PURPOSE: To determine whether a selected set of mRNA biomarkers expressed in individual cumulus granulosa cell (CC) masses show association with oocyte developmental competence, embryo ploidy status, and embryo outcomes. METHODS: This pros…

PURPOSE: Clinical pregnancy rate after IVF with eSET stagnates between 30 and 40%. In order to increase pregnancy and live birth rates, multiple embryo transfer is still common practice. Providing additional non-invasive tools to choose the…

PURPOSE: To assess the effect of assisted hatching (AH) on live birth rate (LBR) in first cycle, fresh in vitro fertilization (IVF) in good and poor prognosis patients. METHODS: Retrospective cohort using cycles reported to the Society for…

PURPOSE: To analyze the pregnancy outcomes of IVF patients presenting eubiotic or dysbiotic endometrium at the time of embryo transfer and to analyze what bacterial profiles are suitable for embryo implantation. METHODS: Ninety-nine IVF pa…

PURPOSE: To investigate whether unexplained infertility at a young age demonstrates manifestations of decreased ovarian reserve. METHODS: A total of 100 women were divided into two equally sized groups. The study group comprised women aged…

PURPOSE: Implantation failure is a major limiting factor of successful in vitro fertilization (IVF). The objective of this study was to determine if endometrial mechanical stimulation (EMS) by endometrial biopsy in the luteal phase of the c…

OBJECTIVES: Management options for PCOS, as the most prevalent endocrine disorder in women of reproductive age, using natural supplements have a high priority for physicians, especially based on the etiological pathways. Therefore, this stu…

PURPOSE: To investigate the impact of symptomatic and surgically confirmed endometriosis on ovarian sensitivity index (OSI) and cumulative live-birth rates (LBR) using predominantly single embryo transfer (SET). METHODS: Cross-sectional ca…

PURPOSE: Despite the growing body of research implying an impact of in vitro fertilization (IVF) on imprinted genes and epigenetics, few studies have examined the effects of underlying subfertility or prenatal stress on epigenetics, particu…

Extracellular vesicles are lipoproteinaceous membrane-enclosed nanometer-sized structures produced by cells and are thought to mediate cellular communications. Loaded with a specific set of miRNA and protein depending on their tissue of ori…

PURPOSE: Hormonal stimulation prior to IVF influences the ovarian environment and therefore impacts oocytes and subsequent embryo quality. Not every patient has the same response to the same treatment and many fail for unknown reasons. Know…

PURPOSE: Endometriosis is a gynecological disease that causes the uterine lining to appear in other organs outside the uterus. As DNA methylation has an important role in this disorder, its profiling can reveal new information to improve th…

PURPOSE: Pre-pregnancy and post-delivery hospitalizations were compared as markers for health among women who conceived using assisted reproductive technology (ART), non-ART medically assisted reproduction (MAR), no treatment (unassisted su…

PURPOSE: To evaluate whether ICSI offers any benefit compared with IVF in different ovarian response categories in case of non-male factor infertility. METHODS: This is a retrospective multicenter analysis using individual patient data, co…

PURPOSE: To compare in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) in regard to post-fertilization development and outcome with the purpose of ascertaining the most effective fertilization method for assisted repr…

PURPOSE: To identify biomarkers that prospectively predict IVF cycle cancellation. METHODS: In this prospective study, sera were obtained prior to any intervention, from women about to undergo an IVF cycle. The sera were assayed by ELISA f…

OBJECTIVE: To determine whether younger oocyte donor age is associated with better outcomes after in vitro fertilization (IVF) compared with older oocyte donor age. DESIGN: A retrospective cohort study. SETTING: Large academically affilia…

PURPOSE: Reactive oxygen species (ROS) are thought to play a critical role in the success of IVF. The relationships between oxidative stress parameters in culture media and IVF outcomes have not been extensively investigated. The objective …

OBJECTIVES: To analyze in detail the fatty acid (FA) composition of follicular fluid (FF) from two-sized follicles at oocyte retrieval and to determine associations of the FAs from large follicles with the woman's age and the response to ov…

PURPOSE: To assess the effect of body mass index (BMI) on morphokinetic parameters of human embryos evaluated with time-lapse technology during in vitro culture. METHODS: A retrospective analysis of ART cycles utilizing time-lapse technolo…

PURPOSE: To evaluate the effect of medical or surgical treatment prior to embryo transfer in women with elevated endometrial BCL6 expression and suspected endometriosis in a prospective, cohort study design at a university-associated infert…

PURPOSE: To identify the disease-causing gene in a family with female infertility and fertilization failure. METHODS: Whole-exome sequencing and Sanger sequencing were used to identify the disease-causing gene in a female with infertility …

PURPOSE: To report the effects of blastocyst stage aneuploidy testing on clinical, gestational, and neonatal outcomes for patients of advanced maternal age undergoing IVF. METHODS: This is a single-center observational-cohort study with 2 …

PURPOSE: Primary ovarian insufficiency (POI) represents ovarian dysfunction related to very early aging of the ovaries. While the cause of POI in a majority of clinical cases remains undefined, autoimmunity is responsible for approximately …

PURPOSE: Controlled ovarian stimulation is a fundamental part of a successful assisted reproduction treatment, and recognizing patients at risk of a poor response allows the development of targeted research to propose new treatment strategi…
