Provoked priapism in sickle cell anemia.

Two patients with sickle cell anemia are reported who developed relative impotence after repeated episodes of priapism. They learned that excessive ethanol ingestion produced an erection and utilized this mechanism to satisfy sexual partners. Hospitalization and transfusion therapy were required for repeated episodes of priapism. Extensive interviews were required in order to learn the sequence of events. This synergistic relationship between ethanol and priapism should be sought in patients with repeated hospitalizations for this complication of sickle cell anemia because it is preventable with appropriate counseling.
