Биоактивные вещества эпифиза в регуляции сперматогенеза

Mitotic index of type B spermatogonia in intact animals is characterized by a circadian rhythm. Mitotic index increased and its circadian rhythm disappeared after pinealectomy. Treatment with Epitalamin for 14 days restored the circadian rhythm. The biorhythm of spermatogonia proliferation suggests the presence of circadian rhythm of spermatogenesis in general and its regulation by the pineal gland.
