PURPOSE: The purpose of this study was to determine the effects of intrauterine infusion of autologous blood cell derivative (ABCD) on endometrial thickness and pregnancy outcomes in a group of patients who underwent IVF with recurrent impl…

PURPOSE: To evaluate the embryological and pregnancy outcomes of women who failed in their first IVF treatment if they attempted a second cycle. METHODS: For evaluating the embryological outcomes, the study cohort included 1,227 women who …

PURPOSE: To determine correlations between chemicals in follicular fluid (FF) and follicular reproductive hormone levels. METHODS: The analysis was part of a larger cohort study to determine associations between exposure to EDCs and in vit…

PURPOSE: To investigate whether the transcriptome profile differs between progesterone-treated infertile and fertile endometrial organoids. METHODS: Endometrial biopsies were obtained from 14 infertile and seven fertile women, after which …

PURPOSE: Zygotes with 2.1 pronuclei (2.1PN) present with two normal-sized pronuclei, and an additional smaller pronucleus, that is approximately smaller than two thirds the size of a normal pronucleus. It remains unclear whether the additio…

The current article is a literature review aiming to provide an overview of the existing knowledge on the association between telomere length and telomerase activity and in vitro fertilization. Recently, telomeres have been used as an effec…

PURPOSE: Endometriosis (EMS) is a relatively common gynecological disorder and almost fifty percent of women with EMS suffer from infertility. There are few treatment options for endometriosis, and often recurrences occur following surgery …

PURPOSE: Ovarian stimulation with gonadotropins is crucial for obtaining mature oocytes for in vitro fertilization (IVF). Determining the optimal gonadotropin dosage is essential for maximizing its effectiveness. Our study aimed to develop …

OBJECTIVE: In vitro fertilization-embryo transfer (IVF-ET) is a widely used treatment for infertility, with oocyte maturation and quality having a significant impact on oocyte fertilization, embryo development, and fetal growth. Mitochondri…

PURPOSE: This position statement by the Italian Society of Fertility and Sterility and Reproductive Medicine (SIFES-MR) aims to establish an optimal framework for fertility preservation outside the standard before oncological therapies. Key…

PURPOSE: There is an unclear relationship between estradiol levels and fresh embryo transfer (ET) outcomes. We determined the relationship between estradiol on the day of trigger, in fresh ET cycles without premature progesterone elevation,…

PURPOSE: When resecting endometriomas with the stripping technique, in the majority of cases, a thin line of adjacent ovarian cortex is attached to the endometrioma. In this study, we performed histological analysis to determine (antral) fo…

PURPOSE: To analyze the fertilization, developmental, and pregnancy potentials in oocytes with narrow perivitelline space. METHODS: Perivitelline space (PVS) of oocytes was evaluated at the time of ICSI, and those without sufficient PVS we…

PURPOSE: This study aims to evaluate whether the clinical outcomes of cycles with frozen embryo transfer (FET) in hormonal replacement treatment supplemented with dydrogesterone (DYD) following detection of low circulating levels of progest…

PURPOSE: To evaluate the efficacy of magnetic-activated cell sorting (MACS) or testicular sperm aspiration (TESA) to improve reproductive outcomes in cases with elevated sperm DNA fragmentation undergoing assisted reproduction. METHODS: Th…

PURPOSE: To investigate the impact of heterogeneity in patient indications or insemination protocols on neonatal outcomes of singletons following early rescue ICSI (rICSI) treatments. METHODS: A retrospective study was conducted. Propensit…

PURPOSE: Patients with polycystic ovarian morphology (PCOM) make up 20% cases for assisted reproductive technology (ART). Folliculogenesis is impaired in PCOS. Signaling molecules are involved in follicle development. Dysregulations of intr…

PURPOSE: To explore if a day 7 blastocyst is predictive of the reproductive potential of sibling day 5 or day 6 blastocysts? METHODS: Retrospective cohort of autologous frozen embryo transfers (FET), February 2019 to April 2022. Cycles div…

Female fertility preservation is a rapidly growing field in medicine. Oocyte cryopreservation and assisted reproductive technique with vitrified-warmed oocytes have been successful with in vivo matured oocytes after conventional ovarian sti…

PURPOSE: To identify potential biomarkers and the molecular mechanisms associated with repeated implantation failure (RIF), three microarray datasets, GSE71331 (lncRNA + mRNA), GSE111974 (lncRNA + mRNA), and GSE71332 (miRNA), were retrieved…

PURPOSE: To determine whether patients with Marfan syndrome are at an increased risk for reproductive disorders. METHODS: This retrospective cohort study was conducted using the US collaborative network on the TriNetX research network of h…

PURPOSE: In vitro fertilization (IVF) is associated with abnormal trophoblast invasion and resultant decreased levels of circulating placental biomarkers such as placental growth factor (PlGF). Our objective was to evaluate maternal serum l…

PURPOSE: Gene expression analysis of the endometrium has been shown to be a useful approach for identifying the molecular signatures and pathways involved in recurrent implantation failure (RIF). Nevertheless, individual studies have limita…

OBJECTIVE: The objective of this study was to investigate the role of phase separation-related genes in the development of endometriosis (EMs) and to identify potential characteristic genes associated with the condition. METHODS: We used G…
