Efforts to develop new method for men have been made during recent decads, but the most reliable method is still sterlization by vasectomy. The ue of GnRH antagonist for fertility regulation requites androgen supplementation to offset the decrease in serum testoster...

It is generally agreed that the testis is under endocrine control from the pituitary, and is influenced by physiological and paracrine factors within the organ. The aim of this study is to analyze the effect of unilateral and bilateral epididectomy on the testicular tissue growth of rats. Twentyone male old Sprague-Dawley rats (28 days old) were used in the study. Rats were assigned into 3 equa...
متن کاملThe effects of heat on the testes of mammals
Advances since my last review in 1998 on our understanding of the effects of heat on the testis are summarized. Techniques used to study these effects have included exposing the whole animal to a hot environment, insulation of the whole scrotum or just its neck, immersing the testes in a warm water bath, surgically returning one or both testes to the abdominal cavity (induced cryptorchidism) or...
متن کاملEffects of methotrexate exposure on medaka (Oryzias latipes) testes
For the purpose of clarifying the histopathological effects of methotrexate (MTX) on medaka testes, wild-type and homogenic p53-deficient male medaka at 4 to 6 months post-hatching were exposed to 0.25 mg/ml of MTX for 96 h with histopathological examination of testes at 24, 48, 72 and 96 h. At 72 and 96 h after the start of MTX exposure, numerous apoptotic cells were observed in the spermatogo...
متن کاملEffects of cadmium exposure on medaka (Oryzias latipes) testes
Adult male medaka (Oryzias latipes) were exposed to 10 ppm of cadmium for 96 h, and the testes were examined histopathologically. Numerous apoptotic cells were found in the spermatogonia and spermatocytes at 72 and 96 h after initiation of cadmium exposure, and the pyknotic index, TUNEL-positive rate, and cleaved caspase-3-positive rate in the spermatogonia and spermatocytes of the cadmium-trea...
