IntroductionCycling can lead to microtrauma due to increased perineal pressure, possibly contributing to genital numbness and sexual dysfunction in female cyclists.AimWe aim to explore the associations between cycling characteristics, female genital numbness, and female sexual dysfunction.MethodsWe conducted a cross-sectional study on female cyclists and sexual wellness. Participants were recruited through Facebook® advertisements and online outreach at athletic clubs. Participants were asked about their cycling characteristics, genital numbness, and female sexual function using the Female Sexual Function Index (FSFI). Univariate and multivariable linear and logistic regression were used to assess risk factors for genital numbness and the association between genital numbness and the FSFI.Outcome measuresThe outcome measures were cycling characteristics, questions regarding numbness (intensity, duration, location), and the FSFI score.ResultsEight-hundred and seventy-five women were included in the study. Total lifetime miles cycled, biking duration, frequency, distance, speed, and biking surface were not significantly associated with genital numbness. Higher handlebar height was associated with less numbness. The prevalence of sexual dysfunction in the cohort was 52%. Genital numbness was significantly associated with sexual dysfunction (OR: 1.43, 95% CI: 1.05 - 1.95). Sub-group analysis for location of numbness demonstrated significant increase in risk for sexual dysfunction in cyclists who described numbness aro`und the perineum (OR: 2.72, 95% CI: 1.05 - 7.02) and the vulva (OR: 1.55, 95% CI: 1.13 - 2.13). There was also a significant increase in the risk of sexual dysfunction in cyclists who reported a longer duration of numbness (OR: 6.58, 95% CI: 2.27 - 19.07).ConclusionsGenital numbness is common in women who cycle and is associated with increased risk of FSD and lower average sexual response scores on FSFI.

BackgroundBicycle riding's impact on erectile function remains a topic of great interest given cycling's popularity as a mode of transportation and exercise.AimWe evaluated risk factors for sexual dysfunction in male cyclists with the primary intention of determining if genital/pelvic pain and numbness are associated with erectile dysfunction (ED).MethodsWe surveyed male cyclists using an online anonymous questionnaire. Cyclists were queried on their demographics, cycling experience, and sexual function using the Sexual Health Inventory for Men (SHIM). ED was diagnosed when a completed SHIM score was

IntroductionBicycle seat pressure on the perineum may impair arousal and clitoral erection, likely contributing to genital pain and numbness experienced by female cyclists.AimWe aimed to identify the association between genital pain and numbness experienced by female cyclists and female sexual dysfunction (FSD).MethodsFemale cyclists were recruited to complete an online survey using the Female Sexual Function Index (FSFI), a validated questionnaire to assess FSD. Cyclist demographics, experience, preferred riding style, use of ergonomic cycle modifications, and genital discomfort while riding were also queried. Multivariate logistic regression analysis was used to evaluate risk factors of FSD.Main outcome measuresThe main outcome was FSFI score, which is used to diagnose FSD when the FSFI score is

OBJECTIVE:To assess the association of genital numbness and erectile dysfunction in male cyclists. SUBJECTS AND METHODS:Cyclists were recruited through Facebook advertisements and outreach to sporting clubs. This is a secondary analysis of a larger epidemiological population-based study that examined sexual and urinary wellness in athletes. We queried cycling habits and erectile function using Sexual Health Inventory for Men (SHIM). RESULTS:A total of 2 774 male cyclists were included in the analysis. Amongst cyclists, there was a statistically significant increase in the trend of genital numbness presence with more years of cycling (P = 0.002), more frequent weekly cycling (P < 0.001), and longer cycling distance at each ride (P < 0.001). Less frequent use of padded shorts (odds ratio [OR] 0.14, P < 0.001) and lower handlebar (OR 0.49, P < 0.001) were associated with numbness, but body mass index (BMI) (OR 1.1, P = 0.33) and age (OR 1.2, P = 0.15) were not. In a multivariate logistic regression model, after adjusting for age, BMI, and lifetime miles (calculated by average daily cycling mileage × cycling days/week × cycling years.), there were no statistically significant differences in mean SHIM score between cyclists with and cyclists without numbness (20.3 vs 20.2, P = 0.83). However, interestingly, the subset of cyclists who reported numbness in the buttock reported statistically significantly worse SHIM scores (20.3 vs 18.4, P < 0.001). This association was not present in cyclists who reported numbness in the scrotum, penis, or perineum and remained significant after adjusting for overall biking intensity. CONCLUSION:Cyclists report genital numbness in proportion with biking intensity but numbness is not associated with worse sexual function in this cohort.

In this comprehensive review, the intricate relationship between paternal factors and pregnancy loss is examined. While pregnancy loss has historically been predominantly attributed to maternal factors, recent research underscores the significant contribution of the male partner. The review delves into various aspects of paternal influence, including paternal age, health, chromosome abnormalities, Y chromosome deletions, and sperm DNA fragmentation. Notably, advanced paternal age is found to be associated with an increased risk of recurrent pregnancy loss, shedding light on the importance of understanding the impact of aging on male fertility. Additionally, paternal health, particularly metabolic syndrome, emerges as a noteworthy factor contributing to pregnancy loss. Chromosome abnormalities in male partners, such as balanced translocations, and Y chromosome microdeletions are explored in the context of pregnancy loss risk. Moreover, the review highlights the growing body of evidence linking sperm DNA fragmentation and sperm protein abnormalities to spontaneous pregnancy loss, emphasizing the significance of sperm health in reproductive outcomes. Overall, this review provides a comprehensive overview of the multifaceted role of the male partner in pregnancy loss, calling for a more inclusive approach to pregnancy loss investigations that encompasses both maternal and paternal factors.

BACKGROUND:Bicycle riding has become an increasingly popular mode of transportation and exercise, especially among women, and previous studies have demonstrated a relationship between cycling and sexual dysfunction, albeit using non-validated questionnaires. AIM:We aimed to explore the relationship between cycling and sexual and urinary dysfunction. METHODS:Cyclists were recruited to complete a survey through Facebook advertisements and outreach to sporting clubs across 5 English-speaking countries. Swimmers and runners were recruited as a comparison group. OUTCOMES:Participants were queried using validated questionnaires, including the Female Sexual Function Index, the American Urological Association Symptom Index, and non-validated questions about history of urinary tract infections (UTIs), genital numbness, and genital saddle sores (all self-reported). RESULTS:3,118 (53.3%) Women completed the survey, comprising 1,053 (34%) non-cyclists, 1,656 (53%) low-intensity cyclists, and 409 (13%) high-intensity cyclists. After adjusting for age, body mass index, hypertension, diabetes, ischemic heart disease, tobacco use, race, marital status, urinary symptoms, and sexual activity, high-intensity cyclists had lower odds of self-reported sexual dysfunction compared to non-cyclists (adjusted odds ratio [aOR] 0.7, P = .02). There were no statistically significant differences in urinary symptoms across groups. Compared to non-cyclists, both low- and high-intensity cyclists had higher odds of reporting a previous UTI (aOR 1.4, P < .001, and aOR 1.4, P = .009, respectively), genital numbness (odds ratio [OR] 6.5, P < .001, and OR 9.1, P < .001, respectively), and saddle sores (OR 6.3, P < .001, and OR 22.7, P < .001, respectively). CLINICAL TRANSLATION:Women cyclists were more likely to report other genitourinary conditions, including UTIs, genital numbness, and saddle sores. CONCLUSIONS:This is the largest study comparing cyclists to other athletes with respect to sexual and urinary function. The study is limited by its cross-sectional design and sampling methods. We found that women cyclists were no more likely to report sexual dysfunction or urinary symptoms than swimmers or runners. Gaither TW, Awad MA, Murphy GP, et al.

PURPOSE:We explored the relation of cycling to urinary and sexual function in a large multinational sample of men. MATERIALS AND METHODS:Cyclists were recruited to complete a survey through Facebook® advertisements and outreach to sporting clubs. Swimmers and runners were recruited as a comparison group. Cyclists were categorized into low and high intensity cyclists. Participants were queried using validated questionnaires, including SHIM (Sexual Health Inventory for Men), I-PSS (International Prostate Symptom Score) and NIH-CPSI (National Institutes of Health Chronic Prostatitis Symptom Index), in addition to questions about urinary tract infections, urethral stricture, genital numbness and saddle sores. RESULTS:Of 5,488 complete survey responses 3,932 (72%) were included in our analysis. On multivariate analysis swimmers/runners had a lower mean SHIM score than low and high intensity cyclists (19.5 vs 19.9 and 20.7, p = 0.02 and
