- Abstract
Our aim was to investigate the clinical significance of premature elevated progesterone levels in women with good ovarian response treated with long gonadotropin-releasing hormone agonist (GnRH-a) cycles and IVF. Premature elevated progesterone levels refer to a rise in serum progesterone levels on the day of human chorionic gonadotrophin (hCG) administration for final oocyte maturation above a threshold level, which is usually arbitrarily defined. This is a retrospective case study, which consists of 1,045 treatment cycles in women with low P/E2 [progesterone (ng/mL) × 1,000/estradiol (pg/mL)] on the day of hCG. Elevated P levels on the day of hCG administration were defined as >1.1 ng/mL. The data of the control group (≤1.1 ng/mL, n = 900 patients) were compared with those of the high P group (>1.1 ng/mL, n = 145). Compared with the control group, those in the high progesterone group had higher levels of estradiol on the day of hCG (3,143 vs. 2,382 pg/ml) ( p: 0.000) and higher numbers of MII oocytes (14.0 and 12.9) ( p: 0.001). The total number of embryos and the number of good-quality embryos transferred did not differ significantly between the groups. Implantation rate (18.1 vs. 24.4%) ( p: 0.008), and live birth rate (27.6 vs. 40%) ( p: 0.004), were significantly lower in patients with high progesterone levels. OR and 95% CI were 0.57 (0.39–0.84) for the live birth rate. In women stimulated with GnRHa and hMG/FSH for IVF, elevated serum progesterone levels on the day of hCG administration were associated with diminished implantation rates and live birth rates regardless of ovarian reserve.
