Female reproductive disorders influence women's physical and mental well-being, and the sustainability of the family. However, it is unclear whether lifestyle factors, including sedentary behaviors and physical activity, could impact them. …

PURPOSE: To investigate the impact of regressed endometrial hyperplasia (EH) on assisted reproductive technology outcomes, particularly in comparison with infertile women with a relatively normal endometrium. METHODS: This retrospective st…

Adenomyosis, characterized by clinical intractability, significantly impacts female fertility and life quality due to the absence of definitive diagnostic markers and effective treatment options. The invagination theory is a primary hypothe…

PURPOSE: To evaluate whether prior SARS-CoV-2 infection adversely affects live birth and perinatal outcomes following subsequent frozen-thawed embryo transfer (FET) and to further investigate whether the time interval between infection and …

Elevated lactate levels have been linked to poor prognosis in patients with acute pancreatitis (AP). Lactate-derived lactylation, a novel post-translational modification, has been implicated in various pathological processes by modulating g…

BACKGROUND: Adenomyosis is a chronic gynecological disorder characterized by the invasion of endometrial tissues into the myometrium of the uterus, with pathophysiology linked to chronic inflammation and metabolic dysregulation. However, th…

BACKGROUND: Preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) has been widely utilized to select euploid embryos in patients carrying balanced chromosomal rearrangements (BCRs) by chromosome copy number anal…

In this multicenter, non-inferiority, randomized trial, we randomly assigned 992 women undergoing in-vitro fertilization (IVF) with a good prognosis (aged 20-40, ≥3 transferrable cleavage-stage embryos) to strategies of blastocyst-stage (n …

PURPOSE: Together with ultrasound measurement of follicle size, serum estradiol (E2) provides guidance for controlled ovarian hyperstimulation (COH). However, during the COH process, some patients experience decreased serum E2 level, especi…

OBJECTIVE: The incidence of Polycystic Ovary Syndrome (PCOS) is increasing annually. This study aims to investigate the therapeutic mechanisms of Yikang Decoction (YKD) in the treatment of PCOS through the integration of GEO datasets, netwo…

Enhancing the effectiveness of platelet-rich plasma (PRP) for endometrial regeneration is challenging, due to its limited mechanical properties and burst release of growth factors. Here, we proposed an injectable interpenetrating dual-netwo…

CONTEXT: Abnormal endometrial extracellular matrix (ECM) remodeling compromises endometrial receptivity and diminishes the probability of a successful live birth. Serum amyloid A1 (SAA1), a modulator of inflammation, is elevated in the circ…

Objective: Recurrent implantation failure (RIF) is now disturbing numerous infertile couples accepting assisted reproductive technology (ART). And the endometrial factors are crucial causes of recurrent implantation failure. However, its me…

IMPORTANCE: Implantation failure remains a critical barrier to in vitro fertilization. Prednisone, as an immune-regulatory agent, is widely used to improve the probability of implantation and pregnancy, although the evidence for efficacy is…

BACKGROUND: Insulin resistance (IR) contributes to ovarian dysfunctions in polycystic ovarian syndrome (PCOS) patients. Serum amyloid A1 (SAA1) is an acute phase protein produced primarily by the liver in response to inflammation. In additi…

INTRODUCTION: Conventional intracytoplasmic sperm injection (ICSI) is a widely used treatment for couples with severe male infertility. However, there are controversies regarding the selection and the damage to gametes during the ICSI proce…

OBJECTIVE: Concern regarding the adverse impact of pretreatment of oral contraceptives (OC) prior to ovarian stimulation for in vitro fertilization (IVF) on pregnancy outcome has been debated. We investigated factors that may be associated …

Purpose: Serum concentrations of sex hormone binding globulin (SHBG), a glycated homodimeric plasma transport protein, correlate positively with the total number of follicles in women with infertility. However, the relationship between seru…

Embryo implantation rate remains an inefficient process in in vitro fertilization and embryo transfer (IVF-ET) cycles. The role long non-coding RNA (lncRNA) plays in embryo implantation remains unclear. We aimed to investigate the expressio…

Endometriosis is a common gynecological disease in which ovarian dysfunction can be an important cause of infertility. Elevated progesterone (P4) levels during the follicular phase is possibly associated with impaired oocyte quality and pre…

Endometriosis (EMS) is a common gynecological disease in women of reproductive age that causes dysmenorrhea, chronic pelvic pain and infertility, resulting in a major reduction in health-related quality of life. The incidence rate of EMS ha…

Objective To investigate the changes and clinical significance of Treg and Th17 cells in patients with ovarian endometrioma (OEM) pre- and post-laparoscopy. Methods 36 patients with OEM undergoing laparoscopic surgery and confirmed b…

BACKGROUND: Multiple pregnancies are one of the major safety concerns of in vitro fertilization (IVF) due to the increased risk of maternal and neonatal complications. Single embryo transfer is the most effective way to reduce the risk of m…

PURPOSE: The purpose of this study is to report two cases of monozygotic quadruplet and triplet pregnancies following single embryo transfer (ET). METHODS: A 29-year-old woman and a 34-year-old woman underwent ART treatment in two affiliat…
