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, there are fe…

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…

ProblemA proportion of patients with unexplained recurrent implantation failure (uRIF) may have endometrial immune dysregulation amenable to treatment. Ultimpro (Matrice lab Innove, Paris, France) is an endometrial immunophenotype test whic…

BackgroundCongenital 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 po…

In this case report, we review a patient in whom ovarian reserve parameters increased significantly following treatment of uncontrolled diabetes. The patient is a previously healthy, lean 29-year-old woman in a same-sex relationship who was…

ObjectiveWomen 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 d…

OBJECTIVE: To assess the effect of endometrial thickness (EMT) on live birth rates (LBR) in women with endometrial lining between 7.0-9.9 mm. METHODS: This retrospective cohort study included women who underwent fresh and frozen embryo tran…

PurposeThe 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 cri…

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 …

PurposeTo 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 ho…

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…

BackgroundFollitropin 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 (IU…

PurposeTo evaluate the oocyte potential to develop to blastocyst in Rotterdam consensus PCOS in women with hyper-responses requiring freeze-all embryos.MethodsRetrospective, single-academic center, cohort study of 205 patients who underwent…

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

ObjectiveTo evaluate the endometrial histopathological profile of patients undergoing curettage and the association of the histopathological profile with the pregnancy outcome during the subsequent in-vitro fertilization (IVF) cycle.Methods…

PurposeTo assess obstetric outcomes and placental histology following intracytoplasmic sperm injection (ICSI), for non-male infertility.MethodsThis was a retrospective cohort of live born singleton deliveries after in vitro fertilization (I…

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…

PurposeTo evaluate the effect of the COVID-19 pandemic state on early, first-trimester pregnancies.MethodsA retrospective cohort study conducted at a university-affiliated fertility center in Montreal, Quebec, since the COVID-19 shut down, …

The prolonged lockdown of health services providing high-complexity fertility treatments -as currently recommended by many reproductive medicine entities- is detrimental for society as a whole, and infertility patients in particular. Global…

PurposeTo evaluate the effect of non-cavity-distorting intramural leiomyomas on the placental histopathology pattern and perinatal outcome in singleton live births resulting from in vitro fertilization treatment.MethodsThe study population …

OBJECTIVE: To determine whether 2 months of pretreatment with 5 mg of letrozole daily plus leuprolide acetate at 3.75 mg monthly in women with laparoscopically confirmed American Society of Reproductive Medicine stage I-II endometriosis imp…

ObjectiveTo compare the influence of dual suppression with the use of GnRH agonist plus aromatase inhibitor compared with suppression with the use of GnRH agonist alone or no suppression at all in patients with idiopathic recurrent implanta…
