IlUlI steriodal synthetic compound with both estrogenic and anti-estrogenic activity, is the most common agent in clinical me for ovul ation iad tl etion with minimal side effects of a clinically acceptable frequency Its application for induction of ovulation has resulted in high success rates of 55 % to 99 %, however, conception rates of patients are only between 25 % and 43 %. This discrepancy between ovulation and conception rates lias been attributed to several clomiphene citrate induced factors, including inadquate maturation of the : endometrium. The effects may involve steroid receptor mechani ”til, Several studies has heen done to study the effect of clomiphene citrate treatment on endometrial estrogen receptor levels with controversal results, The present study aimed to study the effect of clomiphene citrate 011 late secretory endometrial estrogen receptors level and its effect on endometrial dating to find out a possible came fur the discrepancy between the incidence of induction of ovulation using it and the occurrance of pregnancy. Thirty females were the subjects ofthis study. They were classified into two groups. The first group was included (10) normally ovulating volunteers who were using barrier contraceptive methods or having tobal ligation, The second group was _included (20) infertile non ovulating females, who were given 1S0 mg CC. at the fifth day of the cycle for f days. Monitoring uf ovulation was done by basal body temperature records and by llhn:18L)!UC Iolliculomerry and was confirmed by the endometrial biopsy, Premenstrual endometrial biopsy (day 25 ·28) war, taken from the uterine fundus for each participant, R - HCG estimation was done [Of women Oil Cc. and women who use barrier contraceptive methods to roll out fertilization before taking the biopsy. |
