Antipsychotic drug therapy and sexual dysfunction in men.

The authors review the literature on male sexual dysfunction associated with antipsychotic drug treatment. Erectile and ejaculatory disturbances have been most frequently reported. Changes in libido have also been reported, but the effects of these drugs on sexual drive have apparently not been systematically studied. Fortunately, most types of sexual dysfunction associated with antipsychotic drugs appear to be medically benign and reversible with drug discontinuation. An exception is priapism, which necessitates prompt urological consultation and may require surgical intervention.
