ABSTRACT
The adenohypophyses of androgenised female rats contain significantly less prolactin than control animals. Testosterone phenylpropionate administered in the early postnatal period does not markedly change the adenohypophysial prolactin content of male rats. Since examination of the mammary gland provide no evidence of increased prolactin secretion, the decrease in the adenohypophysial prolactin content of androgenised female rats must be explained by reduced hormone production. It is suggested that androgenisation in female rats influences prolactin production by an action on the hypothalamus.
