title: [Characteristics of the hypothalamo-hypophyseal regulation and morphological and functional state of the reproductive organs in female rats, androgenized in the neonatal period, depending on the time of the action of testosterone].
abstract: Testosterone propionate was injected to rats in a dose of 150 microng on the 2nd, 3rd and 4th day or in a dose of 500 microng on the 5th day after birth. Histological picture of the ovaries, vagina and uterus, the content of progesterone and its C20-restored metabolite in the ovaries, the LH-releasing activity of the hypothalamus, and the LH and FSH in the adenohypophysis were studied in these rats at the age of 3-5 months. The effects of the neonatal andronization of rats proved to depend on the time of testosterone action at all the levels of the hypothalamus-hypophysis-ovaries-accessory organs. Early administration of androgen caused more severe injuries of the reproductive system.
