The arterial vascularization of agoutis' penis (Dasyprocta prymnolopha) were analysed using ten male adults from 'Núcleo de Estudos e Preservação de Animais Silvestres da Universidade Federal do Piauí' (FUFPI/IBAMA n degrees 02/99). Among the total number of specimens, six animals had natural death and were members of the research collection of the Laboratory of Anatomy, and four were killed after anaesthesia. Stained bi-centrifugated-Cis-I-4 latex was injected in arterial vessels responsible for penis vascularization throughout the abdominal portion of aorta. The samples were fixed in 10% formaldehyde solution and arteries were dissected. The penile artery is originated as a branch of internal pudendal artery. At the level of ischiatic arch, the penile artery project two branches, the penile dorsal and the deep arteries; those arteries irrigates the penile dorsal surface and the corpus cavernosum penis. The penile dorsal arteries have an independent course up to the glans penis. Based on the conditions of this work a remarkable similarity regarding the distribution of vessels destined to the agouti penis when compared to other domestic, wild and lagomorph rodents as rabbits.
使用来自“皮奥伊联邦大学野生动物研究与保护中心”（FUFPI/IBAMA第02/99号）的10只成年雄性刺豚鼠（Dasyprocta prymnolopha），对其阴茎的动脉血管分布进行了分析。在所有标本中，6只动物自然死亡，是解剖学实验室研究标本的一部分，4只在麻醉后被处死。将经双离心处理的Cis-I-4乳胶注入负责阴茎血管分布的主动脉腹部段的动脉血管中。样本固定于10%甲醛溶液中，然后解剖动脉。阴茎动脉起源于阴部内动脉的一个分支。在坐骨弓水平，阴茎动脉分出两个分支，即阴茎背动脉和阴茎深动脉；这些动脉为阴茎背表面和阴茎海绵体供血。阴茎背动脉在到达阴茎头之前有独立的走行。基于本研究的情况，与其他家养、野生和兔形目啮齿动物（如兔子）相比，刺豚鼠阴茎血管分布有显著相似性。
