ObjectiveTo determine whether an additional follicle-stimulating hormone (FSH) bolus administered at the time of the human chorionic gonadotropin (hCG) trigger can improve the developmental competence of the oocyte.DesignRandomized, double-blind, placebo-controlled, clinical trial.SettingAcademic medical center.Patient(s)Women undergoing a long agonist suppression in vitro fertilization (IVF) protocol for treatment of infertility.Intervention(s)FSH bolus at time of hCG trigger versus placebo.Main Outcome Measure(s)Primary outcome; fertilization; secondary outcomes: oocyte recovery, implantation rate, and clinical and ongoing pregnancy/live birth rates.Result(s)A total of 188 women (mean age: 36.2 years; range: 25 to 40 years) were randomized. Fertilization (2PN/#oocyte) was statistically significantly improved in the treatment arm (63% vs. 55%) as was the likelihood of oocyte recovery (70% vs. 57%). There was no statistically significant difference in clinical pregnancy rate (56.8% vs. 46.2%) or ongoing/live birth rate (51.6% vs. 43.0%).Conclusion(s)Improvements in IVF success rates have largely been due to optimization of embryo culture and stimulation protocols; less attention has been directed toward methods to improve induction of final oocyte maturation. This was the first randomized, double-blind, placebo-controlled trial to modify the ovulation trigger to improve oocyte competence, as demonstrated by the statistically significant improvement in fertilization.
