Uterine leiomyomas are the most common benign gynaecological tumours and a major cause of heavy menstrual bleeding, frequently resulting in iron deficiency anaemia. However, the long-term cardiovascular and thromboembolic consequences of fi…

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: Hydrosalpinx is a chronic pathological manifestation seen in approximately 30% of tubal disease cases. In addition to contributing to infertility and pelvic pain, hydrosalpinx has been associated with early pregnancy loss and redu…

Endometriosis is a chronic inflammatory condition affecting 10% of reproductive-age women. Current treatments remain limited and non-curative. While its biology is largely informed by human biospecimens, sample heterogeneity and methodologi…

Adenomyosis is a common gynecological condition characterized by ectopic endometrial-like tissue deep within the myometrium, causing debilitating symptoms. Treatment options are limited to hormones that primarily focus on symptom management…

OBJECTIVE: Endometriosis is a chronic, hormone-dependent condition affecting an estimated 190 million women worldwide. Our understanding of hormonal contributions to endometriosis pathophysiology is incomplete, hindering the identification …

Recurrent implantation failure (RIF) is a devastating condition that leaves many undergoing fertility treatment childless. The human endometrium is receptive to a blastocyst for a brief period, the window of implantation. Critical knowledge…

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…

Stage-specific embryonic antigen-1 (SSEA-1)+ endometrial epithelial cells (EECs) assume the postulated stem/progenitor cell niche within the human endometrium. Previous studies have demonstrated that isolated SSEA-1+ cells have a higher cap…

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 questionDoes endometrial compaction (EC) help predict pregnancy outcomes in those undergoing ART?Summary answerEC is associated with a significantly higher clinical pregnancy rate (CPR) and ongoing pregnancy rate (OPR), but this does …

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…

Rates of infertility are rising, and informed decision making is an essential part of reproductive life planning with the knowledge that ART success decreases dramatically while a woman's age increases and that high costs can often be incur…

Inflammation is implicated in the symptomatology and the pathogenesis of adenomyosis. Injury at the endo-myometrial interface causes inflammation and may facilitate the invasion of endometrium into the myometrium, forming adenomyosis lesion…

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…

BACKGROUND: This systematic review aims to explore the prevalence of the impact of the COVID-19, MERS, and SARS pandemics on the mental health of pregnant women. METHODS: All COVID-19, SARS and MERS studies that evaluated the mental health…

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-environme…
