Abstract

Background: Premature progesterone rise (PPR) has long been implicated as contributing to implantation failure. Despite the use of gonadotropin-releasing hormone (GnRH) analogues, subtle increases in serum progesterone (P4) levels beyond a threshold progesterone concentration were observed on the day of trigger in controlled ovarian hyperstimulation cycles.

Aims: The purpose of the study was to evaluate the incidence of PPR on the day of trigger in conventional IVF/ICSI cycles and its impact on clinical pregnancy rate.

Settings and design: A total of 235 patients undergoing conventional IVF/IVF-ICSI by fresh embryo transfer cycles from January 2016 to December 2016 at the infertility unit of a tertiary care hospital were prospectively analyzed.

Material and methods: Patients included in the study were subjected to GnRH agonist long/antagonist protocol. Ovulation induction was given with rFSH and/or HMG in both the protocols. The cutoff for defining PPR was P4≥ 1.5 ng/ml, and an analysis of the role of P4on clinical pregnancy rate was performed. Statistical analysis was performed with the Statistical Package for the Social Sciences trial version 23.0 software for Windows and Primer software.

Results and conclusion: The overall clinical pregnancy rate per embryo transfer was 30.6%. The clinical pregnancy rate in the patients with P4 <1.5 ng/ml was significantly higher than those with elevated levels, P4≥ 1.5 ng/ml (33.3% vs. 12.9%; P = 0.037). Premature progesterone elevation in ART cycles is possibly associated with lower clinical pregnancy rates.

Keywords: Clinical pregnancy rate; controlled ovarian hyperstimulation; premature progesterone rise.
