Genome-wide association studies (GWASs) may help inform the etiology of infertility. Here, we perform GWAS meta-analyses across seven cohorts in up to 42,629 cases and 740,619 controls and identify 25 genetic risk loci for male and female i…

STUDY QUESTION: Do the diagnostic delay and symptoms differ between endometriosis patients with advanced disease, defined as endometriosis involving the vagina, intestine, rectovaginal septum, or bladder (eVIRB), compared to patients withou…

Endometriosis is a common chronic gynecological disorder with complex and poorly understood etiology and no definitive cure. Beyond pain and infertility, affected individuals frequently experience psychiatric comorbidities, often attributed…

BACKGROUND: Endometriosis is a complex condition with a wide range of comorbidities. It is widely underdiagnosed, with a diagnostic delay of 4 to 10 years, potentially leading to worsened disease progression and a higher burden of comorbidi…

Genome-wide association studies (GWASs) may help inform treatments for infertility, whose causes remain unknown in many cases. Here we present GWAS meta-analyses across six cohorts for male and female infertility in up to 41,200 cases and 6…

Endometriosis affects approximately 190 million women globally. Many individuals with endometriosis face complex journeys through the healthcare system, set against a backdrop of historically underfunded research into women’s health. This s…

OBJECTIVES: This study aims to translate and cross-culturally adapt the standard version of the World Endometriosis Research Foundation (WERF) EPHect Endometriosis Patient Questionnaire (EPQ) into Danish and to ensure equivalence of a Danis…

OBJECTIVE: To study whether endometriosis is associated with pregnancy loss and recurrent pregnancy loss (RPL). DESIGN: Nationwide historical cohort study with a nested case-control analysis. SETTING: National health registers. PATIENT(S…

Endometriosis is a common condition associated with debilitating pelvic pain and infertility. A genome-wide association study meta-analysis, including 60,674 cases and 701,926 controls of European and East Asian descent, identified 42 genom…

INTRODUCTION: Due to diagnostic challenges, normalization of symptoms and an overall lack of awareness among both patients and physicians, endometriosis is an underdiagnosed disease. This can result in delayed treatment and potentially wors…

STUDY QUESTION: Is there a shared genetic or causal association of endometriosis with asthma or what biological mechanisms may underlie their potential relationships? SUMMARY ANSWER: Our results confirm a significant but non-causal associat…

Endometriosis is a major health care challenge because many young women with endometriosis go undetected for an extended period, which may lead to pain sensitization. Clinical tools to better identify candidates for laparoscopy-guided diagn…

STUDY QUESTION: Do seminal plasma (SP) and its constituents affect the decidualization capacity and transcriptome of human primary endometrial stromal fibroblasts (eSFs)? SUMMARY ANSWER: SP promotes decidualization of eSFs from women with …

Observational epidemiological studies indicate that endometriosis and migraine co-occur within individuals more than expected by chance. However, the aetiology and biological mechanisms underlying their comorbidity remain unknown. Here we e…

Abstract Endometriosis is a common complex inflammatory condition characterised by the presence of endometrium-like tissue outside the uterus, mainly in the pelvic area. It is associated with chronic pelvic pain and infertility, and its pat…

Genome-wide association (GWA) studies have identified 19 independent common risk loci for endometriosis. Most of the GWA variants are non-coding and the genes responsible for the association signals have not been identified. Herein, we aime…

Endometriosis is a heritable hormone-dependent gynecological disorder, associated with severe pelvic pain and reduced fertility; however, its molecular mechanisms remain largely unknown. Here we perform a meta-analysis of 11 genome-wide ass…

OBJECTIVE: To harmonize standard operating procedures (SOPs) and standardize the recording of associated data for collection, processing, and storage of human tissues relevant to endometriosis. DESIGN: An international collaboration involvi…

OBJECTIVE: To harmonize the collection of nonsurgical clinical and epidemiologic data relevant to endometriosis research, allowing large-scale collaboration. DESIGN: An international collaboration involving 34 clinical/academic centers and …

OBJECTIVE: To harmonize standard operating procedures (SOPs) and standardize the recording of associated data for collection, processing, and storage of fluid biospecimens relevant to endometriosis. DESIGN: An international collaboration in…

The identification of molecular differences in the endometrium of women with endometriosis is an important step toward understanding the pathogenesis of this condition and toward developing novel strategies for the treatment of associated i…
