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…
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…
Purpose: The existing literature is scarce regarding outcomes of fresh vs frozen embryo blastocyst transfers in women with endometrioma. The goal of the study was to compare outcomes between fresh and frozen blastocyst transfers (fresh-BT v…
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…
This study compared early pregnancy losses (termination of pregnancy before 12 weeks of gestation, EPL) among conceptions achieved by ICSI according to the type of GnRH analogue for ovarian stimulation. Only singleton gestations (2,184) and…
BACKGROUND: We evaluated the impact of using ICSI for assisted fertilization on first trimester survival rates of singleton gestations among an unselected infertile population. METHODS: The 1244 singleton gestations achieved by ICSI were s…
