They are also susceptible to a range of insults, and pathology of these structures is a common cause of infertility in both <jats:styled-content style=\"fixed-case\"><jats:italic>Bos taurus<\/jats:italic><\/jats:styled-content> and <jats:styled-content style=\"fixed-case\"><jats:italic>Bos indicus<\/jats:italic><\/jats:styled-content> bulls. Significant individual and breed\u2010based variation occurs in the looseness of the skin, the presence and development of preputial muscles, the relative position of the opening to the cranial preputial muscles, the length of the prepuce, and the prominence of the umbilicus. Individual and breed\u2010based susceptibility to different conditions is associated with these anatomical variations. Regardless of the cause, pathology of the prepuce generally results in sepsis, prolapse, stenosis or adhesions or a combination. Clinical examination should be aimed at determining the extent of these processes and the amount of healthy prepuce which would remain following successful treatment. The inclusion of evaluation of sheath conformation in the form of a sheath score is recommended. Current scoring systems do not reflect the diversity of predisposing factors to morbidity and may therefore fail to accurately reflect the risk of morbidity. A more detailed scoring system has been proposed. Further refinement of this system is outlined, consisting of a composite of scores for depth, umbilical skin fold, prepuce eversion, and distance from cranial muscle to opening (the \u2018Y\u2019 factor). Validation against actual bull performance is indicated to develop a valid and useful risk\u2010management tool for use in evaluating sheath conformation.<\/jats:p>","DOI":"10.1111\/avj.12900","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T19:23:25Z","timestamp":1575314605000},"page":"48-52","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Applied anatomy, pathophysiology and a revised scoring system of bull sheaths"],"prefix":"10.1111","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7374-9720","authenticated-orcid":false,"given":"Peter\u2009Charles","family":"Irons","sequence":"first","affiliation":[{"name":"College of Science, Health, Engineering and Education, Murdoch University School of Veterinary Medicine  Murdoch Western Australia 6150 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,12]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"201","volume-title":"Large animal urogenital surgery","author":"Beckett SD","year":"1998"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1079\/9781780643168.0297"},{"key":"e_1_2_9_4_1","first-page":"5","volume-title":"Bovine reproduction","author":"Nabors B","year":"2015"},{"volume-title":"Dyce, Sack and Wensing's textbook of veterinary anatomy","year":"2018","author":"Singh B","key":"e_1_2_9_5_1"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0034-5288(18)34152-3"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1079\/9781780643168.0352"},{"volume-title":"Ruminant urogenital surgery","year":"1987","author":"Hofmeyr CFB","key":"e_1_2_9_8_1"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-4320(02)00023-4"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/vr.86.6.161"},{"key":"e_1_2_9_11_1","first-page":"9","article-title":"Epidemiological aspects of surgical diseases of the genital tract in a popultion of 12 320 breeding bulls (1982\u20132007) in the state of Goias, Brazil","volume":"9","author":"Rabelo RE","year":"2008","journal-title":"Cien Anim Brazileira"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2007.06.013"},{"volume-title":"Bull breeding soundness evaluation","year":"2000","author":"Barth A","key":"e_1_2_9_13_1"},{"volume-title":"Veterinary bull breeding soundness evaluation","year":"2013","author":"Beggs DS","key":"e_1_2_9_14_1"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-0720(15)30341-8"},{"volume-title":"Evaluation of bulls for breeding soundness","year":"2007","author":"Parkinson T","key":"e_1_2_9_16_1"},{"volume-title":"Society for theriogenology manual for breeding soundness examination of bulls","year":"2018","author":"Koziol JH","key":"e_1_2_9_17_1"},{"key":"e_1_2_9_18_1","unstructured":"BeggsDS editor.Survey of BullReporter II results.
