摘要: The normal physiology of the hypothalamic-pituitary-testicular axis in man is reviewed. According to current concepts, LH plays an important role initiation and maintenance spermatogenesis by stimulating Leydig cell production high concentrations T within testes. FSH thought be spermatid maturation (spermiogenesis) during stimulation Sertoli cells. Studies selective gonadotrophin replacement experimentally-induced hypogonadotrophic hypogonadal men demonstrate that qualitatively sperm can achieved either or alone, but both are necessary maintain quantitatively spermatogenesis. spontaneously-occurring suggest requirement for activity stimulate greatest at time puberty. postpubertal with acquired hypogonadism after its often alone.
