Although donkeys play an important role as companion or pack and draught animals, theriogenological studies and anatomical data on the genital organs of the jenny are sparse. To provide anatomical descriptions and morphometric data, the organa genitalia feminina, their arteries and the ligamentum latum uteri of 10 adult but maiden jennies were examined by means of gross anatomical and morphometric techniques. In comparison with anatomical data of horses obtained from literature the genital organs of jennies appear to be more voluminous in relation to the body mass and the position of the ovaries is slightly further cranial than in mares. In asses, the ovaries contain large follicles reaching a diameter of up to 40 mm. The mesosalpinx is much wider than in the horse forming a considerably spacious bursa ovarica. The asinine ligamentum teres uteri reveals a very prominent cranial end, the 'appendix'. Tortuous mucosal folds occur in the wall of the jenny's cervical channel. The vascularization of the female genital organs of asses is very similar to that of horses. One of the examined specimens reveals a large mucosal fold dividing the cranial part of the vagina into a left and right compartment.
尽管驴作为伴侣动物或驮畜及役畜发挥着重要作用，但关于母驴生殖器官的生殖学研究和解剖学数据却很稀少。为了提供解剖学描述和形态测量数据，采用大体解剖学和形态测量技术对10头成年但未孕母驴的雌性生殖器官、其动脉及子宫阔韧带进行了检查。与从文献中获得的马的解剖学数据相比，母驴的生殖器官相对于体重似乎更大，且卵巢的位置比母马的略更靠前。在驴中，卵巢含有直径可达40毫米的大型卵泡。输卵管系膜比马的宽得多，形成一个相当宽敞的卵巢囊。驴的子宫圆韧带显示出一个非常突出的头端，即“附件”。母驴宫颈管的壁上出现曲折的黏膜皱襞。驴的雌性生殖器官的血管分布与马的非常相似。其中一个被检查的标本显示有一个大的黏膜皱襞将阴道的头部分为左右两个腔室。
