OBJECTIVE To compare cycle outcomes after scheduling with the standard long protocol versus the use of oral contraceptive pills (OCPs) in patients undergoing GnRH antagonist cycles. DESIGN Prospective, randomized, controlled trial. SETTING University-affiliated private assisted reproduction center. PATIENT(S) Regularly cycling women aged ≤38 years(More)
BACKGROUND There is a growing consensus that ovarian endometriomas should not be systematically removed in women selected for IVF. However, some recent evidence suggested that the presence of these cysts may negatively affect the course of pregnancy. METHODS We set up a multicenter retrospective cohort study, including two infertility units. We analyzed(More)
BACKGROUND Both oral contraceptive pills (OCPs) and estradiol (E2) valerate have been used to schedule gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization (IVF) cycles and, consequently, laboratory activities. However, there are no studies comparing treatment outcomes directly between these two pretreatment methods. This randomized(More)
OBJECTIVE To use microarray technology to analyze endometrial gene expression after gonadotropin-releasing hormone agonist (GnRH-a) triggering with four different protocols of luteal support in comparison with results obtained after a human chorionic gonadotropin (hCG) trigger. DESIGN Prospective, randomized, controlled trial. SETTING(More)
OBJECTIVE To evaluate IVF outcome in women with unoperated bilateral endometriomas. DESIGN Multicenter retrospective cohort study. SETTINGS Two infertility units. PATIENT(S) Thirty-nine women with bilateral endometriomas matched with 78 unexposed control subjects. INTERVENTION(S) Analysis of data from patients who underwent in vitro fertilization(More)
STUDY QUESTION Does the combined oral contraceptive pill (COCP) change endometrial gene expression when used for cycle programming? SUMMARY ANSWER COCP used for scheduling purposes does not have a significant impact on endometrial gene expression related to endometrial receptivity. WHAT IS KNOWN ALREADY Controversy exists around COCP pretreatment for(More)
