Dealing with the subject "polled goats intersexuality", whose problems are discussed, we studied the pathology of 7 3-month old XX-kids: 2 pseudomales, 3 males with urethral diverticulum (1 animal with 2 U.D.), and 2 testicular pseudohermaphrodites. Four horned male kids of comparable age were used as control. Urethral diverticula, seen now and then in local breeds, i.e. in "chamois-colored" mountain goats, Saanen, and Toggenburg goats, are rather unknown and only sporadically reported abroad. In agreement with previous histological studies, the testes were hypoplastic, the spermatogonia absent. In no case ovarian tissue was found. The Leydig cells appeared to be functionally active. The selection of an experimental flock of intersex-free polled goats is proposed.
在探讨“无角山羊雌雄间性”这一主题及其相关问题时,我们研究了7只3月龄XX幼羊的病理学情况:2只假雄性、3只患有尿道憩室的雄性(其中1只动物有2个尿道憩室)以及2只睾丸性假两性畸形羊。选取了4只年龄相仿的有角雄性幼羊作为对照。尿道憩室在本地品种中时有出现,比如在“麂皮色”山地山羊、萨能山羊和吐根堡山羊中,但在国外鲜为人知,仅有零星报道。与先前的组织学研究一致,这些羊的睾丸发育不全,精原细胞缺失。未发现卵巢组织。间质细胞看起来功能活跃。建议挑选一群无雌雄间性的无角山羊作为实验群体。
