Our study aimed to explore the mechanisms underlying abnormal angiogenesis in adenomyosis (AM). Endometria of internal adenomyosis (AM-in) and external adenomyosis (AM-ex) were collected for single-cell RNA-sequencing. Cells showing consist…

Introduction: Endometriosis is a benign gynecologic condition affecting ∼10% of reproductive-age women and involves the bowel in up to 12% of cases, mainly the rectosigmoid. Symptoms like dyschezia, constipation, dyspareunia, bloating, and …

BACKGROUND: To validate previous age subgrouping methods and provide an optimal age reference for women planning to delay in vitro fertilization (IVF). METHODS: From July 2014 to March 2018, 3012 patients that received IVF/intracytoplasmic…

Endometriosis has a detrimental effect on oocyte quality, and ovarian endometriosis (OEM) and peritoneal endometriosis (PEM) may have different effects on female fertility. Therefore, we conducted a study to explore the circular RNA (circRN…

To explore potential biomarkers indicating endometriosis (EM). A proteomics method and combined quantitative transcriptomics were adopted to highlight markers in the EM. Venn analysis was used to integrate the ribonucleic acid sequencing (R…

OBJECTIVE: To explore potential biomarkers indicating endometriosis (EM). MATERIALS AND METHODS: A proteomics method and combined quantitative transcriptomics were adopted to highlight markers in the EM. Venn analysis was used to integrate…

ART is an important treatment method for infertile patients with endometriosis. However, the effects of endometriosis on embryo quality and endometrial receptivity remain unclear. Thus, we aimed to simultaneously investigate the impact of e…

Background: Uterine malformations can be divided into the dysmorphic uterus (U1); septate uterus (U2); bicorporeal uterus (U3); hemi-uterus (U4) and hypoplastic uterus (U5) with clinical significance ranging from mild to severe. This study …

OBJECTIVE: To understand prevalence, severity, impact, and treatment of vasomotor symptoms associated with menopause, using cross-sectional survey data. METHODS: This online, two-part survey was conducted in East Asia among women 40-65 yea…

We aimed to investigate the relationship between testosterone (T) levels and pregnancy outcomes in patients with tubal or male infertility at different times during in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles…

Findings regarding the relationship between smooth endoplasmic reticulum clusters (SERCs) in oocytes and blastocyst development have been conflicting. In this study, the effects of SERCs on blastocyst quality and the speed of blastocyst dev…

STUDY OBJECTIVE: Endometriosis is the most common cause of secondary dysmenorrhea among adolescents. Data on postoperative symptoms of the disease in adolescents are limited. In this study we aimed to describe the clinical characteristics a…

Study objective: To generate and validate nomograms to predict any-stage and stage III-IV endometriosis before surgery in infertile women. Design: A single center retrospective cohort study. Setting: University affiliated hospital. Patients…

Hyperprolactinemia has long been considered detrimental to fertility due to irregularity of ovulation. Whether mild hyperprolactinemia should be corrected before initiating an in-vitro fertilization/intracytoplasmic sperm injection cycle (I…

PURPOSE: To investigate the potential etiologies of premature ovarian insufficiency (POI) and diminished ovarian reserve (DOR). METHODS: Fourteen women with sporadic POI and 6 women with DOR were enrolled. We used whole-exome sequencing (W…

Abstract Background: GnRH-agonist is used to treat adenomyosis, but its efficacy in adenomyosis patients with uterine enlargement undergoing frozen embryo transfer (FET) is unclear. Methods： The retrospective cohort study comprised 112 aden…

BACKGROUND: Dienogest provided significantly greater reduction in endometriosis-associated pelvic pain (EAPP) than placebo in a 24-week, randomized, double-blind study of Chinese women with endometriosis. The current open-label extension st…

AIM: As RNA, which plays a role in the regulation of endometrial receptivity, can be modulated via ceRNA mechanisms, we constructed a ceRNA network to explore potential RNA/ceRNA biomarkers indicating endometrial receptivity associated with…

Different sizes of uterine septum between infertile women and patients with abortions may have a clinical relevance in reproductive performance after surgery. This study aimed to assess if the fecundity of women after surgical correction of…

OBJECTIVE: Endometriosis is a common gynecologic disease that frequently leading to chronic pelvic pain, severe dysmenorrhea, and subfertility. As first-line hormonal treatment can interfere with ovulation and may cause recurrent pelvic pai…

Mammalian target of rapamycin (mTOR) is a conserved serine/threonine kinase of the phosphatidylinositol kinase-related kinase family that regulates cell growth, metabolism, and autophagy. Extensive research has linked mTOR to several human …

BACKGROUND: To investigate the efficacy and safety of a combined oral contraceptive containing estradiol valerate and dienogest (EV/DNG) in healthy Asian women. METHODS: In this multicenter Phase III study, women received oral EV/DNG in a …

BACKGROUND: To investigate the efficacy and safety of estradiol valerate (EV)/dienogest (DNG) for the management of heavy menstrual bleeding (HMB) in Asian and non-Asian women desiring contraception. MATERIALS AND METHODS: In this multicen…
