Objective:
To evaluate the efficacy of the GnRH agonist (GnRHa) administered in conjunction with human menopausal gonadotropin/human chorionic gonadotropin hMG/hCG and direct intraperitoneal insemination (DIPI) in women with long-standing unexplained infertility.
Study Design:
A prospective, randomized, non-blind analysis. During the period May 1995-December 1996, couples with unexplained infertility who failed to conceive following superovulation combined with IUI for at least seven cycles were prospectively enrolled and followed. Pregnancy rates per cycle and per patient of DIPI were compared between groups of hMG/hCG with (GnRHa[+] controlled ovarian hyperstimulation [COH] group) or without (GnRHa[-] COH group) GnRHa.
Results:
Thirty-four women (59 cycles) underwent COH with hMG and GnRHa, and 31 women (49 cycles) received hyperstimulation with hMG alone. The pregnancy rates for the women administered GnRHa significantly exceeded those of the patients who did not receive GnRHa both per treatment cycle (35.6% versus 14.3%) and per couple (55.9% versus 22.5%).
Conclusion:
The use of GnRHa with hMG/hCG and DIPI treatment significantly increased the pregnancy rate in women with long-standing infertility.
