PLASMA LEVELS OF TESTOSTERONE IN MALE RABBITS FOLLOWING COPULATION

Abstract

Summary. Normal, male rabbits were either allowed to copulate with receptive females, or were injected with human chorionic gonadotrophin (hcg), or with adrenocorticotrophic hormone (acth). Copulation and hcg injection produced significant increases in plasma testosterone while acth administration failed to do so. Rabbits treated with either chloropromazine or fluoxymestrone before copulation did not increase plasma levels of testosterone following coitus.
