Sexual arousal disorder is characterized by a lack or absence of sexual fantasies and desire for sexual activity in a situation that would normally produce sexual arousal, or the inability to attain or maintain typical responses to sexual arousal. The disorder is found in the DSM-IV. The condition should not be confused with a sexual desire disorder. The term is often used in the diagnosis of women (female sexual arousal disorder), while the term erectile dysfunction (ED) is often used for men.
