Obesity and ED in males appear to be linked in many studies. Obesity is a significant risk factor for the progress of ED, which is a serious Clinical issue. This study was performed to assess the impact of weight loss induced by laparoscopic sleeve gastrectomy (LSG) on male sex hormones and erectile function among morbid obese male patients. The study was done over 32 morbidly obese married male cases who underwent LSG for weight reduction after doing assessments during their preoperative preparation. All subjects were evaluated by 4 questionnaires and serum hormone profiles pre-and postoperatively. Our study showed statistically significant improvement in the erectile function, and the Erection Hardness Score among morbid obese men undergoing LSG after 6 months of operation. Also showed statistically significant increasing levels of testosterone and decreasing levels of Estradiol (E2) after 6 months of operation. LSG is effective with significant enhancement of the Bariatric Quality of Life and Bariatric Body Image Satisfaction.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Graphical Abstract<\/jats:bold>\n                  <\/jats:p>","DOI":"10.1007\/s11695-025-08376-5","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T09:01:33Z","timestamp":1764838893000},"page":"98-104","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Influence of Laparscopic Sleeve Gastrectomy on Male Erectile Function among Morbid Obese Patients: an Observational Study"],"prefix":"10.1007","volume":"36","author":[{"given":"Mahmoud","family":"Azhary","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed H.","family":"Fahmy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed Mohammed Salah Eldeen Othman","family":"Elansary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ehab Fathy","family":"Ahmed","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed Ahmed","family":"AbdElSalam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed Eid","family":"Aziz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Elshal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed Maher Abd","family":"Elmonim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"8376_CR1","doi-asserted-by":"publisher","first-page":"1197","DOI":"10.1016\/S0140-6736(05)67483-1","volume":"366","author":"DW Haslam","year":"2005","unstructured":"Haslam DW, James WP.
