introduction: the impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male wistar rats (80-100 g body weight). material & method: it was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight along...

Background The present study describes the susceptibility of prepubertal testis of mice to prooxidant induced oxidative impairments both under in vitro and in vivo exposure conditions. MaterialsAndMethods Following in vitro exposure to iron (5,10 and 25 M), oxidative response measured in terms of lipid peroxidation and hydroperoxide levels in testis of pre pubertal mice (4 wk) was more robust c...

splenogonadal fusion is a rare congenital malformation whereby the splenic tissue is found attached or surrounded by the testis, and presents in both continuous and discontinuous forms. splenogonadal fusion may be misinterpreted as a primary malignant testicular or an adenomatoid tumor. knowledge about the existence of such an entity is essential in order to preserve the testis during surgical ...

congenital undescending testis is a common anomaly of testis, but we had a rare case of ectopic testis. a 15-month-old infant was operated emergently because of left incarcerate inguinal hernia. intraoperative exploration of hernial sac revealed two ectopic testes with one spermatic cord proximally but in the middle divided to two spermatic cords in a 8 shape. there was an important point about...

Unilateral orchidectomy (UO) is required when further breeding potential is important. It is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. In this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. Results of the study showed that each of the surgica...

  SUMMARY With the aim of surgical epidemiology nature of undescended testis, we examined 8034 school age boys in the city of Tehran. We invatted affected persons to Loghman-e-Hakim Medical Center for repeated examination and further diagnostic in­vestigations, results are: Among 8034 persons 82 had undescended testis, it means 1 .02 % , 56 % are in the right, and 33%  in the left, 11 % are...

Background: Male infertility is responsible for approximately 50% of infertility in the world. Reactive oxygen species (ROS) is one of the causative agents of infertility in males which effects on sperm quality and function. In this study, the effects of oxidative stress induced by tertiary-butyl hydroperoxide (TBHP) were investigated on sperm quality, testis tissue and miRNAs expression. Mater...

background breast cancer is the most common malignancy in women around the world so finding new biomarkers for early detection and also study on molecular aspects of breast cancer is valuable. cancer testis genes are a group of genes expressed solely in testis and in a range of human malignancies. objectives in this study we determined the expression of cancer testis genes tsga10, tex101 and od...
