Sensory conduction velocity of dorsal nerve of the penis during pharmacoerection: a more physiological technique?

Objective: Sensory conduction velocity (SCV) of the dorsal nerve of the penis is technically difficult to perform at rest and very slow SCV has been observed in the literature. This study evaluates the effect of pharmacoerection on the SCV measurement.

Methods: Twenty-four men, 16 with a normal neurologic examination, 8 with a diabetic neuropathy, were studied at rest and after a 20-micrograms injection of prostaglandin E1.

Cavernous oxygen tension and smooth muscle fibers: relation and function.

Purpose: We studied the effect of intracavernous oxygen tension on the alteration of cavernous smooth muscle fibers in potent and impotent men.

Materials And Methods: Intracavernous oxygen tension (mm. Hg) was measured during flaccidity and 10 minutes after intracavernous prostaglandin E1 injection in psychogenic control patients, and those with venous leakage and arterial lesions.
