RESEARCH OPINIONS IN ANIMAL & VETERINARY SCIENCES Diphallia and double scrota in a donkey: A case report

Diphallia and double scrota are rare congenital anomalies. This report records, for the first time, the gross pathological findings of a rare case of diphallia and double scrota in a two-year-old donkey. On physical examination of the donkey, double peni, double prepuces, double scrota and two testes were observed. The two peni were directed opposite to each other at the caudal ventral midline. The posterior penis was the functional one and appeared normal in structure. This penis had ventral deviation and was displaced caudally to the posterior scrotum and testes. The testes were atrophied, asymmetrical and located anterior to the posterior penis in a transverse plan. The anterior penis was not functional, rudimentary, replaced by a fibrous band, fixed to the prepuce and had normal cranial direction. The anterior prepuce was well developed with preputial orifice. The anterior scrotum was rudimentary, empty and located posterior to the anterior penis. Two rudimentary teats were also seen between anterior prepuce and scrotum.
