Partial Ejaculatory Incompetence: the Therapeutic Effect of Midodrine1, an Orally Active Selective Alpha-Adrenoceptor Agonist

Abstract
The syndrome of partial ejaculatory incompetence has been reviewed. 6 patients, diagnosed as suffering from partial ejaculatory incompetence, were studied. For each subject, large numbers of spermatozoa were present in the post-masturbation urine sample providing evidence of disturbed ejaculatory function. The effect of a potent alpha-adrenoceptor agonist (Midodrine) was evaluated in these patients by means of a double-blind crossover study. Active treatment resulted in a significant increase in intensity of orgasmic sensation, and in a statistically significant improvement in ejaculatory function.
