We investigated the effects of elated and depressed affect on sexual arousal in 15 sexually functional males. Subjects received elation and depression mood inductions in a repeated-measures design. Immediately following each induction, subjects viewed a brief erotic film during which penile tumescence and subjective sexual arousal were recorded continuously. Following depression induction there was a trend toward diminished subjective sexual arousal in the early portion of erotic exposure, and achievement of maximum subjective arousal was delayed; however, penile tumescence was unaffected. Multiple regression analysis indicated that tumescence during erotica was predictive of posterotica affect, independent of pre-erotica effect. The findings of delayed subjective arousal with no diminution in tumescence, although contrary to predictions, are consistent with previous research with sexually dysfunctional men. The study provides partial support for the role of depressed affect in the etiology of erectile dysfunction.
