摘要: The present study examined the relationship between functional status of Sertoli cells and maintenance restoration spermatogenesis in immature hypophysectomized (HPX) rats given various doses exogenous testosterone with or without daily injections FSH for 90 days. Subcutaneous implantation a 2- to 10-cm capsule (TC) increased serum levels HPX 2–10 times above normal control levels, but did not significantly increase testicular level. Daily accumulation testes TC-implanted rats. Maintenance early spermiogenesis was observed all animals. Although elongated spermatids were present, step 18-19 at luminal edge stages VII-VIII epithelium only bearing TC implants. injection resulted completion TCimplanted animals, number 18–19 wa...
