Vascularização arterial do sistema genital masculino de cutia (Dasyprocta prymnolopha) / Arterial supply of the male genital system of agouti (Dasyprocta prymnolopha)

ABSTRACT

The arterial vascularization of the male genital system of agouti (Dasyprocta prymnolopha) wasanalysed using one male adults from 'Núcleo de Estudos e Preservação de Animais Silvestres from UniversidadeFederal do Piauí. Red Neoprene latex was injected through the heart’s left ventricle, the sample was fixed in10% formaldehyde solution and arteries were dissected. The blood vessels were photographed using digitalcamera, Sony DSC-H10. The testicular artery, originated from the ventral portion of the abdominal aorta,between the renal arteries and caudal mesenteric arteries, is responsible for the vascularization of the testes, vasdeferens and epididymis. The penile artery, originated from the internal pudendal artery, performs the arterialsupply for penis. The arterial vascularization of the reproductive organs of agouti is similar to those ofcarnivores (dogs), rodent nutria and domestic rabbits.
