Subtle progesterone rise on the day of hCG administration is associated with lower live birth rates in women undergoing assisted reproductive technology: a retrospective study with 2,555 fresh embryo transfers
In this retrospective, observational, cohort study with 2,555 women, a rise of serum P levels on the day of hCG administration was associated with a reduced live birth rate after day-5 fresh ET.

To evaluate the association between serum P levels on the day of hCG administration and pregnancy outcome in women undergoing controlled ovarian hyperstimulation, prevention of premature ovulation by GnRH analogues, and fresh ET after 5 days of embryo culture.
Retrospective, observational, cohort study.
Private IVF center.
A total of 2,555 women undergoing fresh ET on day 5 in 2,062 GnRH agonist and 493 GnRH antagonist cycles.
Main Outcome Measure(s):
Live birth rate.
Live birth rate in cycles with GnRH agonists was significantly lower in women with P levels ≥2.0 ng/mL (17.4%) on the day of hCG administration as compared with women with P levels
A rise of serum P levels ≥2.0 ng/mL on the day of hCG administration is associated with impaired early embryo implantation and reduced live birth rate in cycles with GnRH agonists after day-5 fresh ET.
