BACKGROUND: Sperm DNA fragmentation index (DFI) has emerged as a potential marker of male fertility, but its clinical value in assisted reproductive technology (ART) remains debated. This study aimed to investigate the association between s…

PURPOSE: To investigate whether controlled ovarian stimulation (COS), as part of assisted reproductive technology (ART), accelerates the progression of BI-RADS categories. METHODS: This was a single-center, retrospective, propensity score …

OBJECTIVE: This study aims to evaluate the role of MRI-guided hysteroscopic one-step precise resection in diagnosing suspected myometrial invasion (MI) of endometrial cancer (EC) in patients desiring fertility preservation and to analyze th…

PURPOSE: Although observational studies suggest a link between socioeconomic status (SES) and hormone-related gynecologic diseases, the causal direction and mediating mechanisms remain unclear. This study aims to explore the causal relation…

OBJECTIVE: This study aimed to explore the feasibility and clinical effects of a novel hysteroscopic levonorgestrel-releasing intrauterine system (LNG-IUS) non-suture fixation at the uterine fundus. METHODS: From October 2023 to July 2024,…

AIM: Polycystic ovary syndrome (PCOS) is a common endocrine disorder with high incidence. It has been reported that patients with PCOS are at great risk of developing endometrial cancer (EC). Our study was aimed to analyze the shared gene s…

PURPOSE: This study was designed to evaluate the effects of dual trigger (GnRH agonist and hCG) compared with hCG trigger alone on oocyte quality, embryo development, and pregnancy outcomes in elderly women (aged≥35 years) who underwent IVF…

BACKGROUND: In our previous investigation, we revealed a significant increase in the expression of microRNA-6881-3p (miR-6881-3p) in follicular fluid granulosa cells (GCs) from women with diminished ovarian reserve (DOR) compared to those w…

INTRODUCTION: The relationships between the outcome of frozen-thaw embryo transfer (FET) cycle and endometrial compaction were not quite consistent. OBJECTIVE: To analyze the relationship between the outcome of FET cycle and endometrial co…

BACKGROUND: Surgery in elder patients with intermural fibroids delays pregnancy, and GnRH-a can shrink uterine fibroids to a certain extent; therefore, for geriatric patients with fibroids, determining whether GnRH-a pretreatment before fro…

Introduction: This study aimed to compare the pregnancy outcomes of different endometrial preparation protocols in patients with adenomyosis and thin endometrium during frozen embryo transfer. Methods: The study, which was conducted at the …

OBJECTIVE: This retrospective study aimed to explore whether puncturing and aspirating asynchronized large follicles during long GnRH-a protocol COH impacted IVF-ET outcomes. METHODS: A total of 180 patients with asynchronized follicles du…

PURPOSE: The purpose of the study was whether endometriosis influences IVF/ICSI and subsequent pregnancy and obstetric outcomes. METHODS: Searches were performed on PubMed, EMBASE, Medline, and Web of Science. Most of the included studies …

BACKGROUND: Gonadotropin-releasing hormone antagonist(GnRH-ant) has been shown to have a negative effect on endometrial receptivity. Therefore, the use of lower doses of GnRH-ant during controlled ovarian stimulation (COS) may improve endom…

Many undergoing in vitro fertilization-embryo transfer (IVF-ET) procedures treatments have been tried for older infertile patients, but still can not reverse the aging effect on oocyte, and infertility treatment is expensive, even for peopl…

BACKGROUND: The tumour microenvironment conferred by mesenchymal stem cells (MSCs) plays a key role in tumour development and progression. We previously determined that platelet-activating factor receptor (PAFR) was overexpressed in ovarian…

Background—According to extensive epidemiological data, infertility is associated with increased ovarian cancer risk. Previous studies showed that both women with infertility and those with ovarian cancer have autoantibodies to ovarian anti…

Abstract Epidemiological studies show women with infertility have increased ovarian cancer (OvCa) risk, but biomarkers indicating which women are at increased risk are unavailable. We showed autoantibodies (Abs) are associated with infertil…

BACKGROUND: According to extensive epidemiologic data, infertility is associated with increased ovarian cancer risk. Previous studies showed that both women with infertility and those with ovarian cancer have autoantibodies to ovarian antig…

OBJECTIVE: To identify ovarian autoantigens associated with ovarian autoantibodies. DESIGN: Hypothesis-generating prospective study. SETTING: Urban infertility referral centers and academic research institution. PATIENT(S): Seventy-four …

OBJECTIVE: This study was undertaken to determine the outcomes of hysterectomy with and without conservation of the ovaries. STUDY DESIGN: Data were collected prospectively for 3 years from 257 women undergoing hysterectomy (group 1) and 5…
