Thirteen patients with normal nocturnal erections and penile pressures were studied in the flaccid penis by Doppler technique. In eleven, compression of a dorsal penile artery caused occlusion of the pulse wave distally over this vessel and also the disappearance of the presumed pulse of the deep cavernosal artery. It is postulated that in the nonerect… (More)
The physiology of normal erection is contrasted to that induced by artificial perfusion. The diagnostic value of the procedure is limited. Perfusion may be useful in monitoring the effect of drugs instilled into the penis or in choice of procedure.
The dorsal and cavernous arteries of the penis in 14 cadavers and 4 surgical specimens were studied, and the role of these vessels in producing erection was evaluated. For the first time, erection was produced in a cadaver by the perfusion of the cavernous artery. Perfusing the dorsal artery resulted in distention but not erection, and the dorsal artery… (More)
We describe the modular synthesis of three novel large N-heteroarenes, containing 9, 11, and 13 annulated rings. This modular system features fused azaacene units to a coronene nucleus. We evaluate the optical and electronic properties and the solid-state packing of the targets. The electronic properties of the 13-ring N-heteroarene allow the fabrication of… (More)
The use of prostaglandin E1 is introduced as a pharmacologic agent that can produce artificial erections in patients who have failed the initial papaverine test or who were on self-injection programs and later lost rigidity.
