Abstract

OBJECTIVE

To compare the clinical outcomes of gonadotropin-releasing hormone (GnRH) antagonist (GnRH-ant) fixed protocol with GnRH agonist (GnRH-a) long protocol in infertile patients with normal ovarian reserve function in their first in vitro fertilization-embryo transfer (IVF-ET) cycle, and to explore the feasibility and advantage of GnRH antagonist protocol performed in normal responders.

METHODS

From January 2011 to June 2011, 771 infertile women with normal ovarian reserve function underwent their first IVF or intracytoplasmic sperm injection (ICSI) cycles in Peking University Third Hospital, which were divided into 245 cycles in GnRH-ant fixed protocol group (GnRH-ant group) and 526 cycles in GnRH-a long protocol group (GnRH-a group). The data of general demographic, treatment and clinical outcome were compared between two groups.

RESULTS

Age, infertile duration, body mass index (BMI), baseline serum follicle-stimulating hormone (FSH) and estradiol levels between two groups did not reached statistical difference (P > 0.05). The level of estradiol was (12 289 ± 6856) pmol/L in GnRH-ant group and (14 934 ± 8007) pmol/L in GnRH-a group at day of hCG injection. The mean length of stimulation was (10.3 ± 1.2) days in GnRH-ant group and (12.8 ± 1.6) days in GnRH-a group. The dose of gonadotropin was (2013 ± 607) U in GnRH-ant group and (2646 ± 913) U in GnRH-a group. The number of ovum was 15 ± 7 in GnRH-ant group and 17 ± 8 in GnRh-a group. Those clinical parameter all reached statistical difference (P < 0.05). The number of embryo was 7 ± 4 in GnRH-ant group and 8 ± 5 in GnRH-a group, the rate of clinical pregnancy was 40.9% (94/230) in GnRH-ant group and 45.6% (216/474) in GnRH-a group, the rate of implantation was 26.1% (128/490) in GnRH-ant group and 30.9% (307/994) in GnRH-a group, the rate of continuing pregnancy was 38.7% (89/230) in GnRH-ant group and 42.6% (202/474)in GnRH-a group, those parameter did not reach statistical difference (P > 0.05). The rate of moderate or severe ovarian hyperstimulation syndrome was 2.4% (6/245) in GnRH-ant group and 4.2% (22/526) in GnRH-a group, which did not show significant difference (P > 0.05).

CONCLUSION

In the first IVF or ICSI cycle of the patients with normal ovarian reserve function, the fixed GnRH-ant protocol could get the same satisfied clinical outcome, and it is more economic, convenient and safer compared with low dose depot GnRH-a long protocol.
