Abstract
Administration of FSH antiserum to adult rats for 14 or 30 days had no or little effect on body, testis or accessory sex gland weights, androgen-binding protein, testosterone levels, germ cell numbers or fertility, thus indicating a relative insensitivity of the testis to withdrawal of FSH. Unlike immature rats, therefore, which do require FSH to initiate spermatogenesis, adult rats do not need this hormone to maintain spermatogenesis.
