Spontaneous ovulation, hormonal profiles, and the impact of progesterone timing variation on outcomes in natural proliferative phase frozen embryo transfer cycles with single euploid blastocyst transfer
Abstract Background Natural cycle frozen embryo transfer (NC-FET) lowers obstetric risks by preserving ovulation and corpus luteum but limits scheduling flexibility. Natural proliferative phase FET (NPP-FET) offers a scheduling-friendly alternative, assuming ovulation is maintained after flexible pr...
