WHAT is low testosterone?
Testosterone is a hormone produced by the human body. It’s mainly produced in men by the testicles. Testosterone affects a man’s appearance and sexual development. It stimulates sperm production as well as a man’s sex drive. It also helps build muscle and bone mass.
Testosterone production typically decreases with age. According to the American Urological Association, about 2 out of 10 men older than 60 years have low testosterone. That increases slightly to 3 out of 10 men in their 70s and 80s. Men can experience a range of symptoms if testosterone decreases more than it should. Low testosterone, or low T, is diagnosed when levels fall below 300 nanograms per deciliter (ng/dL).
A normal range is typically 300 to 1,000 ng/dL, according to the Food and Drug Administration. A blood test called a serum testosterone test is used to determine your level of circulating testosterone.
A range of symptoms can occur if testosterone production drastically drops below normal. Signs of low T are often subtle. Here are 12 signs of low T in men.
