title: Maintenance of spermatogenesis induced by HMG treatment by means of continuous HCG treatment in hypogonadotrophic men.
abstract: In a long-term hypophysectomized male HCG treatment was unable to initiate spermatogenesis. However, a spermatogenesis induced by HMG/HCG treatment could be maintained by HCG alone for 7 years with clinical fertility. In another hypogonadotrophic male HCG was also unable to initiate spermatogenesis. But a spermatogenesis once induced by HMG/HCG treatment could be maintained for more than one year with HCG alone. It is suggested that gonadotrophin treatment of the hypogonadotrophic male should consist of HMG + HCG until complete spermatogenesis is induced followed by maintenance treatment with HCG.
