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.
