Examination of the follicular maturation influencing effect of Clostilbegyt by endocrinous and electronic monitoring.

: The follicle maturation influencing effect of Clostilbegyt (50 mg Clomiphene-citrat) has been examined in 30 women suffering from primary or secondary sterility. For monitoring follicular development a vaginal ultrasound scanner was used. The development of yellow body and its adequate function have been controlled with serum progesterone determination. In the first therapeutical cycle daily 1 tbl. Clostilbegyt was used from the 4th day of the menstruation in a five day period. In the next cycle daily 2 tbl. were administered similarly. If the therapy was unsuccessful, then 3 tbl. per day Clostilbegyt was used as treatment in the 3rd cycle. In the course of monitoring with vaginal ultrasound scanner successful ovulation induction has been proved in 80% of the Clostilbegyt treated cases (in 24 of 30 cases). During the examination period pregnancy occurred in 7 cases (29.2%). Vaginal ultrasound monitoring is recommended by the author for ovulation induction therapy.
