Uterotubal junction (UTJ) was dissected from 8 cows and 12 camels with dominant follicles, and processed for H&amp;E staining for histology, and histomorphometry examination. The results showed that the camel uterotubal junction papillae (UTJP) existed only in camels and was completely absent in cattle. Histologically, the cow UTJ appears with a star\u2010shaped lumen, and the mucosa is lined by a simple columnar epithelium with ciliated and non\u2010ciliated cells. Superficial (SG) and deep glands (DG) were abundant in the submucosa. Camel UTJP is a conical structure, it has a pale yellowish colour, 0.5\u2009\u00b1\u20090.2\u2009cm height, and 0.3\u2009\u00b1\u20090.1\u2009cm width, and it has a distinct sphincter at the tip towards the uterine lumen. In the camel UTJP, the lumen is wider, and the mucosa showed large multiple folds lined with ciliated and non\u2010ciliated cells in a pseudostratified columnar epithelium. The submucosa showed no mucosal glands. Lumen area, lumen epithelial height, luminal epithelial density, the thickness of the muscular layer, number of folds, fold height, epithelial height, fold area and epithelial perimeter were higher in camel UTJP (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) than cow UTJ, while the total endosalpinx area and glandular epithelial density were lower in camel UTJP (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) than in cow UTJ. In conclusion, this study elucidates potential variations in the uterotubal junction between bovines and dromedary camels, providing valuable insights into their reproductive adaptations. The epithelial lining, absence of glands and the thick layer of tunica muscularis might indicate that camel UTJP could play a mechanical role in selecting spermatozoa and assisting the hatching of blastocysts during their passage into the uterus.<\/jats:p>","DOI":"10.1111\/rda.14665","type":"journal-article","created":{"date-parts":[[2024,7,8]],"date-time":"2024-07-08T10:45:36Z","timestamp":1720435536000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Uterotubal junction of the bovine (<i>Bos taurus<\/i>) versus the dromedary camel (<i>Camelus dromedarius<\/i>): Histology and histomorphometry"],"prefix":"10.1111","volume":"59","author":[{"given":"Ahmed Sabry S.","family":"Abdoon","sequence":"first","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination Veterinary Research Institute, National Research Centre  Cairo Dokki Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seham S.","family":"Soliman","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination Veterinary Research Institute, National Research Centre  Cairo Dokki Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed M.","family":"Nagy","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination Veterinary Research Institute, National Research Centre  Cairo Dokki Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,8]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2016.11.033"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrd.23350"},{"key":"e_1_2_9_4_1","first-page":"743","article-title":"The mammalian oviductal epithelium: Regional variations in cytological and functional aspects of the oviductal secretory cells","volume":"11","author":"Abe H.","year":"1996","journal-title":"Histology and Histopathology"},{"issue":"1","key":"e_1_2_9_5_1","first-page":"1","article-title":"Evaluation of the morphological features of the uterine tubes during postnatal development in west African dwarf goats (Capra hircus)","volume":"8","author":"Abiaezute C.
