Abstract

Abstract:

Objective To analyze the clinical outcomes of progestin primed ovarian stimulation (PPOS) compared with the other three different controlled ovarian hyperstimulation (COH) protocols in fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET) cycles. Methods A total of 430 oocyte pickup cycles and 272 FET cycles were retrospectively analyzed. Number of oocytes retrieved, laboratory indexes and pregnancy outcome of FET were compared. Results The mean oocytes retrieved (11.1±7.3), fertilization rate (85.6%), cleavage rate (95.1%) and excellent embryo rate (20.2%) as well as transplantable embryo rate (4.5±3.1) of the PPOS group did not show significant differences compared with the other 3 subgroups (all P<0.05) in fresh cycle. As for pregnancy outcomes in FET cycles, no statistically significant differences were observed among the four groups in embryo implantation rate (26.2%), clinical pregnancy rate (63.0%) and abortion rate (11.8%) (all P<0.05)．However, embryo implantation rate, clinical pregnancy rate was higher in PPOS group compared with the other groups. Conclusion Conclusion Compared with the other three ovulation stimulation programme, PPOS might be used as a new alternative for controlled ovulation stimulation protocols.
