Testosterone is the main sex hormone that men have. It controls male physical features. The testes (testicles) make testosterone.
Women have testosterone too, but in much smaller amounts than in men.
Testosterone helps bring on the physical changes that turn a boy into a man. This time of life is called puberty. Changes include
Men also need normal amounts of this hormone to make sperm and be able to have children.
The brain and pituitary gland, a small gland at the base of the brain (see image below), control production of testosterone by the testes. From there, testosterone moves through your blood to do its work.
Your testosterone levels change from hour to hour. They tend to be highest in the morning and lowest at night.
Testosterone levels are highest by age 20 to 30 and slowly go down after age 30 to 35.
For many reasons, testosterone can becomeand staytoo low. Less often, testosterone levels can become too high. When this hormone is not in balance, health problems can result. Ask your doctor if you should get your testosterone level checked if you have any of the problems mentioned below. You can get treatment to fix hormone problems.
Early symptoms (changes you feel) and signs (abnormalities that your doctor finds) of low testosterone in men include
Later, low testosterone can lead to decreased muscle and bone strength, less energy, and lower fertility.
Some things can temporarily lower testosterone, for instance, too much exercise, poor nutrition, or serious illness. Living a healthy lifestyle with regular exercise and a good diet helps maintain normal testosterone levels.
When young boys have too much testosterone, they can start puberty too early (before age 9). Some rare conditions, such as certain types of tumors, cause boys to make testosterone earlier than normal.
Young boys also can have too much testosterone if they touch testosterone gel that an adult man is using for treatment
To measure your testosterone level, your doctor can order a blood test. The test should be done in the morning between 7:00 and 10:00. If the result is not normal, you should repeat the test to make sure of the result. In healthy men, testosterone levels can change a lot from day to day, so a second test could be normal.
