A comparative analysis of progestin-primed ovarian stimulation versus GnRH antagonists protocols pertaining to stimulation parameters and embryological outcomes in patients with endometrioma
Frontiers in endocrinology ·doi:10.3389/fendo.2025.1492293

RESEARCH QUESTION: Do embryo parameters and live birth rates differ between patients with endometrioma undergoing a freeze-all strategy using either GnRH antagonists or progestin-primed ovarian stimulation (PPOS)? DESIGN: This retrospectiv…

Individualized luteal phase support in frozen-thawed embryo transfer after intramuscular progesterone administration might rectify live birth rate.
Frontiers in endocrinology ·doi:10.3389/fendo.2024.1412185

BackgroundThe serum P concentrations are suggested to have an impact on pregnancy outcome. However there is no consensus about the optimal progesterone cut-off during the luteal phase. Few studies evaluated the effectiveness of a "rescue pr…
