  Abstract Introduction Pelvic and genital pain is a common symptom among women with endometriosis and may negatively affect sexual functioning. Pelvic floor muscle training (PFMT) may improve sexual functioning, but whether this applies to women with endometriosis remains to be explored. This study is a planned secondary analysis in which we aimed to examine how general exercise and PFMT, when added to pain management, affect sexual functioning among women with endometriosis. Material and Methods Planned secondary analysis of a two‐armed, parallel‐group randomized controlled trial with intention‐to‐treat analysis. Women aged 18–45 years with laparoscopically confirmed endometriosis and experiencing pelvic/genital pain were eligible. All participants attended a pain management course. In addition to weekly home training, the exercise group ( n  = 41) participated in weekly supervised general exercise training, including PFMT, for 4 months. The control group ( n  = 40) received no further intervention. Between‐group differences in sexual function were assessed using the total score of the Female Sexual Function Index (FSFI) at the end of the 4‐month intervention and at the 12‐month follow‐up. We also examined differences in the subdomains—desire, arousal, lubrication, orgasm, satisfaction, and pain—at these time points. Clinical Trial registration: NCT05091268. Results Four months post‐intervention, the exercise group showed significantly higher total FSFI scores compared to the control group (mean difference = 3.52, 95% CI 0.49–6.54, p  = 0.023). Significant between‐group differences were also observed for the subdomains lubrication (mean difference = 0.90, 95% CI 0.17–1.63, p  = 0.016) and orgasm (mean difference = 0.81, 95% CI 0.07–1.55, p  = 0.033). No significant between‐group differences were found for desire, arousal, or pain at the end of the 4‐month intervention, or at 12 months follow‐up for any domain. Conclusions The findings suggest that the combined intervention of supervised exercise and PFMT, when added to pain management, may lead to short‐term improvements in sexual function at the end of the 4‐month intervention. Whether this effect is attributable to general exercise, PFMT, or their combination cannot be determined from the present study. However, the findings should be interpreted cautiously due to differences in sexual activity status between groups.

  ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital, London, UK, between January 2017 and February 2024. Cytogenetic testing was offered routinely to patients experiencing recurrent miscarriage (at least two miscarriages) or was made available through self‐funding. Eligible participants had a singleton, normally sited pregnancy with evidence of cardiac activity on at least one ultrasound scan, and were subsequently diagnosed with a first‐trimester miscarriage, with successful cytogenetic testing of pregnancy tissue. Crude ultrasound measurements of gestational sac mean diameter (GSMD), yolk sac mean diameter (YSMD), crown–rump length (CRL) and embryonic heart rate from the last live ultrasound scan were converted to centiles according to established biometric reference data. Univariable and multivariable logistic regression analysis was used to assess associations between sonographic features and karyotype result. Results Among 158 cases included in the final analysis, 46 (29.1%) had a normal karyotype and 112 (70.9%) had an abnormal karyotype. Those with an abnormal karyotype had a significantly higher median maternal age at conception (38 (interquartile range (IQR), 34–41) years vs 35 (IQR, 33–38) years; P  = 0.0005). Median GSMD centile ( P  = 0.005) and median CRL centile ( P  = 0.003) were lower in pregnancies with an abnormal karyotype, while bradycardia (heart rate < 5 th  centile) ( P  = 0.04) and enlarged YSMD (≥ 95 th  centile) ( P  = 0.03) were more common in this group. A combination of four abnormal morphological features (GSMD < 5 th  centile + YSMD ≥ 95 th  centile + CRL < 5 th  centile + bradycardia), termed the ‘tetrad of aneuploidy’, predicted an abnormal karyotype (odds ratio, 7.51 (95% CI, 2.41–140.22); P  < 0.001), with a specificity of 100% (95% CI, 92.29–100%), for cases last examined sonographically ≤ 10 weeks' gestation. Conclusions The presence of a specific combination of abnormal early‐pregnancy ultrasound markers, termed the tetrad of aneuploidy, is a strong predictor of chromosomal abnormality in pregnancies presenting initially with a live embryo. Recognition of this pattern could improve patient counseling and inform clinical decision‐making in early pregnancy. © 2026 The Author(s).

  ABSTRACT Objective To assess whether premenopausal women diagnosed with deep or ovarian endometriosis on transvaginal sonography (TVS) were more likely to suffer from dyspareunia and pelvic pain symptoms, and have a lower quality of life, compared to women without sonographically diagnosed deep or ovarian endometriosis. Methods This was a prospective, cross‐sectional study carried out between February 2019 and October 2020 at the general gynecology clinic at University College London Hospital, London, UK. All premenopausal women aged 18–50 years, who were examined consecutively by a single experienced examiner and underwent a detailed TVS scan, were eligible for inclusion. Pregnant women and those who had received a previous diagnosis of endometriosis or who had experienced a hysterectomy or unilateral/bilateral oophorectomy were excluded. Sonographic findings consistent with deep or ovarian endometriosis were noted. All women completed the British Society of Gynaecological Endoscopy pelvic pain questionnaire. The primary outcome was to determine whether women with sonographic evidence of endometriosis were more likely to experience moderate‐to‐severe levels of dyspareunia (score of ≥ 4 on an 11‐point numerical rating scale (NRS)). Secondary outcomes included assessing moderate‐to‐severe levels of other pelvic pain symptoms (NRS score of ≥ 4), bowel symptoms (score of ≥ 2 on a 5‐point Likert scale) and quality of life, which was measured using the EuroQol‐5D‐3L (EQ‐5D) questionnaire. The number of women with pain scores ≥ 4 and bowel scores ≥ 2, as well as the mean EQ‐5D scores, were compared between the group with and that without sonographic evidence of endometriosis using logistic regression analysis, and multivariable analysis was used to adjust for demographic and clinical variables. Results A total of 514 women were included in the final study population, of whom 146 (28.4%) were diagnosed with deep or ovarian endometriosis on TVS. On multivariable analysis, the presence of moderate‐to‐severe dyspareunia was not found to be associated with endometriosis. Moderate‐to‐severe dyspareunia was significantly associated with lower age (odds ratio (OR), 0.70 (95% CI, 0.56–0.89); P  = 0.003) and a history of migraine (OR, 3.52 (95% CI, 1.42–8.77); P  = 0.007), and it occurred significantly less frequently in women with non‐endometriotic ovarian cysts (OR, 0.47 (95% CI, 0.28–0.78); P  = 0.003). There was also a trend towards a positive association between anxiety/depression and moderate‐to‐severe dyspareunia (OR, 1.94 (95% CI, 0.93–4.03); P  = 0.08). Following multivariable analysis, the only symptoms that were significantly more common in women with endometriosis compared to those without were menstrual dyschezia (OR, 2.44 (95% CI, 1.59–3.78); P  < 0.001) and difficulty emptying the bladder (OR, 2.56 (95% CI, 1.52–4.31); P  < 0.001). Although not reaching statistical significance on multivariable analysis, dysmenorrhea (OR, 1.72 (95% CI, 0.92–3.20); P  = 0.09) and lower EQ‐5D score (mean ± SD, 0.67 ± 0.33 vs 0.72 ± 0.28; P  = 0.06) also occurred more frequently in women with sonographic evidence of endometriosis. Conclusions The majority of pelvic pain symptoms did not differ significantly between women with and those without sonographic evidence of endometriosis, indicating that endometriosis may not always be the source of pelvic pain, even if present. This highlights the need to rule out other causes of pain in symptomatic endometriosis patients before considering surgical procedures, and to provide appropriate patient counseling. © 2024 The Author(s).

  Question: How much does adding supervised group and independent individual exercise including pelvic floor muscle training (PFMT) to multidisciplinary pain management affect pelvic and genital pain in women with endometriosis? How much does it affect dyspareunia, dysuria, quality of life (with emphasis on psychological distress, including symptoms of depression and anxiety), symptoms of chronic constipation and pelvic floor muscle (PFM) function? Design: A two-armed, parallel-group, randomised controlled trial with concealed allocation, intention-to-treat analysis and blinded assessment of some outcomes. Participants: Women aged 18 to 45 years with laparoscopically confirmed endometriosis experiencing pelvic/genital pain. Intervention: All participants attended a pain management course. The exercise group (n = 41) then performed weekly supervised general exercise training including PFMT for 4 months, and home training two to three times/week. The control group (n = 40) received no further intervention. Outcome measures: Primary outcomes were the change in worst pelvic/genital pain over 1 month and current pelvic/genital pain measured on a numerical rating scale at 4 and 12 months. Secondary outcomes measured at the same time points were: location and concerns related to dyspareunia; presence of dysuria; symptoms of chronic constipation assessed with the Knowles-Eccersley-Scott-Symptom scale; and quality of life with emphasis on psychological distress, including symptoms of depression and anxiety assessed with Hopkins Symptom Checklist-5. PFM function was measured with surface electromyography and manometry at baseline and 4 months. Results: The intervention did not improve worst pelvic/genital pain but it did have a clear benefit on current pelvic/genital pain at the end of the intervention (MD 1.1, 95% CI 0.2 to 2.1). This benefit was still present at the 12-month follow-up (MD 1.5, 95% CI 0.2 to 2.7). The effects on other outcome measures were unclear. Conclusion: Adding supervised group and independent individual exercise including PFMT to pain management did not improve worst pelvic/genital pain but improved current pelvic/genital pain. Effects on other outcomes warrant further investigation.

  Background Endometriosis and adenomyosis are common benign conditions compromising both physical and psychological health, with a negative impact on quality of life. This survey aimed to establish what the users’ perspectives are on best possible care in the context of developing a multidisciplinary center for endometriosis and adenomyosis in Norway. Methods An electronic questionnaire was developed in collaboration between the Norwegian Patient’s Endometriosis Society (NPES) and gynecologists with special interest in endometriosis and adenomyosis. The questionnaire was distributed digitally to the members of NPES in May 2021. Results 938 participants answered the questionnaire. Better patient information, long term therapeutic plans and integration of their partners into their care were the main concerns. Multidisciplinary care was a key issue for the majority, with (n = 775) 89% stating a need for a consultation with a psychologist, (n = 744) 86% at least one consultation with a nutritionist, (n = 733) 85% a physiotherapist, and (n = 676) 78% needing a sex therapist and (n = 935) 99,7% consider research and (n = 934) 99,8% consider quality assurance initiated by the endometriosis center to be important. The qualitative analysis of free text answers revealed a great need for updated and easily accessible information, meeting competent health care professionals and being taken seriously/listened to. Conclusions This survey shows similar perceptions and a high level of agreement regarding their needs amongst people with endometriosis and/or adenomyosis. This survey supports recommendations by the experts that endometriosis/adenomyosis care should be centralized in specialized, multidisciplinary centers. The results of the present work will be valuable for the future planning and development of a multidisciplinary endometriosis center.

  Abstract Cyclic and noncyclic chronic pelvic pain (CPP) represent a major problem for both affected patients and healthcare providers due to its effects on physical and mental health. In times of social media and digitalization, awareness of endometriosis as a leading cause of CPP is increasing. However, a close look at the current literature does not support endometriosis as the predominant and most common cause of pelvic pain syndromes and associated morbidities. Consequently, other or additional factors may be overlooked, complex pain mechanisms simplified, and symptoms misunderstood, resulting in less optimal treatment concepts. This commentary underlines the necessity to evaluate patients with CPP and suspected endometriosis in a multifactorial and holistic context to provide a better framework of patient care.

  Study question: What recommendations can be provided to improve terminology for normal and ectopic pregnancy description on ultrasound? Summary answer: The present ESHRE document provides 17 consensus recommendations on how to describe normally sited and different types of ectopic pregnancies on ultrasound. What is known already: Current diagnostic criteria stipulate that each type of ectopic pregnancy can be defined by clear anatomical landmarks which facilitates reaching a correct diagnosis. However, a clear definition of normally sited pregnancies and a comprehensive classification of ectopic pregnancies are still lacking. Study design size duration: A working group of members of the ESHRE Special Interest Group in Implantation and Early Pregnancy (SIG-IEP) and selected experts in ultrasound was formed in order to write recommendations on the classification of ectopic pregnancies. Participants/materials setting methods: The working group included nine members of different nationalities with internationally recognised experience in ultrasound and diagnosis of ectopic pregnancies on ultrasound. This document is developed according to the manual for development of ESHRE recommendations for good practice. The recommendations were discussed until consensus by the working group, supported by a survey among the members of the ESHRE SIG-IEP. Main results and the role of chance: A clear definition of normally sited pregnancy on ultrasound scan is important to avoid misdiagnosis of uterine ectopic pregnancies. A comprehensive classification of ectopic pregnancy must include definitions and descriptions of each type of ectopic pregnancy. Only a classification which provides descriptions and diagnostic criteria for all possible locations of ectopic pregnancy would be fit for use in routine clinical practice. The working group formulated 17 recommendations on the diagnosis of the different types of ectopic pregnancies on ultrasound. In addition, for each of the types of ectopic pregnancy, a schematic representation and examples on 2D and 3D ultrasound are provided. Limitations reasons for caution: Owing to the limited evidence available, recommendations are mostly based on clinical and technical expertise. Wider implications of the findings: This document is expected to have a significant impact on clinical practice in ultrasound for early pregnancy. The development of this terminology will help to reduce the risk of misdiagnosis and inappropriate treatment. Study funding/competing interests: The meetings of the working group were funded by ESHRE. T.T. declares speakers' fees from GE Healthcare. The other authors declare that they have no conflict of interest.
