Abstract
Purpose
An alternative option to human chorionic gonadotropin (hCG) is GnRH agonist (GnRH-a) for ovulation trigger in intrauterine insemination (IUI) cycles. This study aims to compare the efficacy of GnRH-a with hCG in women with history of follicular–endometrial asynchrony after clomiphene in IUI cycles.
Methods
This prospective observational study recruited 631 women with unexplained infertility and follicular–endometrial asynchrony (follicle ≥ 18 mm, endometrial thickness (ET) < 7 mm) in previous two failed clomiphene/IUI cycles. Overall 27 patients with synchronized follicular–endometrial relationship and 49 women with persistent ET < 7 mm and/or follicle > 26 mm were excluded. Remaining women (n = 555) were divided into two groups: Group A (n = 285) received GnRH-a and Group B (n = 270) received hCG ovulation trigger. Finally, 513 patients, who underwent IUI, were analysed.
Results
Cancellation due to luteinized unruptured follicle was more in hCG group (P = 0.01). Higher clinical pregnancies (10.33 vs. 4.96%, P = 0.03) and live birth rates (8.86 vs. 4.13%, P = 0.03) were noted with GnRH-a trigger. Miscarriage rate was comparable in both the groups (10.71 and 16.67% in Group A and Group B, respectively).
Conclusion
In unexplained infertility, GnRH agonist is an useful alternative for triggering ovulation in women with follicular–endometrial asynchrony following clomiphene induction.
