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…

To evaluate the association between implementation of a standardized endocavitary sonography image-documentation protocol, developed in accordance with the International Deep Endometriosis Analysis (IDEA) consensus, and the diagnostic perfo…

BACKGROUND: This study evaluated the effects of different ovulation trigger strategies on pregnancy outcomes in letrozole-stimulated and modified natural frozen–thawed embryo transfer (L-FET and mNC-FET) cycles. METHODS: A total of 2053 eli…

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by chronic low-grade inflammation of the ovaries. This disorder of the immune microenvironment is closely related to abnormal follicular development and ovulation disorders. This…

Abstract Objectives This study investigated the fertilizing potential of leuprolide acetate in infertile patients with endometriosis (EMS). Methods This study included 116 patients with the EMS infertility, who were randomly divided into th…

BACKGROUND: The endometrial preparation of frozen embryo transfer cycle is to synchronize of endometrium and embryo under the condition of exogenous estrogen and progesterone drugs in HRT or follicle monitoring in NC. Estrogen and progester…

Ovarian endometrioma (OEM) remains a challenging manifestation of endometriosis, particularly in women with infertility, recurrent disease, or concern about ovarian reserve. Ultrasound-guided sclerotherapy has emerged as a minimally invasiv…

PURPOSE: To establish a diagnostic model combining contrast-enhanced ultrasound (CEUS), human epididymis protein 4 (HE4), and Ovarian-Adnexal Reporting and Data Systems (O-RADS) US v2022, verify its diagnostic efficacy, and compare it with …

OBJECTIVE: To study the MRI characteristics of adenomyosis in secondary infertility patients, and to analyze the factors affecting pregnancy after High-intensity focused ultrasound (HIFU). METHODS: Clinical data of 388 patients with adenom…

OBJECTIVE: This study aimed to analyze the effect of progesterone (P) levels on the human chorionic gonadotropin (hCG) trigger day and the progesterone on hCG day-to-basal progesterone (PhCG/Pbasal) ratio on pregnancy outcomes in patients w…

BACKGROUND: To compare in-vitro fertilization and embryo transfer (IVF-ET) pregnancy outcomes following endometrial polypectomy using either a manual mechanical hysteroscopic tissue resection device (mHTR) or traditional mechanical resectio…

BACKGROUND: Alarelin acetate, a synthetic gonadotropin-releasing hormone (GnRH) analogue, is widely used to manage endometriosis and hormone-sensitive malignancies. Although its safety profile is generally favorable, we report the first doc…

BACKGROUND: The global health crisis of coronavirus disease 2019 (COVID-19) continues to impact people of all age groups worldwide. Recent studies increasingly support that COVID-19 infection may affect reproductive function, causing subfer…

BACKGROUND: As women age, their ovarian follicle pool naturally declines. However, female germline stem cells (FGSCs) possess a unique ability to differentiate into oocytes and continuously self-renew, providing an effective means of delayi…

Background: Finding effective strategies and novel targets for reversing drug resistance is one of the major frontiers in hepatocellular carcinoma (HCC) research. Ferroptosis is participate in the malignant progression and drug resistance o…

BACKGROUND: High rates of infertility and pregnancy complications in patients with intrauterine adhesion (IUA) even after surgical repair may be associated with poor endometrial receptivity (ER). In our previous study, we found that changes…

INTRODUCTION: Ultrasound has become a routine method for endometrial receptivity (ER) evaluation. However, there is controversy over the independent evaluation values of various ultrasound indicators. Some researchers have designed multi-in…

STUDY OBJECTIVE: To investigate whether different timings of GnRH-a downregulation affected assisted reproductive outcomes in infertile women with moderate-to-severe intrauterine adhesions (IUAs) accompanied by adenomyosis. DESIGN: A retro…

Observational studies have previously reported an association between depression and certain female reproductive disorders. However, the causal relationships between depression and different types of female reproductive disorders remain unc…

Previous observational studies have suggested that anti-Müllerian hormone (AMH) and reproductive factors are linked to reduced bone mineral density (BMD) and an increased risk of osteoporosis (OP) in women. However, related studies are limi…

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…

BACKGROUND: To explore whether SARS-CoV-2 infection affects the pregnancy outcomes of assisted reproductive techniques (ART). METHODS: A prospective cohort study recruited patients for embryo transfer from December 01, 2022, to December 31…

OBJECTIVE: To clarify whether intrauterine adhesions (IUAs) affect endometrial receptivity (ER) on the day of ovulation and to compare patients with mild and moderate-severe adhesions. METHODS: This prospective cohort study included 592 in…

BACKGROUND: Chronic low-grade inflammation and ovarian germline stem cells (OGSCs) aging are important reasons for the decline of ovarian reserve function, resulting in ovarian aging and infertility. Regulation of chronic inflammation is ex…

BACKGROUND AND OBJECTIVES: Japanese women face many female-specific health problems in the workplace, especially menstruation-related issues, which can adversely affect their quality of life and productivity. This study aims to examine how …
