title: [Significance of 17-hydroxyprogesterone for the diagnosis of ovulation].
abstract: In 30 sterility patients with normal course of the cycle, 17 OHP already rises significantly one day before the LH-peak. It influences not only progesterone and E2 but also hypothalamic opiate activity and LHRH and LH secretion. 17 OHP is on the one hand discussed as a further trigger for the LH peak and is on the other hand regarded as an initiator for incipient luteinization.
