Chronic pelvic pain (CPP) affects ∼15% of women and gender-diverse people, yet it is often dismissed by health care providers, partly due to a lack of related medical education. This brief communication describes the findings of a needs ass…

There is increasing recognition that nociplastic pain and central sensitization may play a role in endometriosis-associated pain. The Pain Sensitivity Questionnaire Minor (PSQ-M) evaluates subjective widespread pain sensitivity, and is link…

OBJECTIVES: To evaluate whether endometriosis and menstrual health education improves knowledge and attitudes among adolescents and is acceptable. METHODS: We conducted a cluster-randomised controlled trial in a Canadian school district. E…

BACKGROUND: Deep dyspareunia affects 50% of people with endometriosis. The Ohnut is a set of interlocking rings that fit over the penis/insertive object. One or more rings can be used to limit insertion depth and reduce deep dyspareunia. A…

BACKGROUND: Pelvic pain worsened by orgasm is a poorly understood symptom in patients with endometriosis. AIM: To assess the prevalence of pelvic pain worsened by orgasm in patients with endometriosis and explore its association with poten…

STUDY QUESTION: Is there an association between the somatic loss of PTEN (phosphatase and tensin homolog) and ARID1A (AT-rich interaction domain 1A) and endometriosis disease severity and worse clinical outcomes? SUMMARY ANSWER: Somatic PT…

BACKGROUND: Approximately half of people with endometriosis experience deep dyspareunia; however, there is no means of objective self-testing of endometriosis-associated deep dyspareunia. AIM: The aim of this study was to assess the accept…

IMPORTANCE: A subset of people who undergo surgery for endometriosis have persistent pain, suggesting that other factors besides the endometriosis, such as central sensitization, may play a role in this pain. The Central Sensitization Inven…

Endometriosis is a common condition in women that causes chronic pain and infertility and is associated with an elevated risk of ovarian cancer. We profiled transcriptomes of >370,000 individual cells from endometriomas (n = 8), endometrios…

INTRODUCTION: We propose a standardized protocol for measurement of nerve bundle density in endometriosis as a potential biomarker, including in deep endometriosis (DE), ovarian endometriomas (OMA) and superficial peritoneal endometriosis (…

Abstract Endometriosis is a common, benign condition characterized by extensive heterogeneity in lesion appearance and patient symptoms. We profiled transcriptomes of 207,949 individual cells from endometriomata (n=7), extra-ovarian endomet…

A key clinical problem is identifying the patient with endometriosis whose pain is complicated by central nervous system sensitization, where conventional gynecologic treatment (eg, hormonal therapy or surgery) may not completely alleviate …

Background: Endometriosis is a complex condition that can negatively affect a woman's quality of life, including her sleep. This study aims to assess the multifactorial variables associated with poorer quality of sleep in women with endomet…

INTRODUCTION: Deep dyspareunia is a cardinal symptom of endometriosis, and as many as 40% of people with this condition experience comorbid superficial dyspareunia. AIM: To evaluate the relationship between sexual pain and infertility conc…

INTRODUCTION: Deep dyspareunia, a common symptom in endometriosis, has previously been associated with bladder and/or pelvic floor tenderness (BPFT), which suggests a role for central nervous system sensitization. The Central Sensitization …

OBJECTIVE: This study sought to identify factors independently associated with a negative impression of the medical profession in patients with endometriosis who were presenting to a tertiary referral centre. METHODS: A cross-sectional ana…

PURPOSE: Deep infiltrating endometriosis (DIE) is defined as an endometriotic lesion penetrating to a depth of >5 mm and is associated with pelvic pain, but the underlying mechanisms are unclear. Our objective is to investigate whether plas…

INTRODUCTION: The etiology of endometriosis-associated deep dyspareunia may include direct endometriosis-specific factors (eg, stage or invasiveness of disease) and/or indirect contributors such as bladder/pelvic floor dysfunction (eg, rela…

STUDY QUESTION: Does incisional endometriosis (IE) harbor somatic cancer-driver mutations? SUMMARY ANSWER: We found that approximately one-quarter of IE cases harbor somatic-cancer mutations, which commonly affect components of the MAPK/RA…
