Testosterone (tess-TOSS-tuh-roan), the primary male hormone, is
produced in the testes (TESS-teez), and governs many functions
throughout your body. It's necessary for sex drive in both males and
females, though women have much smaller amounts. In men,
testosterone is responsible for normal development of sex organs, the
production of sperm, and male characteristics like facial hair and a deep
voice. Testosterone also affects bone and muscle growth, the prostate,
and your central nervous system. Levels tend to peak early in the
morning, and fall to their lowest point in late evening. As you age,
testosterone production gradually declines. By age 60, some men's
levels become so low as to cause fatigue, lack of sex drive, and the
inability to get or maintain an erection. Irritability, decreased muscle
mass, reduction in facial hair, and increased breast size are other possible
symptoms. Some younger men may also experience an abnormal drop
in testosterone, a condition known as hypogonadism
(hy-poe-GOE-nad-izm). In either case, hormone replacement therapy
may be needed. The most recent method of supplementing testosterone
levels is with a one-dose patch or topical cream. For more information on testosterone, consult a healthcare
professional.
