UNLABELLED: Introduction: Investigation of the number of oocytes recovered from different ovarian stimulation (OS) protocols is essential, as oocyte number is positively associated with the number of good-quality embryos obtained; however, …

Letrozole and other aromatase inhibitors are increasingly recognized as first-line ovulation induction (OI) medications, offering an efficient and physiologic approach to ovarian stimulation that enhances outcomes in reproductive medicine. …

OBJECTIVE: To assess the adequate ovarian follicular development and oocyte recovery between ovarian potential (antral follicle count [AFC]) before the start of ovarian stimulation (OS) and oocyte quantity and quality at oocyte retrieval. A…

Background: Despite significant advances in assisted reproductive technology (ART), disparities in clinical outcomes persist. While patient-related factors are well-studied, the role of partner ethnicity remains understudied. We hypothesize…

BACKGROUND: Congenital uterine anomalies are associated with adverse reproductive outcomes, yet the impact of the arcuate uterus remains unclear due to limited sample sizes and inconsistent findings in previous studies. We utilized a large …

OBJECTIVE: Women are often concerned about the absolute quantity and quality of sperm in a thawed donor sample at the time of intrauterine insemination (IUI). The aim of this study was to determine how the total motile sperm count (TMSC) of…

OBJECTIVE: To assess the influence of basal serum levels of luteinizing hormone (LH), total testosterone (TT), and free testosterone (FT) on in vitro fertilization (IVF) success rates in patients with polycystic ovary syndrome (PCOS). MATE…

PURPOSE: The purpose of this study is to investigate the impact of daily follicle-stimulating-hormone (FSH) dose on the likelihood of suboptimal response to ovarian stimulation (OS) for in vitro fertilization (IVF) according to POSEIDON's c…

The effectiveness of intravenous immunoglobulin (IVIg) for patients with unexplained recurrent implantation failure (uRIF) remains debated. We retrospectively analysed outcomes of uRIF patients treated with IVIg compared to a separate contr…

BACKGROUND: Currently, there is no consensus on the optimal management of women with low prognosis in ART. In this Delphi consensus, a panel of international experts provided real-world clinical perspectives on a series of literature-suppor…

PURPOSE: PCOS and endometriosis are independent risk factors for perinatal outcomes. Little research has evaluated the concomitant effects of these conditions, nor have studies been conducted on a population database. We sought to identify …

PURPOSE: To determine the risk of not being a poor responder in ovarian stimulation (OS) for in vitro fertilization (IVF) when ovarian reserve markers are discordant-one falling within Poseidon's criteria normal range (e.g., anti-Müllerian …

BACKGROUND: This study aims to determine whether pre or post-processing semen parameters obtained during intrauterine insemination (IUI) predict pregnancy when controlling for confounding effects. MATERIALS AND METHODS: A prospective cohor…

OBJECTIVE: To assess obstetric outcomes and placental findings in pregnancies attained by in vitro fertilization (IVF) in patients with diminished ovarian reserve (DOR). DESIGN: Retrospective cohort study. SETTING: University-affiliated t…

BACKGROUND: Follitropin Delta (FD) is indicated exclusively for in-vitro fertilization however, being a gonadotropin it could be used for other purposes. A dosing algorithm exists for FD and IVF but is needed for intrauterine insemination (…

Abstract Study question Does adenomyosis impact reproductive and neonatal outcomes? Summary answer Adenomyosis increases risk of infertility and pregnancy/delivery complications. Increased surveillance may aid in prevention and/or decreasin…

PURPOSE: To evaluate the oocyte potential to develop to blastocyst in Rotterdam consensus PCOS in women with hyper-responses requiring freeze-all embryos. METHODS: Retrospective, single-academic center, cohort study of 205 patients who und…

PURPOSE: To assess perinatal outcomes and placental findings in in vitro fertilization (IVF) patients with previous recurrent pregnancy loss (RPL). METHODS: This was a retrospective cohort of live singleton births following IVF at a single…

Abstract Study question Does endometriosis have an effect on the placental histopathology patterns in singleton live births resulting from in-vitro fertilization? Summary answer Endometriosis is associated with acute chorioamnionitis, place…

PURPOSE: To assess obstetric outcomes and placental histology following intracytoplasmic sperm injection (ICSI), for non-male infertility. METHODS: This was a retrospective cohort of live born singleton deliveries after in vitro fertilizat…

OBJECTIVE: Incarcerated uterus occurs at a rate of 1:3000 pregnancies. Previous studies focused on risk factors and management options, providing limited information about pregnancy outcomes. This study evaluates the effect of incarcerated …

RESEARCH QUESTION: Does endometriosis have an effect on the placental histopathology pattern and perinatal outcome in singleton live births resulting from IVF treatment? DESIGN: Retrospective cohort study evaluating the data on all live bi…
