameters such as sperm viability, sperm membrane integrity and testes cytoarchitecture of male mice via histological examination to determine its effect on spermatogenesis. Twenty-four Mus musculus were randomly divided into 4 groups and given intraperitoneal injections (IP) daily for 14 days of different MSG concentrations at 250, 500 and 1000mg/kg MSG to body weight to induce obesity. Saline was given to control group. Mice were sacrificed and analysis revealed abnormalities in values for sperm parameters and damages to testes cytoarchitecture of male mice. The results recorded decreased viability (p<0.05) and integrity of sperm membrane (p>0.05) with degenerative structures in seminiferous tubule of testes. The results indicated various implications of MSG on male mice reproductive system which has consequences in fertility potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sperm%20parameter" title="sperm parameter">sperm parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=testes%20histology" title=" testes histology"> testes histology</a>, <a href="https://publications.waset.org/abstracts/search?q=sperm%20viability" title=" sperm viability"> sperm viability</a>, <a href="https://publications.waset.org/abstracts/search?q=sperm%20membrane%20integrity" title=" sperm membrane integrity"> sperm membrane integrity</a> </p> <a href="https://publications.waset.org/abstracts/13066/gonadotoxic-and-cytotoxic-effect-of-induced-obesity-via-monosodium-glutamate-on-mus-musculus-testis-cytoarchitecture-and-sperm-parameter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13066.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Effect of Bilateral and Unilateral Castration on Feed Utilization and Carcass Characteristics of Growers Rabbit (Orytolagus cunniculus)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20Dikko">A.

Many theories attempt to explain the failure of the testes to migrate to their correct location. While the age at presentation can vary; most cases present in early adolescents or late adulthood. It is often an incidental discovery made during an operative intervention, most commonly during hernia exploration. It can be isolated or present with a plethora of anomalies. We present the case of a 2-year-old male with transverse testicular ectopia who presented with vague abdominal pain. He was managed successfully with the Modified Ombredanne procedure and good outcome 6 months after the procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptorchidism" title="cryptorchidism">cryptorchidism</a>, <a href="https://publications.waset.org/abstracts/search?q=persistent%20Mullerian%20duct%20syndrome" title=" persistent Mullerian duct syndrome"> persistent Mullerian duct syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=transverse%20testicular%20ectopia" title=" transverse testicular ectopia"> transverse testicular ectopia</a>, <a href="https://publications.waset.org/abstracts/search?q=testicular%20mal-descent" title=" testicular mal-descent"> testicular mal-descent</a> </p> <a href="https://publications.waset.org/abstracts/141125/transverse-testicular-ectopia-a-case-report-with-review-of-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141125.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Effects of Garlic (Allium sativum) Juice on Semen Oxidation in Male Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Ghiasi%20Ghalehkandi">Jamshid Ghiasi Ghalehkandi</a>, <a href="https://publications.waset.org/abstracts/search?q=Naser%20Maheri%20Sis"> Naser Maheri Sis</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Ebrahimnezhad"> Yahya Ebrahimnezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Hassanpour"> Shahin Hassanpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of present study was to examine the effects of fresh garlic juice on semen malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and total antioxidant status (TAS) in male rats.

In group 2, rats were gavaged with 60 mg/kg garlic juice. In group 3, rats were offered 120 mg/kg garlic juice. Animals received treatments orally and ad libitum access to chow pellets and fresh water. After 4 weeks, animals were killed, testes were taken out and semen samples were used to determine MDA, SOD, GPx and TAS activity. According to the results, garlic juice (120 mg/kg) significantly declined semen MDA activity compared to control group (P<0.05).

DNA sequencing of the AR gene detected a missense mutation C.1715A > G (p. Y572C) in exon 2 which is already known to cause Complete androgen insensitivity syndrome (CAIS). We further studied the effects of this mutation on the testicular histopathology of the patient. No spermatocytes were seen in the surface spreading of testicular tissues while H&E staining showed that seminiferous tubules predominantly have only Sertoli cells. To confirm this meiotic failure is likely due to the current AR mutation we performed mRNA expression of genes associated with AR pathway, expression and location of the associated proteins in testicular tissues. Western blot and real-time PCR data showed that the patient had high levels of expression of AMH, SOX9, and INNB in testis. Tubules were stained with SOX9 and AMH which revealed Sertoli cell maturation arrest. Therefore, we suggest that AR mutation enhances AMH expression which ultimately leads to failure in the maturation of Sertoli cells and failure in spermatogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=androgen%20receptor" title="androgen receptor">androgen receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatogenesis" title=" spermatogenesis"> spermatogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=infertility" title=" infertility"> infertility</a>, <a href="https://publications.waset.org/abstracts/search?q=Sertoli%20cell%20only%20syndrome" title=" Sertoli cell only syndrome"> Sertoli cell only syndrome</a> </p> <a href="https://publications.waset.org/abstracts/90798/the-effects-of-androgen-receptor-mutation-on-cryptorchid-testes-in-46-xy-female" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90798.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Protective Effects of Vitamin C and Vitamin E on Experimentally Induced Testicular Torsion and Detorsion in Rat Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anu%20Vinod%20Ranade">Anu Vinod Ranade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: To evaluate and compare the effects of Vitamin C and Vitamin E on experimentally induced testicular torsion and detorsion in rats. Methods: Forty Male Wistar Albino rats were divided into five groups. Animals in the Group I underwent Sham operation, Group II consisted of animals that were subjected to torsion for three hours followed by detorsion for 24 hours without any treatment. While Group III, IV and V were orally pretreated with Vitamin C (40mg/kg.bw), vitamin E (100mg/kg.bw) and a combination of Vitamin C and vitamin E respectively for a period of 30 days. The testes of the experimental groups were manually rotated to 720掳 clockwise for three hours and counter rotated for 24 hours to induce ischemia and reperfusion. Sequential biopsies were performed and the testes were collected at the end of 24 hours of detrosion for morphological evaluation. Result: There was a significant decrease in the standard tubular diameter and the epithelial height of the seminiferous tubules in the untreated group when compared to Sham controls. The standard tubular diameter and seminiferous epithelial height showed near normal values when animals were pretreated with Vitamin C and Vitamin E individually or in combination. Conclusion: The results showed that pretreatment of with antioxidants vitamin E and vitamin C when administered prior to testicular torsion in rats significantly reduced the torsion and detorsion induced histopathlogical injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vitamin%20C" title="vitamin C">vitamin C</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20tubular%20diameter" title=" standard tubular diameter"> standard tubular diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20epithelial%20height" title=" standard epithelial height"> standard epithelial height</a>, <a href="https://publications.waset.org/abstracts/search?q=testicular%20torsion" title=" testicular torsion"> testicular torsion</a> </p> <a href="https://publications.waset.org/abstracts/29446/protective-effects-of-vitamin-c-and-vitamin-e-on-experimentally-induced-testicular-torsion-and-detorsion-in-rat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Assessment of Reproductive Toxicity of Diazinon Pesticide in Male Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Alfaifi">Mohammad Alfaifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organophosphates are among the most widely used synthetic insect pesticides. The widespread use of organophosphates has stimulated research into the possible existence of effects related with their reproductive toxic activity. The present study aimed to assess the effects of diazinon (DIZ) on male reproductive system. DIZ at the dose levels of 1.5, 3.0 and 9.0 mg/kg b. wt./day was administered orally to male rats of Wistar strain for 30 days to evaluate the toxic alterations in testicular histology, biochemistry, sperm dynamics, and testosterone levels. The body weight of animals did not show any significant changes, however, a significant reduction was observed in testes weight. DIZ also brought about marked reduction in epididymal and testicular sperm counts in exposed males and a decrease in serum testosterone concentration. Histopathological examination of testes showed mild to severe degenerative changes in seminiferous tubules at various dose levels. Fertility test showed 79% negative results. All these toxic effects are moderate at low doses and become severe at higher dose levels. From the results of the present study it is concluded that DIZ induces severe testicular damage and results in reduction in sperm count and thus affect fertility.

The formation of synthesized nanoparticles was characterized by UV–visible analysis (UV–vis), Fourier transform infra-red (FT-IR), Transmission electron microscopy (TEM), Scanning electron microscope (SEM). TEM analysis showed particles size in the range of 20-30 nm. For this study, Swiss albino mice were selected from inbred colony and were divided into 4 groups: group I- control (irradiated-6 Gy), group II- normal (vehicle treated), group III- plant extract alone and group IV- CB-AgNPs (dose of 50 mg/kg body wt./day) administered orally for 7 consecutive days before irradiation to serve as experimental. CB-AgNPs pretreatment rendered significant increase in body weight and testes weight at various post irradiation intervals in comparison to irradiated group. Supplementation of CB-AgNPs reversed the adverse effects of gamma radiation on biochemical parameters as it notably ameliorated the elevation in lipid peroxidation and decline in glutathione concentration in testes. These observations indicate the radio-protective potential of CB-AgNPs in testicular constituents against gamma irradiation in mice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chlorophytum%20borivillianum" title="Chlorophytum borivillianum">Chlorophytum borivillianum</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=radioprotective" title=" radioprotective"> radioprotective</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/82691/ameliorating-effects-of-silver-nanoparticles-synthesized-using-chlorophytum-borivillianum-against-gamma-radiation-induced-oxidative-stress-in-testis-of-swiss-albino-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Co-Culture of Neonate Mouse Spermatogonial Stem Cells with Sertoli Cells: Inductive Role of Melatonin following Transplantation: Adult Azoospermia Mouse Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Abbasi">Mehdi Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadan%20Navid"> Shadan Navid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Pourahmadi"> Mohammad Pourahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Majidi%20Zolbin"> M.

Melatonin as an antioxidant plays a vital role in the development of SSCs in vitro. This study aimed to investigate evaluation of sertoli cells and melatonin simultaneously on SSC proliferation following transplantation to testis of adult mouse busulfan-treated azoospermia model. SSCs and sertoli cells were isolated from the testes of three to six-day old male mice.To determine the purity, Flow cytometry technique using PLZF antibody were evaluated. Isolated testicular cells were cultured in 伪MEM medium in the absence (control group) or presence (experimental group) of sertoli cells and melatonin extract for 2 weeks. We then transplanted SSCs by injection into the azoospermia mice model. Higher viability, proliferation, and Id4, Plzf, expression were observed in the presence of simultaneous sertoli cells and melatonin in vitro. Moreover, immunocytochemistry results showed higher Oct4 expression in this group. Eight weeks after transplantation, injected cells were localized at the base of seminiferous tubules in the recipient testes. The number of spermatogonia and the weight of testis were higher in the experimental group relative to control group. The results of our study suggest that this new protocol can increase the transplantation of these cells can be useful in the treatment of male infertility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colonization" title="colonization">colonization</a>, <a href="https://publications.waset.org/abstracts/search?q=melatonin" title=" melatonin"> melatonin</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatogonial%20stem%20cell" title=" spermatogonial stem cell"> spermatogonial stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=transplantation" title=" transplantation"> transplantation</a> </p> <a href="https://publications.waset.org/abstracts/84259/co-culture-of-neonate-mouse-spermatogonial-stem-cells-with-sertoli-cells-inductive-role-of-melatonin-following-transplantation-adult-azoospermia-mouse-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84259.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Morphometric Parameters and Evaluation of Persian Fallow Deer Semen in Dashenaz Refuge in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrang%20Ekrami">Behrang Ekrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Tamadon"> Amin Tamadon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persian fallow deer (Dama dama mesopotamica) is belonging to the family Cervidae and is only found in a few protected areas in the northwest, north, and southwest of Iran.

Seven experimental groups of adult male rats were formulated as follows: A) Controls + NS, B) Control+ vehicle (saline solution of hydroxypropyl cyclodextrin), C) RES treated, D) CdCl2 +NS, E) CdCl2+ vehicle, F) RES followed by CdCl2 and M) CdCl2 followed by RES. At the end of the protocol, serum levels of FSH, LH, and testosterone were measured in all groups. Testicular levels of TBARS and Super Oxide Dismutase (SOD) activity were also measured. Epidydidimal semen analysis was performed and testicular expression of Bcl-2, p53 and Bax were assessed by RT-PCR. Also, histopathological changes of testes were examined microscopically and described. Pre and Post administration of RES in cadmium chloride-intoxicated rats improved semen parameters including count, motility, daily sperm production and morphology, increased serum concentrations of gonadotropins and testosterone, decreased testicular lipid peroxidation and increased SOD activity. Not only RES attenuated cadmium chloride induced testicular histopathology but was also able to protect against the onset of cadmium chloride testicular toxicity. Cadmium chloride downregulated the anti-apoptotic gene Bcl2 and upregulated the expression of both pro-apoptotic genes p53 and Bax. Resveratrol protected from and partially reversed cadmium chloride testicular via upregulation of Bcl2 and down regulation of p53 and Bax gene expression. Antioxidant activity of RES protects against cadmium chloride testicular toxicity and partially reverses its effect via upregulation of BCl2 and downregulation of p53 and Bax expression. These findings have far reaching implications on subfertility and impotency frequently seen in hypertensive as well as metabolic syndrome patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resveratrol" title="resveratrol">resveratrol</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium" title=" cadmium"> cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=infertility" title=" infertility"> infertility</a>, <a href="https://publications.waset.org/abstracts/search?q=sperm" title=" sperm"> sperm</a>, <a href="https://publications.waset.org/abstracts/search?q=testis" title=" testis"> testis</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndrome" title=" metabolic syndrome"> metabolic syndrome</a> </p> <a href="https://publications.waset.org/abstracts/24438/reversal-of-testicular-damage-and-subfertility-by-resveratrol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24438.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">535</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Morphometric Parametersand Evaluation of Male Persian Fallow Deer Semen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrang%20Ekrami">Behrang Ekrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Tamadon"> Amin Tamadon</a>, <a href="https://publications.waset.org/abstracts/search?q=Iman%20Razeghian%20Jahromi"> Iman Razeghian Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Darioush%20Moghadas"> Darioush Moghadas</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ghahremani-Seno"> Mehdi Ghahremani-Seno</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Ghaderi-Zefrehei"> Mostafa Ghaderi-Zefrehei</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Sodagar%20Amiri"> Ahmad Sodagar Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Taheri%20Reza"> Taheri Reza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persian fallow deer (Dama dama mesopotamica) is belonging to the family Cervidae and is only found in a few protected areas in the northwest, north, and southwest of Iran.

It was concluded that TQ may represent a potential candidate to protect against arsenic-induced testicular injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thymoquinone" title="thymoquinone">thymoquinone</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic" title=" arsenic"> arsenic</a>, <a href="https://publications.waset.org/abstracts/search?q=testes" title=" testes"> testes</a>, <a href="https://publications.waset.org/abstracts/search?q=rats" title=" rats"> rats</a> </p> <a href="https://publications.waset.org/abstracts/6289/protective-effect-of-thymoquinone-against-arsenic-induced-testicular-toxicity-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6289.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Contributory Antioxidant Role of Testosterone and Oxidative Stress Biomarkers in Males Exposed to Mixed Chemicals in an Automobile Repair Community</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saheed%20A.%20Adekola">Saheed A.

It plays an important role in the development of testes and prostate and has a range of biological actions. There is evidence that exposure to mixed chemicals in the workplace leads to the generation of free radicals and inadequate antioxidants leading to oxidative stress, which may serve as an early indicator of a pathophysiologic state. Based on findings, testosterone shows direct antioxidant effects by increasing the activities of antioxidant enzymes like glutathione peroxidase, thus indirectly contributing to antioxidant capacity. Objective: To evaluate the antioxidant role of testosterone as well as the relationship between testosterone and oxidative stress biomarkers in males exposed to mixed chemicals in the automobile repair community. Methods: The study included 43 participants aged 22- 60years exposed to mixed chemicals (EMC) from the automobile repair community. Forty (40) apparently healthy, unexposed, age-matched controls were recruited after informed consent. Demographic, sexual and anthropometric characteristics were obtained from pre-test structured questionnaires using standard methods. Blood samples (10mls) were collected from each subject into plain bottles and sera obtained were used for biochemical analyses. Serum levels of testosterone and luteinizing hormone (LH) were determined by enzyme immunoassay method, EIA (Immunometrics UK.LTD). Levels of total antioxidant capacity (TAC), total plasma peroxide (TPP), Malondialdehyde (MDA), hydrogen peroxide (H2O2), glutathione peroxide (GPX), superoxide dismutase (SOD), glutathione-S-transferase (GST), and reduced glutathione (GSH) were determined using spectrophotometric methods respectively. Results obtained were analyzed using the Student鈥檚 t-test and Chi-square test for quantitative variables and qualitative variables respectively. Multiple regression was used to find associations and relationships between the variables. Results: Significant higher concentrations of TPP, MDA, OSI, H2O2 and GST were observed in EMC compared with controls (p < 0.001). Within EMC, significantly higher levels of testosterone, LH and TAC were observed in eugonadic when compared with hypogonadic participants (p < 0.001). Diastolic blood pressure, waist circumference, waist height ratio and waist hip ratio were significantly higher in participants EMC compared with the controls. Sexual history and dietary intake showed that the controls had normal erection during sex and took more vegetables in their diet which may therefore be beneficial. Conclusion: The significantly increased levels of total antioxidant capacity in males exposed to mixed chemicals despite their exposure may probably reflect the contributory antioxidant role testosterone that prevents oxidative stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mixed%20chemicals" title="mixed chemicals">mixed chemicals</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=hypogonadism%20testosterone" title=" hypogonadism testosterone"> hypogonadism testosterone</a> </p> <a href="https://publications.waset.org/abstracts/92952/contributory-antioxidant-role-of-testosterone-and-oxidative-stress-biomarkers-in-males-exposed-to-mixed-chemicals-in-an-automobile-repair-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92952.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Antioxidants Effects on Sperm Parameter in Varicocelized Male Rat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Abbasi">Mehdi Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoumeh%20Majidi%20Zolbin"> Masoumeh Majidi Zolbin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Varicocele is one of the common causes of infertility in 30-50% of married men which occurs within the spermatic cord. It can be considered as an abnormal dilatation and stasis of veins of the pampiniform plexus that drain the testis. It occurs in 15-20% of the male population. Inducible nitric oxide synthase (NOS) activity has been frequently reported in varicose veins. Several studies have considered the relationship between varicocele and semen NO concentrations. NOS isoforms have been shown to regulate a number of functions, e.g., sperm motility and maturation and germ cell apoptosis in the testes. In adult patients with varicocele, the amount of NO levels in the varicose veins are 25 times higher than in serum of peripheral veins. The aim of this study was to review the effect of different antioxidant that we applied so far on sperm parameters as well as sperm DNA fragmentation. The findings of this study suggest that antioxidants improve sperm parameters which are associated with infertility in varicocelized rats, and treatment can reduce damage to sperm DNA and increase the chance of fertility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a>, <a href="https://publications.waset.org/abstracts/search?q=sperm%20parameter" title=" sperm parameter"> sperm parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=varicocele" title=" varicocele"> varicocele</a> </p> <a href="https://publications.waset.org/abstracts/84230/antioxidants-effects-on-sperm-parameter-in-varicocelized-male-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Effect of Chemical Treatment on Mechanical Properties of KENAF Fiber Reinforced Unsaturated Polyester Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20Abdullahi">S.

The cured composites were subjected to various mechanical testes, such as hardness test, impact test and tensile strength test. The results obtained indicated an increase in all the parameters tested with the fiber treatment. This is because the lignin, hemi-celluloses, pectin and other impurities were removed during alkaline treatment (i.e mercerization).

RES (10 mg/kg/day) was given for 8 days orally and MTX (20 mg/kg i.p.) was given at day 4 of experiment, with or without RES in rats. MTX decreased serum testosterone, induced histopathological testicular damage, increased testicular tumor necrosis factor-伪 level and expression of nuclear factor-魏B and cyclooxygenase-2. In MTX/RES group, significant reversal of these parameters was noticed, compared to MTX group. Testicular expression of multidrug resistance protein (Mrp) 3 was three- and five-folds higher in RES- and MTX/RES-treated groups, respectively. In vitro, using prostate cancer cells, each of MTX and RES alone induced cytotoxicity with IC50 0.18 卤 0.08 and 20.5 卤 3.6 碌M, respectively. RES also significantly enhanced cytotoxicity of MTX. In conclusion, RES appears to have dual beneficial effect, as it promotes MTX tumor cytotoxicity, while protecting the testes, probably via up-regulation of testicular Mrp3 as a novel mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resveratrol" title="resveratrol">resveratrol</a>, <a href="https://publications.waset.org/abstracts/search?q=methotrexate" title=" methotrexate"> methotrexate</a>, <a href="https://publications.waset.org/abstracts/search?q=multidrug%20resistance%20protein%203" title=" multidrug resistance protein 3"> multidrug resistance protein 3</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20necrosis%20factor-%CE%B1" title=" tumor necrosis factor-伪"> tumor necrosis factor-伪</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20factor-%CE%BAB" title=" nuclear factor-魏B"> nuclear factor-魏B</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclooxygenase-2" title=" cyclooxygenase-2"> cyclooxygenase-2</a> </p> <a href="https://publications.waset.org/abstracts/17378/involvement-of-multi-drug-resistance-protein-mrp-3-in-resveratrol-protection-against-methotrexate-induced-testicular-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17378.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> The Effect of 尾-Cryptoxanthin on Testicular Ischemia-Reperfusion Injury in a Rat Model: Evidence from Testicular Histology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kianoush%20Mohammadnejad">Kianoush Mohammadnejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahim%20Mohammadi"> Rahim Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Soleimanzadeh"> Ali Soleimanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Shalizar%20Jalai"> Ali Shalizar Jalai</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Sareafzadeh%20Rezaei"> Farshid Sareafzadeh Rezaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Testicular torsion and detorsion are significant clinical issues for infertile men. Torsion of the spermatic cord is an emergency condition resulting from the rotation of the testis and epididymis around the axis of the spermatic cord. A rat testis model was used to assess the effects of 尾-cryptoxanthin on ischemia-reperfusion injury. Twenty healthy male Wistar rats were included and randomized into four investigational groups (n = 5): Group SHAM: In this group, midline incision of the scrotum was performed, and the testicles were taken out for 2 hours with a 720-degree rotation. Group ISCHEMIA: In this group, a midline incision of the scrotum was performed, and the testicles were taken out and underwent ischemia for 2 hours with a 720-degree rotation. Group IS/REP/Oil: In this group, a midline scrotum cut was performed the testicles were taken out, and ischemia was created for 2 hours with a 720-degree rotation and at the end of ischemia 100 碌L of corn oil (尾-cryptoxanthin solvent) was injected intraperitoneally. Group IS/REP/CRPTXNTN 2.5: The same as group IS/REP/Oil as well as intraperitoneal administration of 100 碌L of 尾-cryptoxanthin (2.5 碌g/kg) at the end of ischemia. In all groups, the testes were returned back to the scrotum and, after 60 days, were dissected out and removed for histopathological analyses. 尾-cryptoxanthin at the dose of 2.5 碌g/kg significantly improved histologic indices compared to other treatment groups (p<0.05). 尾-cryptoxanthin could be helpful in minimizing ischemia-reperfusion injury in testicular tissue exposed to ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-cryptoxanthin" title="beta-cryptoxanthin">beta-cryptoxanthin</a>, <a href="https://publications.waset.org/abstracts/search?q=testis" title=" testis"> testis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ischemia-reperfusion" title=" Ischemia-reperfusion"> Ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Intraperitoneal" title=" Intraperitoneal"> Intraperitoneal</a> </p> <a href="https://publications.waset.org/abstracts/189306/the-effect-of-v-cryptoxanthin-on-testicular-ischemia-reperfusion-injury-in-a-rat-model-evidence-from-testicular-histology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189306.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">18</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> The Transcriptional Regulation of Human LRWD1 through DNA Methylation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yen-Ni%20Teng">Yen-Ni Teng</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsing-Yi%20%20Chen"> Hsing-Yi Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsien-An%20Pan"> Hsien-An Pan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yung-Ming%20%20Lin"> Yung-Ming Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hany%20A.%20Omar"> Hany A.

On the other hand, LRWD1 is significantly down-regulated in the testicular tissues of patients with severe spermatogenic defects. In our study, the downregulation of LRWD1 expression by shRNA caused a significant reduction of cell growth and mitosis and a noteworthy increase in the cell microtubule atrophy rate. Here, we used EMBOSS CpG plot analysis to explore the promoter region of LRWD1 gene. We found that CpG islands are located between positions -253 to +5 nucleotides upstream from the LRWD1 transcription start site. Luciferase reporter assay revealed that the hypermethylation of the LRWD1 promoter reduced the transcription activity in cells. In addition, quantitative methylation-specific PCR and immunostaining showed that the methylation inhibitor, 5-Aza-2'-deoxycytidine, increased LRWD1 promoter activity, LRWD1 mRNA, protein expression and cell viability. Whereas, the methylation activator, S-adenosylmethionine, caused opposite effects. The overexpression of p53 and Nrf2 in NT2/D1 cells increased LRWD1 promoter activity while 5-fluorodeoxyuridine decreased it. In conclusion, this study highlights evidence that the methylation status of LRWD1 promoter is associated with LRWD1 expression. Since the expression level of LRWD1 plays an important role in spermatogenesis, the methylation status of LRWD1 may serve as a novel molecular diagnostic or therapeutic approach in male's infertility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LRWD1" title="LRWD1">LRWD1</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20methylation" title=" DNA methylation"> DNA methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=p53" title=" p53"> p53</a>, <a href="https://publications.waset.org/abstracts/search?q=Nrf2" title=" Nrf2 "> Nrf2 </a> </p> <a href="https://publications.waset.org/abstracts/117435/the-transcriptional-regulation-of-human-lrwd1-through-dna-methylation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117435.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Effects of Injection of eCG and Oxytocin on Semen Characteristics of Zel Rams in Nonbreeding Season</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khosro%20Ghazvinian">Khosro Ghazvinian</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Narenji%20Sani"> Reza Narenji Sani</a>, <a href="https://publications.waset.org/abstracts/search?q=Touba%20Khodaiean"> Touba Khodaiean</a>, <a href="https://publications.waset.org/abstracts/search?q=Melika%20Moezifar"> Melika Moezifar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many previous studies have reported that eCG was effective for completing spermatogenesis.

Peripheral circulation of OT also, was increased during sex incitement and ejaculation The objective of this study was to investigate the effect of IM injection of eCG and OT on semen characteristics in Zel rams in out of breeding season. Eighteen 3-year-old Zel adult rams were randomly divided into five equal groups (control and four treatment groups). 0.9% NaCl (1 ml) was injected IM into each ram in the control group, whereas eCG was administered IM at a single dose of 400 IU and 600 IU to each ram in the two eCG treatment groups and OT was administered IM at a single dose of 5 IU and 10 IU to each ram in the other two OT treatment groups. Semen samples were taken by an electroejaculator from all rams 10 min after the IM injection of 0.9% NaCl, eCG, or OT. eCG did not alter semen volume, and OT did not alter sperm motility or abnormal sperm, in comparison to the control values. Mass activity, sperm motility and total sperm number increased significantly in eCG group compared to the control group; and semen volume, mass activity, total sperm number of the OT treatment groups increased significantly compared to the control group. Exogenous 600 IU eCG and 10 IU OT increase mass activity, total sperm number, lived sperm and sperm concentration in Zel rams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eCG" title="eCG">eCG</a>, <a href="https://publications.waset.org/abstracts/search?q=oxytocine" title=" oxytocine"> oxytocine</a>, <a href="https://publications.waset.org/abstracts/search?q=semen%20characteristics" title=" semen characteristics"> semen characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Zel%20Ram" title=" Zel Ram"> Zel Ram</a>, <a href="https://publications.waset.org/abstracts/search?q=nonbreeding%20season" title=" nonbreeding season"> nonbreeding season</a> </p> <a href="https://publications.waset.org/abstracts/47108/effects-of-injection-of-ecg-and-oxytocin-on-semen-characteristics-of-zel-rams-in-nonbreeding-season" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Electrophoretic Changes in Testis and Liver of Mice after Exposure to Diclofenac Sodium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Mohan">Deepak Mohan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sushma%20Sharma"> Sushma Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Asif"> Mohammad Asif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diclofenac sodium being one of the most common non-steroidal anti-inflammatory drugs is normally used as painkiller and to reduce inflammation. The drug is known to alter the enzymatic activities of acid and alkaline phosphatase, glutamate oxaloacetate transaminase and glutamate pyruvate transaminases. The drug also results in change in the concentration of proteins and lipids in the body. The present study is an attempt to study different biochemical changes electrophoretically due to administration of different doses of diclofenac (4mg/kg/body weight and 14mg/kg/body weight) on liver and testes of mice from 7-28 days of investigation. Homogenization of the tissue was done, supernatant separated was loaded in the gel and native polyacrylamide gel electrophoresis was conducted. Diclofenac administration resulted in alterations of all these biochemical parameters which were observed in native polyacrylamide gel electrophoretic studies. The severe degenerative changes as observed during later stages of the experiment showed correlation with increase or decrease in the activities of all the enzymes studied in the present investigation. Image analysis of gel in liver showed a decline of 7.4 and 5.3 % in low and high dose group after 7 days whereas a decline of 9.6 and 7.5% was registered after 28 days of investigation. Similar analysis for testis also showed an appreciable decline in the activity of alkaline phosphatase after 28 days.

To analyze the process of sex reversal, we have followed for several months the changes induced by Fadrozole, a nonsteroidal aromatase inhibitor on the morphology of female sex-reversed and female sex-reversed supplemented with L-tyrosine which was previously shown to stimulate the release of Gn Rh. Fadrozole (1mg/egg) was injected into eggs on day four of incubation, phenotypic males and phenotypic males treated with L-tyrosine and males hatched from eggs injected Fadrozole were sacrificed by slaughtering at 16 weeks old and the remaining chicks were sacrificed at 28 weeks old. Both sexes from control chickens were sacrificed at the same age (16 &28 weeks). Hatchability, behavior, body weight, shank length, comb weight, testes weight, blood cells count and wattle weight of sex reversal were tested at 16 and 28 weeks. The results showed that body weight, comb weight, wattles weight and shank length of sex-reversed females were significantly different from control female. Behavior of phenotypic males and phenotypic males fed on L- tyrosine showed aggressive sexual behavior like that of control males and absence of laying behavior. In conclusion our results confirm that Fedrazole injection in eggs before sex differentiation produce a male behavior and morphological index of male in female chicken. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sex%20reversal" title="sex reversal">sex reversal</a>, <a href="https://publications.waset.org/abstracts/search?q=fadrozole" title=" fadrozole"> fadrozole</a>, <a href="https://publications.waset.org/abstracts/search?q=phenotypic%20male" title=" phenotypic male"> phenotypic male</a>, <a href="https://publications.waset.org/abstracts/search?q=L-%20tyrosine" title=" L- tyrosine "> L- tyrosine </a> </p> <a href="https://publications.waset.org/abstracts/20237/effects-of-aromatase-inhibitor-fadrozole-induced-sex-reversal-in-chicken-gimmizah-strain-on-morphology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">610</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Origanum vulgare as a Possible Modulator of Testicular Endocrine Function in Mice </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tvrd%C3%A1">Eva Tvrd谩</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbora%20Babe%C4%8Dkov%C3%A1"> Barbora Babe膷kov谩</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20%C4%8Eura%C4%8Dka"> Michal 膸ura膷ka</a>, <a href="https://publications.waset.org/abstracts/search?q=R%C3%B3bert%20Kirchner"> R贸bert Kirchner</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%BAlius%20%C3%81rvay"> J煤lius 脕rvay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was designed to assess the <em>in vitro</em> effects of <em>Origanum vulgare</em> L. (oregano) extract on the testicular steroidogenesis. We focused on identifying major biomolecules present in the oregano extract, as well as to investigate its <em>in vitro</em> impact on the secretion of cholesterol, testosterone, dehydroepiandrosterone and androstenedione by murine testicular fragments. The extract was subjected to high performance liquid chromatography (HPLC) which identified cyranosid, daidzein, thymol, rosmarinic and trans-caffeic acid among the predominant biochemical components of oregano. For the <em>in vitro</em> experiments, testicular fragments from 20 sexually mature Institute of Cancer Research (ICR) mice were incubated in the absence (control group) or presence of the oregano extract at selected concentrations (10, 100 and 1000 μg/mL) for 24 h. Cholesterol levels were quantified using photometry and the hormones were assessed by ELISA (Enzyme-Linked Immunosorbent Assay). Our data revealed that the release of cholesterol and androstenedione (but not dehydroepiandrosterone and testosterone) by the testicular fragments was significantly impacted by the oregano extract in a dose-dependent fashion. Supplementation of the extract resulted in a significant decline of cholesterol (P < 0.05 in case of 100 μg/mL; P < 0.01 with respect 100 μg/mL extract), as well as androstenedione (P < 0.01 with respect to 100 and 1000 μg/mL extract). Our results suggest that the biomolecules present in <em>Origanum vulgare</em> L. could exhibit a dose-dependent impact on the secretion of male steroids, playing a role in the regulation of testicular steroidogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mice" title="mice">mice</a>, <a href="https://publications.waset.org/abstracts/search?q=Origanum%20vulgare%20L." title=" Origanum vulgare L."> Origanum vulgare L.</a>, <a href="https://publications.waset.org/abstracts/search?q=steroidogenesis" title=" steroidogenesis"> steroidogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=testes" title=" testes "> testes </a> </p> <a href="https://publications.waset.org/abstracts/108962/origanum-vulgare-as-a-possible-modulator-of-testicular-endocrine-function-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108962.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Effect of Visnagin on Altered Steroidogenesis and Spermatogenesis, and Testicular Injury Induced by the Heavy Metal Lead</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleh%20N.%20Maodaa">Saleh N. Maodaa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Lead (Pb) is an environmental pollutant causing serious health problems, including impairment of reproduction. Visnagin (VIS) is a furanochromone with promising antioxidant and anti-inflammatory effects; however, its protective efficacy against Pb toxicity has not been investigated. Objective: This study evaluated the protective effect of VIS on Pb reproductive toxicity, impaired steroidogenesis and spermatogenesis, oxidative stress and inflammation. Methods: Rats received VIS (30 or 60 mg/kg) and 50 mg/kg lead acetate for 3 weeks, and blood and testes samples were collected. Results: Pb intoxication impaired the pituitary-testicular axis (PTA), manifested by the decreased serum levels of gonadotropins and testosterone. Pb decreased sperm count, motility and viability, increased sperm abnormalities, and downregulated the steroidogenesis markers StAR, CYP17A1, 3尾-HSD and 17尾-HSD in the testis of rats. VIS significantly increased serum gonadotropins and testosterone, alleviated sperm parameters and upregulated steroidogenesis. In addition, VIS decreased pro-inflammatory cytokines, testicular lipid peroxidation and DNA fragmentation, downregulated Bax, and enhanced antioxidants and Bcl-2 Conclusion: These results demonstrate the protective effect of VIS against Pb reproductive toxicity in rats. VIS improved serum gonadotropins and testosterone, enhanced steroidogenesis and spermatogenesis, and attenuated oxidative injury, inflammation and apoptosis. Therefore, VIS is a promising candidate for the protection against Pb-induced reproduction impairment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pituitary-gonadal%20axis" title="pituitary-gonadal axis">pituitary-gonadal axis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokines" title=" cytokines"> cytokines</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage" title=" DNA damage"> DNA damage</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a> </p> <a href="https://publications.waset.org/abstracts/164996/effect-of-visnagin-on-altered-steroidogenesis-and-spermatogenesis-and-testicular-injury-induced-by-the-heavy-metal-lead" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Effects of Aromatase Inhibitor on Morphology and Body Shape in Sex-Reversal Chicken: Gimmizah Strain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Ashur%20Masoud%20Shreha">Hatem Ashur Masoud Shreha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aromatase inhibitors administered before sexual differentiation of the gonads in chicken embryo can induce sex reversal in female layer chickens (phenotypic male). To analyze the process of sex reversal, we have followed for several months the changes induced by Fadrozole, a nonsteroidal aromatase inhibitor on morphology of female sex-reversed and female sex-reversed supplemented with L-tyrosine which was previously shown to stimulate release of Gn Rh. Fadrozole (1mg/egg) was injected into eggs on day four of incubation before sex differentiation. phenotypic males and phenotypic males treated with L-tyrosine and males hatched from eggs injected Fadrozole were sacrificed by slaughtering at 16 weeks old and the remaining chicks were sacrificed at 28 weeks old. Both sexes from control chickens were sacrificed at the same age (16 &28 weeks). Hatchability, behavior, body weight, shank length, comb weight, testes weight, blood cells count and wattle weight of sex reversal were tested at 16 and 28 weeks. The results showed that body weight, comb weight, wattles weight and shank length of sex-reversed females were significantly different from control female. Behavior of phenotypic males and phenotypic males fed on L-tyrosine showed aggressive sexual behavior like that of control males and absence of laying behavior. In conclusion our results confirm that Fadrazole injection in eggs before sex differentiation produce a male behavior and morphological index of male in female chicken. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sex-reversal" title="sex-reversal">sex-reversal</a>, <a href="https://publications.waset.org/abstracts/search?q=fadrozole" title=" fadrozole"> fadrozole</a>, <a href="https://publications.waset.org/abstracts/search?q=phenotypic%20male" title=" phenotypic male"> phenotypic male</a>, <a href="https://publications.waset.org/abstracts/search?q=L-tyrosine" title=" L-tyrosine "> L-tyrosine </a> </p> <a href="https://publications.waset.org/abstracts/24510/effects-of-aromatase-inhibitor-on-morphology-and-body-shape-in-sex-reversal-chicken-gimmizah-strain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24510.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">452</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> The Effect of Lepidium Meyenii on Viability, Motility, and Sperm Morphology in Treatment of Infertility Among Adult Male Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arefeh%20Sabzipour">Arefeh Sabzipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, the effect of Lepidium meyenii on viability, motility, and sperm morphology in the treatment of infertility of adult male Wistar rats was evaluated. 21 male Wistar rats were adopted, fed and brought up in the same conditions to reach the weight of 230卤5 g. after that, they were randomly divided into three groups, including two experimental groups and one control group, each group consisted of 7 rates. Lepidium meyenii was extracted and pulverized. Mice in the control group were treated with distilled water, and experimental groups were gavage with alcoholic juice extracted from Lepidium meyenii once a day for 10 consecutive days. After rates were killed, the testes were isolated. Different parameters includes semen volume in mice, sperm count, sperm motility, morphology, and viability, were evaluated. The results shows that sperm motility and sperm survival indices were significantly different between groups, and sperm count and sperm morphology indices were not significantly different. Sperm motility index in intervention group 1 was equal to 77.00卤2.499 and was significantly higher than the one in intervention group two (70.14卤3.579, P=0.018) and control group (69.43 卤7.323, P=0.018). Sperm survival index was 91.14 卤 2.410 in intervention group 1, 79.43卤 5.062 in intervention group 2, and 76.71.6.651 in the control group (P<0.001). Based on the results of the present study, Lepidium meyenii had great effect on improving sperm indices of mice, especially sperm motility index and sperm survival index. Sperm count index and sperm morphology index, although increased, were not statistically significant. <p class="card-text"><strong>Keywords:</strong> <a
