Abstract |
Objectives |
To evaluate the effectiveness of dual trigger using gonadotropin-releasing hormone (GnRH) agonist and recombinant human chorionic gonadotropin (rHCG) versus rHCG alone for normal responders in GnRH antagonist intracytoplasmic sperm injection (ICSI) cycles.
Patients and methods |
The current study was a registered open-labeled randomized controlled trial (clinical trial.gov: NCT02916173) conducted in the ART Unit of a tertiary University hospital between October 2016 and October 2018. The study participants were randomized to either group I (HCG group) or group II (dual trigger group). The primary outcome was the number of mature (MII) oocytes in both groups.
Results |
Both groups were similar regarding the baseline demographic and clinical characteristics. Women in the dual trigger group had a statistically significant higher number of retrieved oocytes (p = 0.001), MII oocytes (p = 0.01) and the number of grade one embryos (p = 0.04). Both groups were similar regarding the fertilization, implantation, clinical pregnancy and live birth rates in a fresh cycle. Dual trigger group was significantly higher in the clinical pregnancy rate and live birth rate after frozen embryo transfer (p = 0.04, 0.03, respectively).
Conclusion |
Dual trigger by GnRH agonist and rHCG improve the oocyte maturity and embryo grading for normal responders in GnRH antagonist ICSI cycles.
