What Is Testosterone Deficiency

Low testosterone... how does it happen? In most men, testosterone production is automatic and effortless. Testosterone is produced by the testes in response to signals sent out by the hypothalmus and the pituitary gland (located at the base of the brain). However, in some men, the testes may be unable to fulfill the body’s testosterone needs. This condition, called hypogonadism, can result from a variety of causes. Among the causes are chromosomal abnormalities, side effects from certain medications, pre-existing conditions such as diabetes, or injury to the testes.

Whatever the cause, low testosterone levels can result in decreased sexual function, decreased sexual desire, diminished energy, and depressed mood.
