Effect of progesterone on the sebaceous glands.
The effect of progesterone on the rate of sebum secretion was examined in intact and gonadectomized male and female rats. In intact adult male rats, progesterone administered for 3 weeks decreased sebum secretion, whereas in intact adult female rats, progesterone slightly increased sebum production. In castrated adults progesterone increased sebum secretion in both sexes, a greater response occurring after castration at 21 days of age than after castration at 10 weeks. Thus, the response to progesterone in the adult rat differs in intact males and females and is affected by changes in the endocrine environment induced by gonadectomy, especially near the time of puberty.
