ABSTRACT
Background: To compare two protocols comprising of FSH/CC/HMG and CC/HMG for ovulation induction and IUI in women with infertility.Methods: 60 women with unexplained infertility were randomized using sequentially numbered opaque envelope method. Group A received inj FSH 150 units on day 2 of menstrual cycle and clomiphene citrate 100 mg from day 3-7, followed by injection HMG 150 units on day 9 of menstrual cycle. Group B received clomiphene citrate 100 mg from day 3-7, and HMG 150 units on day 7 and 9 of the menstrual cycle. Ovulation triggered with hCG 5000 units when dominant follicle was 18mm. Single IUI was done 36-42 hours afterwards.Results: Pregnancy occurred in 3 out of 30 women in 116 cycles Group A (with FSH) with a pregnancy rate of 10 percent, and 2.8% per cycle. In group B (without FSH) pregnancy occurred in 3 out of 30 women in 117 cycles with pregnancy rate of 10 percent, and 2.6% per cycle. The number of follicles per cycle was 1.36 and follicle size was 18.57 mm in group A. While in Group B numbers of follicles per cycle were 1.22, with average size of 18.9mm. Mean endometrial thickness was 7.7mm in Group A and 6.37 in Group B (p=.01, significant). Mild OHSS was observed in one woman in Group B. No other side effects were observed in both the groups.Conclusions: The controlled ovarian stimulation regimes used in this study are equally effective, easy to administer, require less intensive monitoring and fewer medications, with little risk of OHSS and multiple gestation.
