Hypoactive (Low) Sexual Desire Disorder
Persistently or recurrently deficient (or absent) sexual fantasies and desire for sexual activity. The judgment of deficiency or absence is made by the clinician, taking into account factors that affect sexual functioning, such as age and the context of the person's life.
The disturbance causes marked distress or interpersonal difficulty.
The sexual dysfunction is not better accounted for by another mental disorder (except another sexual dysfunction) and is not due exclusively to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
