Conventional in vitro fertilization (IVF) outcome prediction is limited by static, single-endpoint analyses. We aimed to overcome this by using a multistate model to dissect the stage-specific and, crucially, the non-linear influence of end…

Data sharing is not applicable to this article as no datasets were generated or analyzed during the current study. Figure S1. Ultrasound images of the pelvis. (A) The uterus is enlarged, measuring approximately 59 × 57 × 60 mm, with heterog…

PURPOSE: Embryo cryopreservation plays an essential role in assisted reproductive technology (ART). Vitrification has gradually replaced slow-freezing of embryos. In this study we investigated the effects of embryo vitrification on neonatal…

BACKGROUND: Optimal cytoreductive surgery and platinum sensitivity are critical prognostic factors in advanced epithelial ovarian cancer (EOC). However, the preoperative value of routinely available serum biomarkers in predicting surgical o…

BACKGROUND: Adenomyosis (AM) is a common gynecological disorder in reproductive-age women, with impaired endometrial receptivity as a key contributor to infertility. However, a comprehensive single-cell atlas of the eutopic endometrium duri…

ObjectiveTo evaluate whether vitamin D supplementation improves live birth rates in women with polycystic ovary syndrome undergoing in vitro fertilisation.DesignMulticentre, double blind, placebo controlled, randomised clinical trial.Settin…

BACKGROUND: The success of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) in endometriosis patients varies widely, and predicting the likelihood of achieving a live birth remains a clinical challenge. This study aims t…

Adenomyosis is characterized by the infiltration of endometrial glands and stroma into the myometrium which affects about 35% women at reproductive age. Women affected by adenomyosis always experience issues such as defective decidualizatio…

Exposure to phthalates is common and difficult to avoid. However, intake of long-chain n-3 polyunsaturated fatty acids (n3PUFAs) may ameliorate negative effects on ovarian reserve by exposure to phthalates as both are involved in key proces…

BACKGROUND: Female reproductive aging remains irreversible. More evidence is needed on how polyunsaturated fatty acids (PUFAs) affect the female reproductive lifespan. OBJECTIVES: To identify and validate specific PUFAs that can influence …

Premature ovarian insufficiency (POI) is a diverse form of female infertility characterized by a decline in ovarian function before the age of 40. Melatonin (MT) is a potential clinical treatment for restoring or safeguarding ovarian functi…

OBJECTIVE: To investigate the association between infertility and the incidence of invasive cancer. DESIGN: Prospective cohort study (1989-2015). SETTING: Not applicable. PATIENT(S): A total of 103,080 women aged 25-42 years in the Nurse…

BACKGROUND: Women are at greater risk than men of developing chronic inflammatory conditions and "long COVID." However, few gynecologic health risk factors for long COVID-19 have been identified. Endometriosis is a common gynecologic disord…

BACKGROUND: TGFβ1 is a major profibrotic mediator in chronic kidney disease (CKD). Its direct inhibition, however, is limited by adverse effects. Inhibition of activins, also members of the TGFβ superfamily, blocks TGFβ1 profibrotic effects…

Abstract Background: Endometriosis can affect the systemic metabolic indicators, including body mass index, glucose metabolism and lipid metabolism, while the association between metabolic indexes and the occurrence and ART outcome of endom…

BACKGROUND: Endometriosis is associated with systemic metabolic indicators, including body mass index (BMI), glucose metabolism and lipid metabolism, while the association between metabolic indexes and the occurrence and assisted reproducti…

Intrauterine adhesions (IUA), which is characterized by endometrial fibrosis, continue to be the most common cause of uterine infertility globally. Our work revealed that 3 fibrotic progression markers (Vimentin, COL5A2, and COL1A1) were si…

Increasing evidences showed that ovulatory dysfunction, possibly caused by luteinized unruptured follicular follicle syndrome (LUFS), is one of the reasons for endometriosis-related infertility. The present study was conducted to explore th…

This is a case report of a nulliparous young woman who suffered from prolonged menstruation and infertility for 1 year. Magnetic resonance imaging and a transvaginal ultrasound examination revealed cervical endometriosis. Treatment with a g…

Wound healing is a tandem process involving inflammation, proliferation, and remodeling, through which damage is repaired and ultimately scar tissue is formed. This process mainly relies on the complex and extensive interaction of growth fa…

BACKGROUND: The basal follicle stimulating hormone (FSH)/luteinizing hormone (LH) ratio is a useful predictor of ovarian response. In this study, we investigated whether the FSH/LH ratios during the entire controlled ovarian stimulation (CO…

Female fertility declines with age, and this natural variation culminates in reproductive senescence. Human follicular fluids are rich in low-molecular weight metabolites which are responsible for the maturation of oocytes. The metabolomic …

BACKGROUND: Premature ovarian insufficiency (POI) is a refractory disease that seriously affects the reproductive health of women and is increasing in incidence and prevalence globally. There is enormous demand to improve fertility in women…
