Fifty infertile men with isolated asthenozoospermia and 30 fertile controls with normal semen parameters were included. Semen analysis was done with estimation of seminal plasma l-carnitine level. Scrotal ultrasonography was used as the diagnostic method for assessing epididymal morphology. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> Epididymal heterogeneous echogenicity was significantly higher in the infertile group compared to the controls. Whereas homogeneous epididymal echotexture and seminal plasma l-carnitine levels were significantly higher in the controls compared to the infertile patients. Interestingly, it was observed that within each group, seminal l-carnitine and sperm total motility were significantly higher in those with homogeneous rather than heterogeneous epididymal echotexture. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> Our study demonstrated a significant association between epididymal echo-texture, seminal plasma l-carnitine and sperm motility. Thus, we recommend performing epididymal sonographic evaluation as one of the basic investigations for infertile men. <\/jats:p><\/jats:sec>","DOI":"10.1177\/03915603241273886","type":"journal-article","created":{"date-parts":[[2024,9,14]],"date-time":"2024-09-14T04:04:21Z","timestamp":1726286661000},"page":"126-133","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Epididymal sonographic findings in infertile males with isolated asthenozoospermia and their correlation with seminal plasma l-carnitine: An observational study"],"prefix":"10.1177","volume":"92","author":[{"given":"Ahmed Mahmoud","family":"ElShibany","sequence":"first","affiliation":[{"name":"Department of Andrology, Sexology and STDs, Faculty of Medicine, Assiut University, Assiut, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emad Abd El Raheem","family":"Taha","sequence":"additional","affiliation":[{"name":"Department of Andrology, Sexology and STDs, Faculty of Medicine, Assiut University, Assiut, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dalia Tarek","family":"Kamal","sequence":"additional","affiliation":[{"name":"Department of Clinical Pathology, Faculty of Medicine, Assiut University, Assiut, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1918-5132","authenticated-orcid":false,"given":"Sameh Fayek","family":"GamalEl Din","sequence":"additional","affiliation":[{"name":"Department of Andrology, Sexology and STDs, Kasr Al-Ainy Faculty of Medicine, Cairo University, Giza, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasser Mohamed","family":"Abo El Yamen","sequence":"additional","affiliation":[{"name":"Andrology & STDs Department, Egypt Ministry of Health and Population, Egypt Ministry of Health and Population, Sohag, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hosam A","family":"Hasan","sequence":"additional","affiliation":[{"name":"Department of Radio-diagnosis, Faculty of Medicine, Assiut University, Assiut, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdel Rahman","family":"Bakry","sequence":"additional","affiliation":[{"name":"Department of Andrology, Sexology and STDs, Faculty of Medicine, Assiut University, Assiut, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,9,13]]},"reference":[{"key":"bibr1-03915603241273886","doi-asserted-by":"publisher","DOI":"10.2164\/jandrol.110.012351"},{"key":"bibr2-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2605.1999.00151.x"},{"key":"bibr3-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod.116.138768"},{"volume-title":"Human reproductive biology","year":"2013","author":"Jones RE","key":"bibr4-03915603241273886"},{"volume-title":"Gray\u2019s anatomy: the anatomical basis of clinical practice","year":"2016","author":"Standring S","key":"bibr5-03915603241273886"},{"key":"bibr6-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1530\/REP-13-0420"},{"issue":"6","key":"bibr7-03915603241273886","first-page":"211","volume":"2007","author":"Cornwall G","journal-title":"Genet Male Infertil"},{"key":"bibr8-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2017.05.023"},{"key":"bibr9-03915603241273886","first-page":"89","volume-title":"Male reproductive dysfunction","author":"Jones RC","year":"2007"},{"key":"bibr10-03915603241273886","first-page":"10","author":"Brooks D","year":"1979","journal-title":"Carnitine biosynthesis, metabolism and functions (USA)"},{"key":"bibr11-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1530\/jrf.0.0790523"},{"key":"bibr12-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1111\/andr.13062"},{"key":"bibr13-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2010.03.118"},{"key":"bibr14-03915603241273886","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2013.281053"},{"key":"bibr15-03915603241273886","unstructured":"World Health Organization.
