Mechanisms for control of intratesticular steroidogenesis and the effects of gonadotropins and exogenous hormones on gonadal function. Major physiological and clinical questions being addressed include: 1) Why do hormonal contraceptives work for some men, but not others? 2) What are the minimal intratesticular hormones required for spermatogenesis? 3) Can intratesticular steroid concentrations predict male infertility and be used to develop specific therapies?
