BACKGROUND/AIMS: Dysregulated long non-coding RNAs (lncRNAs) can lead to the occurrence of various diseases; however, reports of the function of lncRNAs in endometriosis and related studies are scarce. The pathogenesis of endometriosis is s…

BACKGROUND: The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable compari…

BACKGROUND: We investigated possible biomarkers for endometriosis (EM) using the ClinProt technique and proteomics methods. METHODS: We enrolled 50 patients with EM, 34 with benign ovarian neoplasms and 40 healthy volunteers in this study.…

In this systematic review and meta-analysis, the effect of ovarian endometrioma on ovarian responsiveness to stimulation and on assisted reproduction outcomes was evaluated. Nine published studies (1039 cases) were included. The number of o…

PURPOSE: To probe the magnetic resonance imaging (MRI) features of ovarian clear cell carcinoma (OCCC). METHODS: This study retrospectively collected MRI data for 21 pathology-confirmed OCCCs from 19 female patients. The MRI findings were …

OBJECTIVES: This study is to investigate the role and mechanism of microRNA-202 (miR-202) in endometriosis. METHODS: Forty-five cases of ectopic endometrial tissues, 25 cases of eutopic endometrial tissues and 26 cases of normal endometria…

Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmen…

OBJECTIVE: This study measured the human epididymis protein 4 (HE4) and CA125 levels in Chinese women with benign gynecological disorders. MATERIAL AND METHODS: Sera were obtained from Chinese women prior to surgery for a pelvic mass and H…

To determine early somatic changes in high-grade serous ovarian cancer (HGSOC), we performed whole genome sequencing on a rare collection of 16 low stage HGSOCs. The majority showed extensive structural alterations (one had an ultramutated …

OBJECTIVE: Human epididymis protein 4 (HE4) is a promising biomarker of epithelial ovarian cancer (EOC). But its role in assessing the primary optimal debulking (OD) of EOC remains unknown. The purpose of this study is to elucidate the abil…

This study measured the antioxidant activity of follicular fluid (FF) in infertile patients and assessed its possible correlation between ovarian stimulation and pregnancy outcomes. Samples from 191 infertile patients undergoing in vitro fe…

The objective of this retrospective study was to analyze the clinical characteristics and prognosis of clear cell adenocarcinoma (CCA) in the post-diethylstilbestrol (DES) era and to evaluate the feasibility of fertility-preserving treatmen…

BACKGROUND: Recent studies have indicated the use of gonadotropin-releasing hormone antagonists (GnRH-ant) as an adjuvant treatment to prevent premature luteinization (PL) and improve the clinical outcomes in patients undergoing controlled …

BackgroundDehydroepiandrosterone (DHEA) is now widely used as an adjuvant to IVF treatment protocols in poor responders. However, clinical evidence for DHEA on improvement of ovarian response and IVF outcome is still limited, the validity o…

Two trials of clinically approved human papillomavirus (HPV) vaccines, Females United to Unilaterally Reduce Endo/Ectocervical Disease (FUTURE I/II) and the Papilloma Trial Against Cancer in Young Adults (PATRICIA), reported a 22% differenc…

OBJECTIVE: To evaluate the effects of lesion location on adhesion and angiogenesis of transplanted endometriotic lesions in SCID mice. METHODS: Three groups of female SCID mice included intraperitoneal (i.p.) (n = 12), subcutaneous (s.c.) …

OBJECTIVE: To investigate the effects of oxygen on the proliferation and angiogenesis of endometriosis in vivo. DESIGN: Animal studies. SETTING: Animal research facility. ANIMAL(S): Thirty-six female severe combined immunodeficiency (SCI…

During the last decades, many studies have shown the possible influence of sperm DNA fragmentation on assisted reproductive technique outcomes. However, little is known about the impact of sperm DNA fragmentation on the clinical outcome of …

OBJECTIVE: To investigate the expression of nerve growth factor (NGF) in the ectopic endometrium in adenomyosis patients, and explore the relationship between NGF expression and innervation or pain scales. METHODS: From Mar. 2009 to Oct. 2…

OBJECTIVE: To explore the association between the genetic variant of E-cadherin gene and endometriosis-related infertility. DESIGN: Case-control study. SETTING: University hospital. PATIENT(S): Five hundred eighty-nine women with ovarian…

Abnormal expression of nerve growth factor (NGF) was found in adenomyosis (AM). We collected AM foci from patients and eutopic endometrium from non-AM controls. Endometrium stromal cells (ESCs) were cultured. Different levels of 17β-estradi…

INTRODUCTION: Obstructing uterine septum is a rare uterine malformation. Patients with obstructing uterine septum are usually treated with laparouterotomy, causing obvious injury to both the uterus and body of the patients. Therefore, using…

BACKGROUND: Key roles for epigenetic mechanisms in tumorigenesis are well accepted, while the relationship between gene methylation and malignant transformation of ovarian endometriosis (EMS) was seldom reported. In this study, we aimed to …

This study aimed to induce malignant transformation of endometriosis in Sprague-Dawley rats by hyperestrogenemia and type II diabetes and evaluate its similarity with human disease in biological features. Rats with surgically induced endome…
