Low TesTOSTERONE SYMPTOMS

As men age, testosterone levels drop very gradually, about 1% to 2% each year — unlike the relatively rapid drop in estrogen that causes menopause in women. More than a third of men over age 40 may have lower levels of testosterone than what might be considered "normal".

Symptoms of testosterone deficiency in adult men include:

• Loss of muscle mass, increased abdominal fat
• Low motivation, foggy brain, poor concentration and depression
• Low libido, impotence, reduced sperm count and infertility
• Reduced body and facial hair
• Increased breast size (gynoclomastia)
• Hot flashes
• Loss of body hair
• Brittle bones and an increased risk of fracture

Some men who have a testosterone deficiency have symptoms or conditions related to their low testosterone that will improve when they take testosterone replacement. For example, a man with osteoporosis and low testosterone can increase bone strength and reduce his fracture risk with testosterone replacement.
