In the present work, the accessory sex organs of 60 Egyptian jacks were classified according to their age into young (<jats:italic>n<\/jats:italic>\u2009=\u200915), adult (<jats:italic>n<\/jats:italic>\u2009=\u200925) and senile (<jats:italic>n<\/jats:italic>\u2009=\u200920). Jacks were euthanized and the accessory sex organs were immediately separated and collected. Morphometric measures of the penis, ampulla, seminal vesicles, prostate and bulbourethral gland, including length and weight, were determined. Tissue samples from the ampulla, seminal vesicles, prostate and bulbourethral glands were collected, processed and stained with H&amp;E for histomorphometric examination. Our findings reveal significant age\u2010related alterations in the penial weight and length, the structure and secretory activity of the accessory sex glands, shedding light on the physiological changes that occur with advancing age in this species. Insights gained from this analysis can improve reproductive management practices and contribute to the conservation of donkey populations.<\/jats:p>","DOI":"10.1111\/rda.70082","type":"journal-article","created":{"date-parts":[[2025,5,26]],"date-time":"2025-05-26T07:49:24Z","timestamp":1748245764000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Age\u2010Related Changes in Accessory Sex Organs of Egyptian Jacksassess (<i>Equus asinus<\/i>): A Morphometric and Histological Study"],"prefix":"10.1111","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8430-9325","authenticated-orcid":false,"given":"Ahmed Sabry S.","family":"Abdoon","sequence":"first","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination, Veterinary Research Institute National Research Centre  Dokki Cairo Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Afaf A.","family":"Kishta","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Veterinary Medicine University of Sadat City  Sadat Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nazema S.","family":"Abdel\u2010Megeid","sequence":"additional","affiliation":[{"name":"Department of Histology, Faculty of Veterinary Medicine University of Sadat City  Sadat Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shenming","family":"Zeng","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology China Agricultural University  Beijing China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Said I.","family":"Fathalla","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Veterinary Medicine University of Sadat City  Sadat Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sherif M.","family":"Shawky","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Veterinary Medicine University of Sadat City  Sadat Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Igor F.","family":"Canisso","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Medicine, College of Veterinary Medicine University of Illinois Urbana\u2010Champaign  Urbana Illinois USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9085-8646","authenticated-orcid":false,"given":"Shimaa R.","family":"Masoud","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Veterinary Medicine University of Sadat City  Sadat Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,26]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"126","article-title":"Histological and Histochemical Studies on the Seminal Vesicles of Donkey (Equus asinus): With Special Reference to Their Seasonal Variations","volume":"10","author":"Abou\u2010Elhamd A.
