Causes

Although the causes of compulsive sexual behavior are unclear, they may include:

• An imbalance of natural brain chemicals. Certain chemicals in your brain (neurotransmitters) such as serotonin, dopamine and norepinephrine help regulate your mood. High levels may be related to compulsive sexual behavior.
• Changes in brain pathways. Compulsive sexual behavior may be an addiction that, over time, might cause changes in the brain's neural circuits, especially in the reinforcement centers of the brain. Like other addictions, more-intensive sexual content and stimulation are typically required over time in order to gain satisfaction or relief.
• Conditions that affect the brain. Certain diseases or health problems, such as epilepsy and dementia, may cause damage to parts of the brain that affect sexual behavior. In addition, treatment of Parkinson's disease with some dopamine agonist medications may cause compulsive sexual behavior.
