title: Reversible loss of nocturnal penile tumescence during depression: a preliminary report.
abstract: Depressed patients regularly report a loss of interest in sex, but whether this represents only a lack of psychological motivation or is a reflection of an underlying physiological abnormality is unknown. We have studied 2 men suffering from severe depression and have observed that nocturnal penile tumescence was virtually absent while the men were depressed but returned to normal on recovery.
