Testosterone Replacement Therapy

Signs and Symptoms

Of Low Testosterone



Testosterone levels generally peak during adolescence and early adulthood. As you age, your testosterone level gradually declines — typically about 1% a year after age 30 or 40. For older men, it's important to determine if a low testosterone level is due to normal aging or if it is due to a disease (hypogonadism).

• Changes in sexual function. This might include reduced sexual desire, fewer spontaneous erections — such as during sleep — and infertility.
• Physical changes. Various physical changes are possible, including increased body fat, reduced muscle bulk and strength, and decreased bone density. Swollen or tender breasts (gynecomastia) and body hair loss are possible. You might have less energy than you used to.
• Emotional changes. Low testosterone can contribute to a decrease in motivation or self-confidence. You might feel sad or depressed, or have trouble concentrating or remembering things.
