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.
摘要
给成年大鼠注射促卵泡激素（FSH）抗血清14天或30天，对其体重、睾丸或附属性腺重量、雄激素结合蛋白、睾酮水平、生殖细胞数量或生育能力没有影响或影响很小，这表明睾丸对FSH撤除相对不敏感。因此，与确实需要FSH来启动精子发生的未成熟大鼠不同，成年大鼠不需要这种激素来维持精子发生。
