Abstract
Vasoactive intestinal polypeptide (VIP) hits been suggested to play a role as a nonadrenergic, noncholinergic neurotransmitter or neuromodul ator involved in the process of erection. Until now, data about fluctu ating concentrations of VIP in corpus cavernosum (CC) blood have been controversial. The present study describes a modified radioimmunoassay method that was developed in our laboratory for the determination of VIP in plasma. Examination of 12 patients suffering from impotentia co eundi (6 men with psychogenic impotence, 2 with induratio penis plasti ca, and 4 with impotence of vascular origin) showed that the concentra tions of VIP in corpus cavernosum blood during pharmacologically induc ed erection did not increase in organically healthy men or in men with impotentia coeundi of vascular origin. The VIP concentrations in peri pheral venous blood and those in CC blood were similar.
