ICD-11 and Compulsive Sexual Behavior Disorder
How the ICD-11 defines compulsive sexual behavior disorder (CSBD), the diagnostic criteria, why the classification matters, and how it compares to sex addiction.

The ICD-11, the World Health Organization’s international classification of diseases, formally recognises compulsive sexual behavior disorder (CSBD) and classifies it as an impulse-control disorder. This was a landmark, giving what people often call “sex addiction” official recognition. The ICD-11 criteria describe a persistent pattern of failure to control intense, repetitive sexual impulses or urges, resulting in repetitive sexual behavior over an extended period (such as six months or more), that causes marked distress or significant impairment in personal, family, social, or other areas of life. Importantly, distress based purely on moral judgement is not sufficient for the diagnosis. The ICD-11’s inclusion of CSBD supports clinical recognition and treatment of the condition worldwide.
What the ICD-11 is
The ICD-11 is the eleventh revision of the International Classification of Diseases, the World Health Organization’s global system for classifying health conditions. It is used internationally for diagnosis, health data, and healthcare planning. Its inclusion of compulsive sexual behavior disorder (CSBD) matters because it gives formal, international recognition to a condition that many people refer to as sex addiction.
How CSBD is classified
In the ICD-11, compulsive sexual behavior disorder is classified as an impulse-control disorder, rather than as an addiction or a paraphilia. This placement reflects the current scientific understanding: the core problem is a persistent failure to control intense sexual impulses, which is characteristic of impulse-control disorders. The classification shapes how clinicians understand and approach the condition.
| Element | ICD-11 detail |
|---|---|
| Name | Compulsive sexual behavior disorder (CSBD) |
| Category | Impulse-control disorder |
| Core feature | Failure to control repetitive sexual urges |
| Duration | Persistent pattern over an extended period |
| Requirement | Marked distress or significant impairment |
The diagnostic criteria
The ICD-11 criteria describe a persistent pattern of failure to control intense, repetitive sexual impulses or urges, leading to repetitive sexual behavior over an extended period, often understood as around six months or more. The behavior must cause marked distress or significant impairment in personal, family, social, educational, occupational, or other important areas of life. Crucially, the criteria specify that distress arising solely from moral disapproval of one’s sexual behavior is not enough to meet the diagnosis, a safeguard against pathologising normal behavior.
Why the classification matters
The ICD-11’s recognition of CSBD is significant for several reasons. It validates the experience of people who struggle with compulsive sexual behavior, supports clinicians in diagnosing and treating it, guides research, and provides a shared international framework. Because the ICD is used worldwide, its inclusion of CSBD helps ensure the condition is taken seriously and that affected people can access appropriate treatment.
ICD-11 versus “sex addiction”
“Sex addiction” is a common, informal term; compulsive sexual behavior disorder is the formal ICD-11 diagnosis for much the same pattern. The ICD-11 deliberately frames it as an impulse-control disorder rather than an addiction, reflecting scientific debate about the best model. It also contrasts with the DSM-5, which does not include the condition. For most people seeking help, the practical result is the same: a recognised condition that can be assessed and treated.
The bottom line
The ICD-11 formally recognises compulsive sexual behavior disorder as an impulse-control disorder, defined by a persistent failure to control intense sexual urges leading to repetitive behavior that causes marked distress or impairment, with moral disapproval alone explicitly excluded. This international recognition supports the diagnosis and treatment of what many call sex addiction, worldwide.
