Abstract
Introduction
Dyspareunia has been called the neglected symptom of endometriosis and is underexplored in clinical and research contexts. Understanding the physical experience and patient-important aspects of endometriosis-associated sexual pain can help advance valid measurement of this symptom.
Aims
The goal of this research was to characterize the physical experience of endometriosis-associated dyspareunia in the words of people affected by this condition.
Methods
This was a qualitative descriptive study that included participants with current or previous endometriosis-associated dyspareunia recruited from a data registry. Data collection involved semistructured interviews that began with an open-ended question about dyspareunia followed by prompts related to the nature of sexual pain.
Main Outcome Measures
Interviews transcripts were subjected to qualitative content analysis using a priori (pain site, onset, character, radiation, associations, time course, and exacerbating/relieving factors) and emergent themes.
Results
A total of 17 participants completed interviews. Mean participant age was 33.3 years and most were identified as white, college-educated, heterosexual, and partnered. Location, onset, and character were important; interrelated features of endometriosis-associated dyspareunia were: (i) introital pain began with initial penetration and had pulling, burning, and stinging qualities and (ii) pelvic pain was experienced with deep penetration or in certain positions and was described as sharp, stabbing, and cramping. Dyspareunia ranged from mild to severe, had a marked psychosocial impact for some participants, and was managed using a variety of treatments and strategies.
Conclusion
The endometriosis-associated dyspareunia experienced by participants was heterogenous in presentation, severity, and impact. Our findings have implications for the development of valid patient-reported outcome measures of this symptom. Wahl KJ, Imtiaz S, Lisonek M, et al.

Impact of the coronavirus disease-2019 (COVID-19) pandemic on reproductive outcomes in patients with recurrent pregnancy loss
Balachandran S et al., 2026 · Journal of obstetrics and gynaecology Canada : JOGC = Journal d'obstetrique et gynecologie du Canada : JOGC
To assess the impact of the COVID-19 pandemic on reproductive outcomes in patients with recurrent pregnancy loss (RPL) and the influence of material and social deprivation on these outcomes. This retrospective cohort study included RPL patients seen at a specialized clinic between March 1, 2018, and February 28, 2022. Patients were categorized into two groups based on care period: pre-pandemic (March 1, 2018-February 29, 2020) and pandemic (March 1, 2020-February 28, 2022). Cumulative probabilities of birth were estimated using the cumulative incidence function within a competing risk framework, treating pregnancy loss as a competing event. Fine and Gray regression models calculated sub-distribution hazard ratio (sHR) of birth. 544 patients were included in the study, with 255 in the pre-pandemic group and 289 in the pandemic group. Individuals in the pandemic group were less likely to achieve pregnancy than those in the pre-pandemic group (relative risk = 0.50, 95% confidence interval [CI] 0.39 - 0.66). Among those who conceived, the cumulative probability of live birth was 0.77 in both groups. Relative to individuals residing in high-social deprivation neighborhoods, those living in moderately deprived areas had higher sub-distribution hazards of live birth (adjusted sHR = 1.97, 95% CI 1.25 - 3.10; P = 0.003). Within specialized RPL care and a universal maternity care system, pregnancy rates were lower during the first two years of the COVID-19 pandemic. However, among those who conceived, the probability of achieving a live birth remained similar between the pre-pandemic and pandemic periods.

Endometriosis, symptoms, and risk for depression and/or anxiety: a population-based retrospective study
Goodwin E et al., 2025 · BMC women's health · Free full text on PubMed Central
Endometriosis is a chronic and inflammatory condition that often presents with chronic pelvic pain, dysmenorrhea, and dyspareunia, thus having important effects on quality of life. There are two proposed hypotheses to describe the known association between endometriosis and depression and anxiety: (1) the disease hypothesis, where the inflammatory nature of endometriosis is driving increased risk for depression and anxiety; and (2) the pain hypothesis, where it is the painful symptoms underlying the increased risk. We aimed to shed further light on these two hypotheses by assessing the risk for depression and/or anxiety in three groups of patients pathologically assessed for endometriosis: symptomatic endometriosis patients (Symp Endo), symptomatic patients with no pathological endometriosis diagnosis (Symp No Endo), and asymptomatic endometriosis patients (Asymp Endo). This study included pathologically-confirmed endometriosis patients identified from the pathology records of Vancouver Coastal Health Authority between 2000 and 2008. These data were linked with population-based administrative health data for follow-up to 2017. Depression and anxiety were identified through diagnostics codes from health services use data and prescriptions for antidepressants. Bivariate analyses were performed to assess differences between groups. Cox proportional hazards models were run to generate hazard ratios for incident depression and/or anxiety between the groups. There were 2729 people in Symp Endo, 585 in Symp No Endo, and 326 in Asymp Endo. Symp No Endo was more likely than Symp Endo to be visiting a physician for pelvic pain and to be taking prescription-level pain medications (p < 0.001). After adjusting for several covariates, Symp No Endo had a significantly higher risk of incident depression and/or anxiety (adjusted HR: 1.23, 95% CI: 1.06-1.41) compared to Symp Endo. There was no statistically significant difference in risk of depression and/or anxiety between Symp Endo and Asymp Endo (adjusted HR: 0.94, 95% CI: 0.76-1.17). These results point toward the pain focused hypotheses as Symp No Endo patients were at higher risk for depression/anxiety than the Symp Endo group. However, the results also suggest the disease hypothesis is at play, because the Symp Endo and Asymp Endo groups were at the same level of risk for depression/anxiety.

Female Dyspareunia and the Relationship to Neurophysiologic Mechanisms: A Scoping Review
Cook E et al., 2026 · Journal of minimally invasive gynecology
This scoping review aims to evaluate recent studies that examine the relationship between dyspareunia and neurophysiologic factors, and to synthesize their results as it pertains to the development and treatment of introital/vulvar dyspareunia and deep dyspareunia A comprehensive search was conducted in PubMed (NLM), Embase (Elsevier), CINAHL (EBSCOhost), Web of Science (Clarivate), Psycinfo (ProQuest), and Cochrane Library (Wiley) to find peer reviewed studies written in English published in 2000 or later that discussed how neurophysiology is related to dyspareunia. Search terms: dyspareunia; painful intercourse; genito-pelvic pain; penetration disorder; neuropsychology; central nervous system sensitization; neur; central sensitization. A total of 1101 studies were screened and 108 were included in the review. Abstract and full text screening were performed by 4 authors. Articles were also excluded if they did not include an objective diagnostic tool or objective treatment outcome of dyspareunia. We included original peer-reviewed published research in the form of randomized control trials, cohort studies, case control studies, case series of greater than 20 participants, and systematic reviews. Multiple study types were noted: 22 randomized control trials, 9 prospective cohort studies, 3 retrospective cohort studies, 30 case control, 16 case series, 17 cross-sectional, and 11 systematic reviews. Of these articles, 72 focused on introital/superficial dyspareunia, 23 focused on deep dyspareunia, and 13 on both. Data was synthesized in text and table format, separated by type of dyspareunia (introital vs deep) and either etiology/diagnosis or treatment. There are complex neurophysiologic mechanisms that influence both introital and deep dyspareunia, highlighting the roles of peripheral and central sensitization, nerve fiber density, and neuroplasticity in this condition. There are several promising treatments, including TENS, botulinum toxin A, physical therapy, and various multimodal approaches; but further research is needed to establish standardized therapeutic guidelines.

Impact of the COVID-19 pandemic on pregnancy complications and conceptions resulting in births following spontaneous conception and in-vitro fertilization in British Columbia: A population-based study
Eckler R et al., 2025 · PloS one · Free full text on PubMed Central
To investigate the impact of the COVID-19 pandemic's onset on clinical and demographic characteristics, pregnancy complications, and monthly conception rates resulting in births through spontaneous conceptions and in-vitro fertilization (IVF) in British Columbia (BC), Canada. This retrospective population-based cohort study examined individuals who gave birth (both live births and stillbirths) in BC between June 1, 2010, and March 31, 2021, with estimated conception dates from January 1, 2010 to June 30, 2020. Data were obtained from the BC Perinatal Data Registry. Two groups were identified based on the estimated conception date: the pre-pandemic conception group (conception from January-1-2010 to February-29-2020) and the pandemic conception group (conception from March-1-2020 to June-30-2020). A time series forecasting method (ARIMA) was employed to observe trends in conception rates during the study period. 304,244 individuals with pregnancies resulting in live births or stillbirths during the study period were evaluated. A total of 429,843 such conceptions were included in the study: 417,753 (97.2%) occurring before the onset of the pandemic and 12,090 (2.8%) in the pandemic period. In June 2020, conceptions resulting in births decreased by 26.6% compared with June 2019. Trends in conceptions resulting in live births were similar, with a conception rate of 235.2 per 100,000 women of reproductive age in June 2020, compared with the expected rate of 305.0 per 100,000. In March 2020, 0.5% of conceptions that resulted in births ended in stillbirths, compared to 1.7% in March 2019. IVF conceptions ending in births declined during the pandemic, dropping to 2.5 and 2.8 per 100,000 in March and April 2020, respectively, compared with the expected 13.1 per 100,000. However, by June 2020, these rates began to recover toward the expected levels. Rates of gestational diabetes mellites (GDM), gestational hypertension (GHTN), and postpartum intensive care unit (ICU) admissions were similar before and during the COVID-19 pandemic. During the challenging period of the COVID-19 pandemic in BC, couples may have chosen to delay conception. Rates of conceptions resulting in stillbirths remained relatively unchanged. IVF conception rates were impacted by the suspension of elective procedures. Preterm birth rates slightly exceeded expected levels but remained within normal fluctuations, and small increases in GDM and GHTN prevalence were also observed.

Deep Dyspareunia in Endometriosis: A Proposed Framework Based on Pain Mechanisms and Genito-Pelvic Pain Penetration Disorder
Yong PJ, 2017 · Sexual medicine reviews
Endometriosis is a common chronic disease affecting 1 in 10 women of reproductive age, with half of women with endometriosis experiencing deep dyspareunia. A review of research studies on endometriosis indicates a need for a validated question or questionnaire for deep dyspareunia. Moreover, placebo-controlled randomized trials have yet to demonstrate a clear benefit for traditional treatments of endometriosis for the outcome of deep dyspareunia. The reason some patients might not respond to traditional treatments is the multifactorial nature of deep dyspareunia in endometriosis, which can include comorbid conditions (eg, interstitial cystitis and bladder pain syndrome) and central sensitization underlying genito-pelvic pain penetration disorder. In general, there is a lack of a framework that integrates these multifactorial causes to provide a standardized approach to deep dyspareunia in endometriosis. To propose a clinical framework for deep dyspareunia based on a synthesis of pain mechanisms with genito-pelvic pain penetration disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Narrative review after literature search with the terms (endometriosis AND dyspareunia) OR (dyspareunia AND deep) and after analysis of placebo-controlled randomized trials. Deep dyspareunia presence or absence or deep dyspareunia severity on a numeric rating scale or visual analog scale. Four types of deep dyspareunia are proposed in women with endometriosis: type I that is directly due to endometriosis; type II that is related to a comorbid condition; type III in which genito-pelvic pain penetration disorder is primary; and type IV that is secondary to a combination of types I to III. Four types of deep dyspareunia in endometriosis are proposed, which can be used as a framework in research studies and in clinical practice. Research trials could phenotype or stratify patients by each type. The framework also could give rise to more personalized care for patients by targeting appropriate treatments to each deep dyspareunia type. Yong PJ.

Deep Dyspareunia and Sexual Quality of Life in Women With Endometriosis
Shum LK et al., 2018 · Sexual medicine · Free full text on PubMed Central
Deep dyspareunia occurs in half of women with endometriosis, a condition present in 10% of reproductive-age women and associated with negative effects on sexual quality of life (SQoL). However, women with endometriosis can have other clinical factors (eg, superficial dyspareunia, other pelvic pains, and psychological or pain conditions) possibly affecting SQoL. To determine whether deep dyspareunia is associated with SQoL in women with endometriosis, independent of potential confounders. This study involved a prospective patient registry of women at a tertiary-level referral center for endometriosis and pelvic pain. Inclusion criteria were (i) referrals to the center recruited into the registry from January 2014 through December 2016 and (ii) subsequent surgery at the center with histologic confirmation of endometriosis. Exclusion criteria included menopausal status, age at least 50 years, never sexually active, or did not answer dyspareunia or SQoL questions. Bi-variable tests and multiple linear regression analysis were performed. SQoL measured by the 5-item sexual intercourse subscale of the Endometriosis Health Profile-30 (EHP-30) modular questionnaire (0-100%, with higher scores indicating worse SQoL). Consent rate for the prospective registry was 87%; 277 women met the study criteria (mean age = 34.2 ± 7.1 years). Most women had stage I to II endometriosis at time of surgery (64%), with the remaining having stage III to IV endometriosis. Through regression analysis, worse SQoL (higher EHP-30 sexual intercourse subscale score) was independently associated with: more severe deep dyspareunia (P < .0001), more severe superficial dyspareunia (P < .0001), increased depression (P < .001), higher pain catastrophizing (P = .04), bladder pain syndrome (P = .02), heterosexual orientation (P < .001), and new referral status (P = .02). In women with endometriosis at a tertiary referral center, more severe deep dyspareunia was associated with worse SQoL, independent of superficial dyspareunia, psychological comorbidities, and other potential confounders.

Deep Dyspareunia: Review of Pathophysiology and Proposed Future Research Priorities
Orr N et al., 2020 · Sexual medicine reviews
Dyspareunia has been traditionally divided into superficial (introital) dyspareunia and deep dyspareunia (pain with deep penetration). While deep dyspareunia can coexist with a variety of conditions, recent work in endometriosis has demonstrated that coexistence does not necessarily imply causation. Therefore, a reconsideration of the literature is required to clarify the pathophysiology of deep dyspareunia. To review the pathophysiology of deep dyspareunia, and to propose future research priorities. A narrative review after appraisal of published frameworks and literature search with the terms (dyspareunia AND endometriosis), (dyspareunia AND deep), (dyspareunia AND (pathophysiology OR etiology)). Deep dyspareunia (present/absent or along a pain severity scale). The narrative review demonstrates potential etiologies for deep dyspareunia, including gynecologic-, urologic-, gastrointestinal-, nervous system-, psychological-, and musculoskeletal system-related disorders. These etiologies can be classified according to anatomic mechanism, such as contact with a tender pouch of Douglas, uterus-cervix, bladder, or pelvic floor, with deep penetration. Etiologies of deep dyspareunia can also be stratified into 4 categories, as previously proposed for endometriosis specifically, to personalize management: type I (primarily gynecologic), type II (nongynecologic comorbid conditions), type III (central sensitization and genito-pelvic pain/penetration disorder), and type IV (mixed). We also identified gaps in the literature, such as lack of a validated patient-reported questionnaire or an objective measurement tool for deep dyspareunia and clinical trials not powered for sexual outcomes. We propose the following research priorities for deep dyspareunia: deep dyspareunia measurement tools, inclusion of the population avoiding intercourse due to deep dyspareunia, nongynecologic conditions in the generation of deep dyspareunia, exploration of sociocultural factors, clinical trials with adequate power for deep dyspareunia outcomes, partner variables, female sexual response, pathways between psychological factors and deep dyspareunia, and personalized approaches to deep dyspareunia.

Deep Dyspareunia in Endometriosis: Role of the Bladder and Pelvic Floor
Orr NL et al., 2018 · The journal of sexual medicine
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, related to myofascial mechanisms or nervous system sensitization). This study aimed to determine whether bladder/pelvic floor tenderness and painful bladder syndrome were associated with severity of deep dyspareunia in women with endometriosis, regardless of Stage (I/II vs III/IV) or other endometriosis-specific factors. Observational study from a prospective patient registry (January 2014 to December 2016) at a tertiary centre for endometriosis. Included were women aged 18 to 49 years who had surgical removal and histopathologic confirmation of endometriosis at the centre. Cases with Stage I/II vs Stage III/IV endometriosis were analyzed separately. Bivariate associations with the primary outcome (severity of deep dyspareunia) were tested for bladder/pelvic floor tenderness, painful bladder syndrome, as well as endometriosis-specific factors identified at the time of laparoscopic surgery (eg, deep infiltrating endometriosis) and demographic factors (eg, age). Multivariable ordinal logistic regression was carried out to adjust for factors associated with the primary outcome. Primary outcome was severity of deep dyspareunia on an 11-point numeric rating scale, categorized as none/mild (0-3), moderate (4-6), and severe (7-10), from a preoperative self-reported questionnaire. Overall, 411 women had surgically confirmed endometriosis: 263 had Stage I/II and 148 had Stage III/IV endometriosis. Among women with Stage I/II endometriosis, severity of deep dyspareunia was associated with both bladder/pelvic floor tenderness and painful bladder syndrome (AOR = 1.94, 95% CI: 1.11-3.38, P = .019 and AOR = 1.99, 95% CI: 1.15-3.44, P = .013, respectively), independent of endometriosis-specific factors or other factors associated with deep dyspareunia severity. Similar associations were found in women with Stage III/IV endometriosis (bladder/pelvic floor tenderness AOR =2.51, 95% CI: 1.25-5.02, P = .01, painful bladder syndrome: AOR = 1.90, 95% CI: 1.01-3.57, P = .048). Myofascial or nervous system mechanisms may be important for deep dyspareunia in women with endometriosis, even in those with moderate-to-severe disease (Stage III/IV). Strengths include the prospective registry, and histological confirmation of endometriosis and staging by experienced endometriosis surgeons. Limitations include assessment of only one pelvic floor muscle (levator ani). In women with Stage I/II or Stage III/IV endometriosis, severity of deep dyspareunia was strongly associated with bladder/pelvic floor tenderness and painful bladder syndrome, independent of endometriosis-specific factors, which suggests the role of myofascial or sensitization pain mechanisms in some women with deep dyspareunia.
