[Depression and sexual dysfunction: aspects of a multi-faceted relationship].

For the psychiatrist the association between depression and sexual dysfunction is of major importance since both affective and sexual disorders are highly prevalent and exhibit a marked co-morbidity. A high percentage of men and women suffering from depression reports sexual problems. In women, sexual desire is predominantly affected while in men both desire and erectile function tend to be impaired. However, the relationship between depressive mood and sexual dysfunction is bidirectional and further complicated by the sexual side effects of antidepressants which most often affect sexual arousal and orgasmic function. As a consequence, the sexual sphere should be adequately and routinely addressed in the assessment and treatment of all depressive patients.
