Elevated progesterone in GnRH agonist down regulated in vitro fertilisation (IVFICSI) cycles reduces live birth rates but not embryo quality.

Abstract

OBJECTIVE
To assess the impact of pre-hCG elevated progesterone on live birth outcomes during GnRH agonist long down regulated protocol assisted reproduction cycles.
DESIGN
Retrospective cohort study.
SETTING
Single Centre Private IVF Clinic.
PATIENTS
A total of 582 consecutive cycles of IVF/ICSI in 2003.
INTERVENTIONS
All patients underwent a long down-regulation protocol, controlled ovarian stimulation and IVF/ICSI. Serum progesterone concentrations were measured just prior to HCG administration. 253 patients were followed to 2009 for outcomes of their frozen embryo cycles.
MAIN OUTCOME MEASURE
Live birth rate in fresh and frozen cycles.
RESULTS
Patients in the upper quartile pre-hCG progesterone concentration (≥ 5.4 pmol/L) had a higher final estradiol level, more oocytes collected and more usable embryos, when compared to those with lower quartiles. They also had lower live birth rates per cycle started (21.9% vs. 15%, P < 0.05). However, live birth rates from frozen embryo cycles were not significantly different between the groups.
CONCLUSIONS
Pre-hCG progesterone elevation leads to lower live birth rates in stimulated IVF cycles. Live birth rates achieved with frozen embryos in the high progesterone cycles suggest, that pre-hCG progesterone elevation negatively affects endometrial receptivity without adversely affecting embryo quality.
