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…
PURPOSE: To investigate any correlation between the outcomes of the first euploid frozen-thawed blastocyst embryo transfer (FBT) and the subsequent euploid FBT derived from sibling oocytes. METHODS: This retrospective study analyzed data f…
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…
OBJECTIVE: To compare the ongoing pregnancy rates (OPRs) for subcutaneous progesterone (SC-P) to intramuscular progesterone (IM-P) in hormone replacement therapy used in frozen embryo transfer (FET) cycles. DESIGN: Prospective nonrandomize…
BACKGROUND: Is freeze-all strategy effective in terms of cumulative live birth rates (CLBRs) in all patients? METHODS: This retrospective single-center study analyzed the CLBRs of 2523 patients undergoing fresh or electively frozen blastoc…
BACKGROUND: To assess the predictive value of patient characteristics, controlled ovarian stimulation and embryological parameters on the live birth outcome of single euploid frozen-warmed blastocyst transfer (FBT). METHODS: This was a ret…
The aim of this study was to evaluate the possible effects of endometriosis on early embryo development, by comparing the morphokinetic development of embryos obtained from women with clinically confirmed endometriosis with the ones obtaine…
