The current study was conducted to address the pathological conditions of ovaries of cows

slaughtered at the abattoir in Sulaimani province, Kurdistan Region-Iraq. Among the 404

genitalia samples collected from the non-pregnant animals, 206 (51%) were found without

gross pathological abnormalities (with cyclic activity) and the remaining

120(29.70%)samples were found with gross pathological abnormalities of ovaries. The

ovaries exhibited the highest percentage of lesions 29.70%. Detected ovarian lesions

included follicular cyst 10.89%, cystic corpus luteum 5.44%, mild ovariobursal adhesions

4.45 %, sever ovariobursal adhesion 0.25%, paraovarian cysts 3.22%, ovarian hypoplasia

1.98%, ovarian hemorrhage (hemorrhagic cystic corpus luteum) 1.48%, luteal cyst 1.24%,

ovarian agenesis 0.50% and ovarian tumor (Gonadoblastoma) 0.25%. Histopathological

examinations exhibited that the follicular cysts were lined by several layers of granulosa

and theca cell, while the luteal cysts had follicular granulsa and the theca cells with marked

luteinization of cytoplasm. Microscopically, the ovarian hypoplasia showed lack of

ovarian follicles and oocytes, while the cavities of paraovarian cysts were lined by a single

layer of cuboidal epithelial cells, and the hemorrhagic cyst showed scattered hemorrhagic

spots close to the lumen and luteinized of granulosa and theca cells layers of cystic wall.

Histopathologically, the ovarian gonadoblastoma (Dysgenentic gonadoma) was

characterized by dual population of germ cell tumor and sex-cord stromal tumor and this

observation has not been recorded in Iraq previously. It was concluded that ovarian

abnormalities constitutes an percentage 0f 29.70%. And ovarian gonadoblastoma was

firstly recorded in this study in Iraq.
