Effect of superovulation combination therapy containing Clostilbegyt (clomiphene citrate) on follicular development and the endometrium.

The effect of Clostilbegyt + Humegon + Pregnyl ovulation inductive combination therapy was examined in the woman members of 20 sterile couples appearing at the Outpatient Department of Cryospermatology, Department of Obstetrics and Gynaecology Postgraduate Medical School. In 18 of the 20 cases follicle maturation and ovulation could be induced. In the male members of the couples therapy-resistant sterility existed at the same. By using artificial insemination by donors with cryopreserved sperms, gravidity could be obtained in 14 cases. The importance of the optimal timing of AID has been emphasized. In the course of transvaginal ultrasonography folliculometry was completed with the control of the pre-ovulatory changes of the endometrium. The appearance of the pre-ovulatory ring preceded the occurrence of pregnancy in all cases, being a sign of predictive value considering conception.
