Objective To investigate the effect of gonadotropin-releasing hormone agonist (GnRH-a)
combined with low-dose human chorionic gonadotrophin (hCG) on the clinical outcome of in-vitro fertilization-embryo
transfer (IVF-ET) in patients with high ovarian response. Methods A retrospective analysis was performed on the clinical
data of 546 patients who underwent controlled superovulation stimulation via (IVF/ICSI) in our hospital from December
2016 to December 2017. Patients adopting GnRH-a + 5 000 IU hCG dual-trigger (hCG high dose group, n=159) or
GnRH-a + 2 000 IU hCG dual-trigger (hCG low dose group, n=212) were enrolled. Those using the standard hCG 10 000 IU
trigger were involved as a control group . The treatment outcome of each group was compared. Results There was no
significant differences in basic dosage or medication time of gonadotropin trigger among the three groups (P >0.05). The
serum levels of estradiol (E2) on ovulation induction day in the high-dose hCG group [(17 513.52±4 846.85) pmol/L]
and the low-dose hCG group [(20 384.11±7 754.78) pmol/L] were significantly higher than those in the control
group [(16 678.67±3 826.79) pmol/L] (P=0.000). The number of retrieved oocytes, number of 2PN embryos, number
of embryos, number of high-quality embryos, and rate of high-quality embryos in both test groups were all significantly

higher than incontrol group (P <0.05). The rate of high-quality embryos in hCG high dose group was significantly larger
than in hCG low dose group. There were no statistically significant differences in clinical pregnancy rates (53.7%, 50.0%,
51.9%), ectopic pregnancy rates (10.3%, 14.3%, 0%) and abortion rates (10.3%, 0%, 7.1%) among the three groups,
Tnumber of ovarian hyperstimulation syndrome (OHSS)and the incidence of OHSS rate (2.9%, 1.3%, 0.5%) were not
significantly different (P >0.05). Conclusion For patients with high response to GnRH antagonist regimen, the use of
low-dosage dual-trigger can increase the rate of high-quality embryos and the number of transferrable embryos without
increasing the incidence of OHSSs.
