Abstract
BACKGROUND
The role of midluteal phase gonadotropin-releasing hormone (GnRH) agonist had been an issue of debate. The aim of this retrospective study was to evaluate the effect of a mid-luteal phase GnRH agonist as an additional luteal phase support (LPS) in patients receiving intracytoplasmic sperm injection (ICSI). Additionally, we elucidate which subgroup would gain the most benefit from GnRH agonist as LPS.
METHODS
The medical records were retrieved from January 2009 to January 2012 and a total of 348 patients receiving ICSI were included in this retrospective study. Among them, 240 patients met the inclusion criteria of patients aged ≤ 38 years, previous assisted reproductive technology (ART) cycles ≤ 2. There were 147 patients in the decapeptyl group who received GnRH agonist decapeptyl 6 days after ICSI as additional LPS and 93 patients in the control group. Subgroupings were done according to advanced age, the number of previous ART cycles, high basal follicle-stimulating hormone (FSH) level, and patients who had fewer mature oocytes retrieved. Live birth rates, clinical pregnancy rate (CPR), and implantation rate were the primary outcomes.
RESULTS
LPS with decapeptyl led to a higher implantation rate (24.5% vs. 17.0%, p = 0.023), a higher CPR (49.0%, n = 72 vs. 33.3%, n = 31, p = 0.023) and a higher live birth rate (41.5%, n = 61 vs. 28.0%, n = 26, p = 0.039). In the subgroup analysis, decapeptyl improved the CPR of those patients with basal FSH >8 mIU/mL (50.0%, n = 15 vs. 8.3%, n = 1, p = 0.031) and also improved CPR (42.3%, n = 11 vs. 0%, n = 0, p = 0.017) and live birth rate (30.8%, n = 8 vs. 0%, n = 0, p = 0.035) of patients whose number of mature oocytes was three or fewer.
CONCLUSION
This study demonstrated that administration of decapeptyl as additional luteal support can enhance ICSI clinical outcomes. Those patients with higher basal FSH level or fewer number of mature oocytes may obtain particularly significant benefit.
