The general anatomy of the reproductive organs in the jenny is similar to that of the mare. Some peculiarities of the anatomy
of the reproductive tract have been reported that may be of importance for the practising veterinarian. Donkey breeds present a wide variation in size and disposition. Miniature and small African breeds may be challenging as far as ''per rectum'' palpation
and ultrasonography of the reproductive organs. Techniques used for miniature horses may be adapted for the examination of these small individuals (Purdy, 2005; Tibary, 2004).

The jenny’s '''cervix is longer''' than that of the mare and is '''coneshaped'''. It protrudes into the vagina and forms a '''deeper fornix'''. This peculiarity makes manipulation of the cervix for uterine flushing or other techniques requiring access to the uterine cavity during dioestrus rather difficult. Also, the narrowness of the cervical canal may '''predispose to ''intra-partum'' or ''post-partum'' cervical laceration''' in cases of dystocia (Vendramini ''et al'', 1998). The '''vulvar lips are small and usually very tight'''. Pneumovagina and urovagina are not common.
