Abstract
Three patients presenting with infertility were found to have low volume azoospermia. All 3 were taking sympatholytic medications; 2 were taking antipsychotics and 1 was taking an alpha-blocker. Low volume azoospermia may result from the use of sympatholytic medications, which cause aperistalsis of the adrenergically innervated vas deferens and seminal vesicles. Two patients had normal spermatogenesis on biopsy and were unobstructed on vasography. In 1 patient, biopsy and vasography were avoided. Pseudoephedrine, a sympathomimetic agent, was given to all 3 patients, resulting in marked improvement in semen analysis parameters. A trial of pseudoephedrine can obviate the need for biopsy and vasography in such patients.
