Responses of erectile tissue from impotent men to pharmacological agents
*Subscription may be required
Erectile tissue was removed from the corpora cavernosa of 25 impotent men undergoing surgery for insertion of penile prostheses. Strips, set up in an organ bath, were contracted by the alpha-adrenergic agonist phenylephrine. There was no significant difference between tissue taken from men with diabetes, alcoholism, Peyronie's disease or men with no obvious condition causing the impotence. The sensitivity of tissues from hypertensive patients was significantly reduced but this was probably due to drugs being taken for hypertension. Precontracted tissues could be relaxed by acetylcholine or isoprenaline. The responses, however, were inconsistent, so that no difference between the different groups of patients was apparent.
