Serum concentrations of medroxyprogesterone acetate were undetectable on OPU+5 days and had no effect on the serum progesterone level in patients undergoing the progestin-primed ovarian stimulation protocol
Frontiers in endocrinology ·doi:10.3389/fendo.2025.1490839

OBJECTIVE: To evaluate the dynamics of serum medroxyprogesterone acetate (MPA) concentrations and their influence on serum progesterone (P) levels and pregnancy outcomes in the progestin-primed ovarian stimulation (PPOS) protocol. A total o…

The comparison between fixed versus degressive doses of medroxyprogesterone acetate combined with letrozole in patients of progestin-primed ovarian stimulation protocol: a propensity score-matched study
Frontiers in endocrinology ·doi:10.3389/fendo.2023.1295787

OBJECTIVE: To explore the cycle characteristics and pregnancy outcomes of progestin-primed ovarian stimulation (PPOS) using fixed versus degressive doses of medroxyprogesterone acetate (MPA) in conjunction with letrozole (LE) in infertile w…

The serum oestradiol/progesterone ratio on the day of OPU + 7, but not the day of OPU + 5, affects the rates of live birth in fresh blastocyst embryo transfer cycles
Journal of ovarian research ·doi:10.1186/s13048-023-01096-3

BACKGROUND: In an in vitro fertilization (IVF) cycle, the embryo ends its wandering time and begins the process of implantation into the uterine cavity on the seventh day after oocyte pick-up (OPU + 7), which is closer than OPU + 5 to the t…
