Peritoneal endometriosis causes pelvic pain and infertility, but the underlying mechanisms related to these symptoms are not fully understood. Endometriosis diagnosis is typically delayed; thus, patient samples are unsuitable to study early…

Abstract Peritoneal endometriosis causes pelvic pain and infertility, but the underlying mechanisms related to these symptoms are not fully understood. Endometriosis diagnosis is typically delayed; thus, patient samples are unsuitable to st…

STUDY QUESTION: What is the hormone receptor profile of adenomyosis lesions in comparison to correctly located endometrium? SUMMARY ANSWER: Adenomyosis lesions exhibit increased oestrogen receptor (ER) expression compared to the eutopic en…

Abstract Study question Can an in vitro patient-derived multicellular model of superficial endometriosis be generated to support studies exploring associated fibrosis? Summary answer The three-dimensional (3D) co-culture of primary peritone…

• Urine tests were the preferred option for the diagnosis of endometriosis • Tampon and stool tests were considered to be “uncomfortable” or “embarrassing” • All non-invasive tests were found to be acceptable if accurate for diagnosis Chron…

Abstract Endometriosis is a chronic, hormone-dependent condition that affects 190 million women worldwide. There are no validated biomarkers for endometriosis and this delays diagnosis and treatment. We performed serum steroid metabolome pr…

BACKGROUND/OBJECTIVE: Current guidelines recommend biopsychosocial-informed treatment for chronic pelvic pain (CPP). The objective of this systematic review was to describe the available biopsychosocial approaches for the treatment of CPP, …

Abstract: Chronic pelvic pain (CPP) is a debilitating condition that reduces quality of life (QoL). In the United Kingdom, there is currently no standardised treatment pathway for women suffering from CPP. Therefore, it is essential to unde…

STUDY QUESTION: Can a functional in vitro model, containing the main cellular components of the uterine wall, be generated from cells derived from patient tissues? SUMMARY ANSWER: We present a three-dimensional (3D) physiologically relevan…

Abstract Study question How does the transcriptome of adenomyosis lesions compare to the matched eutopic endometrium, and can they be targeted with lesion-specific treatments? Summary answer Adenomyosis lesions are transcriptionally distinc…

Abstract Introduction Endometriosis impacts 1 in 10 women and can be a debilitating disease. Late diagnosis is a major challenge with Endometriosis, contributing further to the exacerbation of symptoms and suboptimal clinical management. Re…

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…

STUDY QUESTION: What is the role of iron in the pathophysiology of endometriosis? SUMMARY ANSWER: Iron excess is demonstrated wherever endometriotic tissues are found and is associated with oxidative stress, an inflammatory micro-environmen…

BACKGROUND: Heavy menstrual bleeding affects one in four women and negatively impacts quality of life. Ulipristal acetate is prescribed to treat symptoms associated with uterine fibroids. We compared the effectiveness of ulipristal acetate …

Deep endometriosis (DE) is the most severe subtype of endometriosis, with the hallmark of lesions infiltrating adjacent tissue. Abnormal vascularisation has been implicated in contributing to endometriosis lesion development in general, and…

The human endometrium is one of the most regenerative tissues in the body, undergoing over 400 cycles of menstrual shedding and regeneration during reproductive life [...].

BACKGROUND: Human endometrium remains a poorly understood tissue of the female reproductive tract. The superficial endometrial functionalis, the site of embryo implantation, is repeatedly shed with menstruation, and the stem cell-rich deepe…

STUDY QUESTION: What are the effects of pre-analytical variables on the downstream analysis of patient-derived endometrial biopsies? SUMMARY ANSWER: ) in human endometrial biopsies, depending on the pre-analytical variables: disease status …

The fallopian tubes (FT) play a key role in fertility by facilitating the movement of gametes to promote fertilisation and, subsequently, passage of the zygote for implantation. Histologically, the FT mucosa consists of three main cell type…

Recurrent implantation failure (RIF) and recurrent pregnancy loss (RPL), collectively referred to as recurrent reproductive failure (RRF), are both challenging conditions with many unanswered questions relating to causes and management opti…

BACKGROUND: It is important to evaluate sequalae for complex chronic health conditions such as endometriosis and mental health disorders. Endometriosis impacts 1 in 10 women. Mental health outcomes can be a primary determinant in many physi…

BACKGROUND: Symptoms associated with menstruation and endometriosis are common amongst women of reproductive ages and the pathogenesis of these illnesses is postulated to be associated with aberrations in endometrial regeneration, immune re…

Abstract Study question Are women who report a previous surgical diagnosis of endometriosis more likely to have a diagnosis or symptoms suggestive of restless leg syndrome (RLS)? Summary answer: Women who reported a prior surgical diagnosis…
