Mechanisms for central nervous system control of pituitary gonadotropin secretion and the effects of gonadotropins on gonadal function. Major physiological and clinical questions being addressed include: (1) Can a safe, effective, reversible contraceptive for men be developed? (2) What are the effects of aging on the male reproductive endocrine system? (3) What are the effects of androgens in men and women? (4) What are the relative roles of LH and FSH in controlling testicular function?
