Abstract |
Background |
Poor ovarian response (POR) to ovarian hyperstimulation is one of the biggest challenges in assisted reproduction technology. The objective of this study was to compare the efficacy of progestin-primed ovarian stimulation (PPOS) with a GnRH antagonist (GnRH-ant) in poor ovarian response (POR) patients.
Materials and methods |
This retrospective analysis included a total of 186 cycles of POR patients between 2014 and 2016. The patients were divided into two groups according to the method of stimulation protocol, as follows: 63 cycles were PPOS, and 123 cycles were GnRH-ant. Reproduction-related clinical outcomes in the two groups were compared.
Results |
There were no significant differences in patients’ age, dose and duration of gonadotropin (Gn) treatment, serum luteinizing hormone (LH) and E2 levels on the day of hCG injection, or the number of oocytes retrieved between the two groups. The MII oocyte rates, fertilization rates, good-quality embryo rates were significantly higher in the PPOS group than they were in the antagonist group (p<0.05). In the subsequent frozen-thawed embryo transfer (FET), clinical pregnancy and live birth rates were significantly higher in the PPOS group than they were in the antagonist group (p<0.05).
Conclusions |
Compared with the GnRH-ant protocol, the PPOS protocol may be a better regime for POR that can effectively improve clinical pregnancy and live birth rates.
