Sexual desire disorder is a psychiatric condition marked by a lack of desire for sexual activity over a prolonged period. In the DSM-5, Sexual Desire Disorder has been broken down into two separate conditions: Female Sexual Interest/Arousal Disorder and Male Hypoactive Sexual Desire Disorder. Both of these refer to a low level of sexual interest resulting in a failure to initiate or respond to sexual intimacy. This can include an absence of sexual thoughts or fantasies, reduced or absent pleasure during sexual activity, and absent or reduced interest in internal or external erotic cues. Neither of these conditions can be diagnosed if the main problem is a "desire discrepancy" in which one partner desires more sexual activity than the other; rather, the conditions are diagnosed when symptoms have been present for a minimum of six months and cause clinically significant distress for the individual.
Female Sexual Interest/Arousal Disorder and Male Hypoactive Sexual Desire Disorder can both be diagnosed as generalized, meaning they may be a general attitude toward any potential partner or situation. These conditions can also be diagnosed as being situational, meaning symptoms are only present with certain types of stimulation, situations, or partners. Female Sexual Interest/Arousal Disorder was known as Sexual Arousal Disorder in previous versions of the DSM, although this diagnosis has been replaced by gender-specific conditions in the DSM-5.
The prevalence of Female Sexual Interest/Arousal Disorder is unknown, although some older women report less distress about experiencing low sexual desire than younger women. In men, it is estimated that 6 percent of younger men (ages 18-24) and 41 percent of older men (ages 66-74) have some problems with sexual desire. Only 1.8 percent of men ages 16-44, however, experience persistent problems lasting more than six months.
