ABSTRACT: This study aimed to investigate whether an early LH surge during controlled ovarian stimulation (COS) affects pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) undergoing assisted reproductive technology (ART) a…

PURPOSE: This study aimed to evaluate the pregnancy outcomes of frozen embryo transfer (FET) in patients with persistent chronic endometritis (PCE). METHODS: 186 patients were stratified into three groups: Cured CE (CCE), Cured Persistent …

Iron overload induces cellular stress and is implicated in diverse pathological conditions. Nevertheless, the epigenetic mechanisms governing mammalian cellular responses to iron overload remain poorly characterized. Using multi-omics profi…

In brief: We present the first single-cell transcriptomic atlas of follicular fluid from an ovarian endometrioma (OMA) patient, revealing a novel TCR+ macrophage subtype, aberrant granulosa cell developmental trajectories, immune dysregulat…

BACKGROUND: This study aims to identify the optimal dominant follicle size on the trigger day in patients with ovulatory dysfunction and unexplained infertility undergoing intrauterine insemination with letrozole (LE-IUI) cycles. METHODS: …

BACKGROUND: The treatment for recurrent pregnancy loss (RPL) has been addressed in international guidelines. However, limited studies have investigated the risk factors associated with pregnancy and live birth outcomes in patients with RPL …

Iron is essential for the health of reproductive system, and women with iron overload suffer from ovarian dysfunction and lack effective treatment in fertility preservation. However, the underlying mechanism of the detrimental effects of ir…

PURPOSE: This study aimed to develop a predictive tool for live birth in women with adenomyosis undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment. METHODS: A total of 424 patients with adenomyosis wh…

RESEARCH QUESTION: Do frozen embryo transfer (FET) cycles following long-term gonadotrophin-releasing hormone agonist (GnRHa) pretreatment have better pregnancy outcomes than fresh embryo transfer cycles with long or ultra-long GnRHa protoc…

Abstract Background There is few predictive tools for live birth in women with adenomyosis, which provide further personalized and clinically specific information related to individualized decisions making during IVF/ICSI treatment. Methods…

PURPOSE: To determine the impact of ovarian endometrioma per se on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. METHODS: This retrospective study was conducted using two groups. The endometrioma group consis…

OBJECTIVE: The objective of this retrospective cohort study was to explore the optimal range of the total progressive motile sperm count (TPMSC) for live birth in couples with varying infertility diagnosis undergoing intrauterine inseminati…

OBJECTIVE: This study aimed to compare the ultra-long gonadotropin-releasing hormone agonist (GnRH-a) protocol and the long GnRH-a protocol during in vitro fertilization (IVF) or intracytoplasmic sperm (ICSI) treatment on fertility outcomes…

STUDY QUESTION: Does an artificially induced FSH surge at the time of hCG trigger improve IVF/ICSI outcomes? SUMMARY ANSWER: An additional FSH bolus administered at the time of hCG trigger has no effect on clinical pregnancy rate, embryo q…

Objective To evaluate the impact of ovarian endometrioma without surgery on patients’ ovarian reserve and clinical pregnancy outcomes after control ovarian hypersimulation. Methods A total of 352 patients were included, who were perf…

INTRODUCTION: Endometriosis, the most common gynecological disorder, is a challenging disease observed in 20% - 40% of subfertile women. MATERIAL AND METHODS: 380 women were divided into four groups. Group A consisted of 176 women with pel…

Embryo implantation involves the intimate interaction between an implantation-competent blastocyst and a receptive uterus, which occurs in a limited time period known as the window of implantation. Emerging evidence shows that defects origi…

Extensive tissue remodeling occurs in the corpus luteum (CL) during both formation and luteolysis. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are believed to play pivotal roles in these processes. In the present st…

The expressions of vascular endothelial growth factor (VEGF) in rat ovarian follicles and corpus luteum (CL) during different stages of pregnancy and postpartum were investigated. In addition, the effect of tumor necrosis factor-alpha (TNF-…
