Sex drive (libido) varies greatly among men. Different men find different degrees of libido satisfactory. Libido may be decreased temporarily by conditions such as fatigue or anxiety. Libido also tends to gradually decrease as a man ages. Persistent low libido may cause a man and his sex partner distress.

Occasionally, libido can be low throughout a man's life. Lifelong low libido can result from traumatic childhood sexual experiences or from learned suppression of sexual thoughts. Most often, however, low libido develops after years of normal sexual desire. Psychological factors, such as depression, anxiety, and relationship problems, are often the cause. Some drugs (such as those used to treat high blood pressure, depression, or anxiety) and decreased levels of testosterone can also lower libido.

A blood test can measure the level of testosterone in the blood. However, the diagnosis is usually based on the man's description of his symptoms.

If the cause is psychological, various psychological therapies—including behavioral therapies, such as the sensate focus technique can help. If the testosterone level is low, testosterone can be given, usually as a patch or gel applied to the skin or as an injection.

If a medication being taken appears to be the cause, the doctor can often try treating the man with a different drug.
