Why Testosterone Declines In Aging Men

Testosterone levels less than 300ng/100ml are below normal. Low testosterone causes poor sexual function, mental decline, increased body fat and decreased muscle mass. Other symptoms include low sperm count, anemia, bone loss and abdominal obesity. It’s linked to coronary artery disease, diabetes and premature death.


Genetics, sexual organ abnormalities, infections, tumors, injury and poor metabolic health are the main causes for decreased testosterone levels with age. Regular exercise, healthy diet and adequate sleep are the most important things you can do to promote metabolic health and maintain normal testosterone levels with age. Healthy lifestyle is more effective than drugs such as Viagra for maintaining sexual potency. (International Journal Impotence Research, 18: 223-228, 2006)
