Progesterone level at oocyte retrieval predicts in vitro fertilization success in a short antagonist protocol A prospective cohort study

Progesterone (P) level at oocyte retrieval was inversely associated with pregnancy rates: as P levels increased, pregnancy rates decreased. The odds ratio for nonpregnancy was clinically significant when P was 12 ng/mL.

Abstract

Objective:

To evaluate the distribution of P levels on the day of oocyte retrieval as it relates to pregnancy outcome in an antagonist protocol, which may be at higher risk for elevated P levels.

Design:

Prospective cohort study.

Setting:

Academic IVF center.

Patient(s):

One hundred eighty-six women undergoing controlled ovarian hyperstimulation with an antagonist protocol.

Intervention(s):

None.

Main Outcome Measure(s):

Implantation, pregnancy, and spontaneous abortion rates were collected.

Result(s):

Implantation rate (positive hCG 14 days after ET) and pregnancy rate were significantly higher when the P level was

Conclusion(s):

Elevated P on the day of oocyte retrieval is associated with significantly lower implantation and ongoing pregnancy rates. This is the first study to date to both uncover the distribution of P on the day of oocyte retrieval in an antagonist cycle and determine the impact an elevation may have on pregnancy outcome.
