Abstract
Exponential rise rate(ERR) of serum estradiol concentrations during active follicular phase was calculated for 49 ovulation induction cycles by human menopausal gonadotropin to know the ovulation induction outcome according to ERR classified into 3 groups with low, moderate and high ERR values(Group I${\leqq}$0.3, 0.3${\leqq}$0.6,Group III>0.6). The results were summarised as follows : 1. No significant difference in the dosage of human menopausal gonadotropin was identified in each group. 2. The mean serum estradiol concentration at the day of human chorionic gonadotropin injection in Group II and Group ill was significantly higher than that in Group I . 3. The mean diameter of leading follicles at the day of human chorionic gonadotropin injection showed no significant difference in each group. 4. No significant difference in the ovulation rate was observed in relation to ERR. How ever, 20% and 20.8% of pregnancy rate in Group I and Group II were achieved while no pregnancy was occurred in Group III. 5. The ovarian hyperstimulation frequency was significantly higher in Group ill that in Group I and Group II. In conclusion, the study suggests that exponential rise rate of serum estradiol is a useful tool in HMG ovulation induction by preventing ovarian hyperstimulation without reducing pregnancy success rate.
