This is a secondary analysis of a larger epidemiological population\u2010based study that examined sexual and urinary wellness in athletes. We queried cycling habits and erectile function using Sexual Health Inventory for Men (\n SHIM<\/jats:styled-content>\n ).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 2\u00a0774 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 (\n P<\/jats:italic>\n = 0.002), more frequent weekly cycling (\n P<\/jats:italic>\n < 0.001), and longer cycling distance at each ride (\n P<\/jats:italic>\n < 0.001). Less frequent use of padded shorts (odds ratio [\n OR<\/jats:styled-content>\n ] 0.14,\n P<\/jats:italic>\n < 0.001) and lower handlebar (\n OR<\/jats:styled-content>\n 0.49,\n P<\/jats:italic>\n < 0.001) were associated with numbness, but body mass index (\n BMI<\/jats:styled-content>\n ) (\n OR<\/jats:styled-content>\n 1.1,\n P<\/jats:italic>\n = 0.33) and age (\n OR<\/jats:styled-content>\n 1.2,\n P<\/jats:italic>\n = 0.15) were not. In a multivariate logistic regression model, after adjusting for age,\n BMI<\/jats:styled-content>\n , and lifetime miles (calculated by average daily cycling mileage \u00d7 cycling days\/week \u00d7 cycling years.), there were no statistically significant differences in mean\n SHIM<\/jats:styled-content>\n score between cyclists with and cyclists without numbness (20.3 vs 20.2,\n P<\/jats:italic>\n = 0.83). However, interestingly, the subset of cyclists who reported numbness in the buttock reported statistically significantly worse\n SHIM<\/jats:styled-content>\n scores (20.3 vs 18.4,\n P<\/jats:italic>\n < 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.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Cyclists report genital numbness in proportion with biking intensity but numbness is not associated with worse sexual function in this cohort.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/bju.14396","type":"journal-article","created":{"date-parts":[[2018,5,23]],"date-time":"2018-05-23T05:09:44Z","timestamp":1527052184000},"page":"336-341","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The association of bicycle\u2010related genital numbness and Sexual Health Inventory for Men (\n SHIM<\/scp>\n ) score: results from a large, multinational, cross\u2010sectional study"],"prefix":"10.1111","volume":"124","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4332-8017","authenticated-orcid":false,"given":"Nima","family":"Baradaran","sequence":"first","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohannad","family":"Awad","sequence":"additional","affiliation":[{"name":"Department of Surgery King Abdulaziz University Rabigh Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas W.","family":"Gaither","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kirkpatrick B.","family":"Fergus","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Medina","family":"Ndoye","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin E.","family":"Cedars","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashwin S.","family":"Balakrishnan","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael L.","family":"Eisenberg","sequence":"additional","affiliation":[{"name":"Department of Urology Stanford University School of Medicine San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tom","family":"Sanford","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin N.","family":"Breyer","sequence":"additional","affiliation":[{"name":"Department of Urology University of California San Francisco San Francisco CA USA"},{"name":"Department of Biostatistics and Epidemiology University of California San Francisco San Francisco CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,6,7]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"Statista.Number of Cyclists\/Bike Riders in the U.S. The Statistics Portal.
