Hypersexuality is extremely frequent or suddenly increased sexual urges or sexual activity. Although hypersexuality can be caused by some medical conditions or medications, in most cases the cause is unknown. Mental health problems such as borderline personality disorder can give rise to hypersexuality, and alcohol and some drugs can affect social and sexual inhibitions in some people. A number of theoretical models have been used to explain or treat hypersexuality. The most common one, especially in the popular media, is the sexual addiction approach, but sexologists have not reached any consensus. Alternative explanations for the condition include compulsive and impulsive behavioral models.
The International Classification of Diseases (ICD-10) of the World Health Organization includes "Excessive Sexual Drive" (coded F52.7)—which is divided into satyriasis for males and nymphomania for females—and "Excessive Masturbation" (coded F98.8).
