[Determination of the ovulation date in stimulated cycles with Clostilbegyt]

Modern sterility therapy presupposes a precise ovulation timing in stimulated cycles. The different contribution and importance clinical hormono-analytical and ultrasonographic methods to and for the determination of the ovulation date were tested in 137 cycles of 84 women with a Clostilbegyt therapy as well as in a control group of 27 spontaneous cycles. It was stated that the results ascertained by ultrasonography are of special importance. Nevertheless the determination of 17 beta-estradiol and the LH estimation must not be neglected as functional criteria. In order to supervise the corpus luteum phase determinations of progesterone, 17 beta-estradiol and prolactin during the second part of the cycle are to be included into a control program.
