Arterial and venous flow and pressure studies of the corpora cavernosa were performed to elucidate the hemodynamics of canine penile erection. Being able to induce erection by electrical stimulation we were able to study the functionally relevant parameters at different stages of penile erection. From our results we conclude that penile erection can be subdivided in 5 phases: (1) latent-, (2) tumescence-, (3) erection-, (4) rigidity- and (5) detumescence phase. Furthermore, a differentiation of these subdivisions is made by observing at the mechanism of the 5 different stages: phase 1 to 4 is an active phenomenon, the detumescence phase is passive only.
为阐明犬阴茎勃起的血流动力学，对阴茎海绵体进行了动脉和静脉血流及压力研究。由于能够通过电刺激诱导勃起，我们得以研究阴茎勃起不同阶段的功能相关参数。根据我们的研究结果，我们得出结论：阴茎勃起可分为五个阶段：(1) 潜伏期，(2) 肿胀期，(3) 勃起期，(4) 坚硬期和(5) 消退期。此外，通过观察这五个不同阶段的机制对这些细分阶段进行了区分：第1至4阶段是主动现象，消退期仅是被动现象。
