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…

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants with potential reproductive toxicity, yet their profiles in follicular fluid and impacts on human fertility remain unclear. Given the importance of diet as…

Unexplained recurrent pregnancy loss (URPL) represents a prevalent obstetric complication and remains a challenging condition with poorly understood genetic etiology. Through whole-exome sequencing of 94 URPL patients, we identified enriche…

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: …

Ovarian endometrioma (OMA), an estrogen-dependent gynecological disorder, is characterized by the presence of abundant free iron resulting from recurrent hemorrhage of endometrial cells within the cyst, which adversely affects ovarian funct…

PURPOSE: To elucidatethe epigenetic alteration associated with impaired oogenesis in endometrioma using multi-omic approaches. METHODS: ATAC-seq was performed on the granulosa cells (GCs) of 6 patients (3 with endometrioma and 3 without). …

BACKGROUND: This study focuses on the risk of early miscarriage in patients undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). These patients commonly experience heightened stress levels and may discontinue …

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…

BACKGROUND: To compare the efficacy and safety of follitropin delta in its individualized fixed-dose regimen with follitropin alfa in a conventional adjustable dosing regimen in Chinese women.  METHODS: This was a subgroup analysis of the r…

Adenomyosis is an estrogen-dependent gynecological disorder. The abnormal migration and invasion of the eutopic endometrium is thought to be the primary role in the pathogenesis of adenomyosis. However, the exact underlying mechanism remain…

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…

BACKGROUND: Emerging data suggest a significant association between migraine and endometriosis, however the relationship between migraine and endometriosis severity or adenomyosis is unclear. Our objectives were to explore the relationship …

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…

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…

BACKGROUND: Endometriosis is a common disease. The most widely used staging system of endometriosis is the revised American Fertility Society classification (r-AFS classification) which has limited predictive ability for pregnancy after sur…

OBJECTIVE: Appropriate dosage of the long-acting depot gonadotrophin releasing hormone (GnRH) agonist has not been determined in long protocol for IVF, and one-third-dose depot triptorelin was compared with half-dose in a luteal long protoc…
