A retrospective study of 217 cases of bovine freemartinism was made. Of these, 14 cases were diagnosed clinically, 141 were karyotyped and 62 were subjected to macroscopical examination of the reproductive tract. Of the 62 cases, 43 were assessed by measuring the reproductive organs (size and/or weight) and 41 were examined microscopically. Complete information on gross, histopathological and karyotyping analysis was available for only 10 animals. Freemartins showed reduced measurements of all reproductive organs. The mean lengths of vulva and vagina were 6.4 cm and 8.1 cm, respectively. Vesicular glands were observed in 30 freemartins. Histologically, these glands had more fibrous and less glandular tissue than the normal male vesicular glands. Uterine changes were variable, ranging from aplasia (two animals) to normal. Likewise, endometrial glands ranged from hypoplastic (decreased number and size) to normal. Glandular and myometrial cells showed prominent nuclei and less than normal cytoplasm, indicating a non-functional status. Gonadal size was reduced and an epididymis was present in seven animals. Rete ovarii were prominent and frequently occupied two-thirds of the gonad. Undifferentiated sex cords and abundant interstitial cells were salient features of the freemartin gonad. Oocytes were not observed. Ovarian follicles were seen in six cases. Karyotypic analyses demonstrated XY chimaerism in all freemartins.
