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.
  • Conditions that affect the brain. Certain diseases or health problems may cause damage to parts of the brain that affect sexual behavior. Epilepsy, Huntington's disease and dementia have all been associated with compulsive sexual behavior. In addition, treatment of Parkinson's disease with some dopamine agonist medications may cause 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 — the network of nerves that allows brain cells to communicate with one another. These changes may cause pleasant reactions by engaging in sexual behavior and unpleasant reactions when the behavior is stopped.
