The histologic appearance of the ovaries and persistence of corpora lutea vary considerably among domestic animals, particularly between spontaneous and induced ovulators. The seasonally polyestrous mare has a variety of unique characteristics in ovarian structure and general reproductive function. Among the anomalies of ovarian development is the bovine freemartin with gonads containing a mixture of male and female elements. A variety of ovarian cysts occur in domestic animals, and persistent corpora lutea with associated reproductive perturbations occur in several species. Ovarian tumors are relatively uncommon in domestic animals, with most examples described in dogs, cats, and horses. These ovarian neoplasms are generally classified as epithelial, germ cell, or sex cord-stromal tumors.
家畜的卵巢组织学外观以及黄体的持续存在情况差异很大,特别是在自发排卵动物和诱导排卵动物之间。季节性多次发情的母马在卵巢结构和一般生殖功能方面具有多种独特特征。卵巢发育异常的情况包括牛的异性孪生母犊不育,其性腺含有雄性和雌性成分的混合物。家畜中会出现多种卵巢囊肿,并且在几个物种中会出现伴有相关生殖紊乱的持续性黄体。家畜中的卵巢肿瘤相对不常见,大多数病例见于犬、猫和马。这些卵巢肿瘤通常分为上皮性、生殖细胞性或性索间质肿瘤。
