Is 'sex addiction' a disorder? Psychiatry's two big manuals disagree
The American Psychiatric Association rejected sexual addiction as a diagnosis in 2010 and still does not list it. The World Health Organization went the other way in 2018, adding compulsive sexual behaviour disorder to its classification. Hypersexuality sits in that gap, possibly affecting 2 to 6 percent of people, depending on who defines it.
Hypersexuality describes sexual urges or activity intense enough to cause distress or disrupt daily life. Older labels split it by sex, nymphomania for women and satyriasis for men, and the WHO's ICD-10 kept those words under 'excessive sexual drive'. Researchers have since used a dozen rival names, from sexual compulsivity to hypersexual disorder, often reflecting whether they see it as an addiction, an impulse-control problem or a relative of obsessive-compulsive disorder.
Scepticism runs deep. In 1988 Levine and Troiden argued that calling urges 'extreme' simply stigmatises people who break their culture's norms, and some authors still say the label reflects disapproval rather than illness. Because there is no agreed definition or measuring tool, prevalence figures swing widely, with higher estimates among men and people who have experienced trauma. The ICD-11 category introduced in 2018 frames the core problem as a persistent failure to control intense, repetitive sexual impulses.
Often the behaviour is a symptom of something else. Mania in bipolar disorder can send sex drive soaring, and borderline personality disorder commonly involves impulsive sexuality. Damage to the frontal or temporal lobes, from strokes, injuries or diseases such as Pick's, can remove inhibitions, and sexually inappropriate behaviour appears in 7 to 8 percent of Alzheimer's patients. Medication matters too: dopamine agonists used for Parkinson's disease can trigger it, reflecting overactivity in the brain's mesolimbic reward pathway. Studies also link it with ADHD, another condition tied to dopamine.
The consequences reported in studies can be serious. In one set of figures, 27.5 percent of affected people had caught a sexually transmitted infection through their behaviour, and 22.8 percent had lost a relationship because of it. Other addictions, including gambling, compulsive spending and substance dependence, frequently occur alongside. Because patients vary so much, clinicians rely on a broad interview covering sexual, psychiatric, medical and substance histories, plus questionnaires such as the Sexual Addiction Screening Test.
