[The neuroendocrine mechanisms of the development of the anovulatory hyperandrogenic syndrome in rats].
The anovulatory syndrome in adult female rats occurred after subcutaneous implantation of silastic capsules with testosterone. Acceleration of testosterone conversion into estradiol in the hypothalamus, suppression of pituitary LH responsiveness to LHRH, increase of blood plasma bioactive LH, estrous cycle disorder as well as morphological changes in ovaries demonstrate the alterations in neuroendocrine control of ovulation.
