The treatment plan depends to a large extent on the exact cause of the sexual problem. If the cause is psychological, the help of a psychiatrist or psychologist may be helpful. Often in this situation, cognitive-behavioral therapy is the treatment used. Sometimes the treatment will include couples therapy. If the cause of decreased libido is medication taken, there are sometimes alternative medications without sexual side effects. For others, hormone replacement may be suggested. Talk to your doctor about any changes in libido you have experienced.
