5 facts about testosterone

Testosterone is often associated with stereotypically male traits like impulsiveness, competitiveness and a high sex drive. However, this hormone is a lot more complex than you think. Here are five interesting facts about it.

1. Peak levels. Testosterone levels peak at around 30 years of age. After that, they drop off steadily at a rate of about one percent a year.

2. Not just a male hormone. Women also produce testosterone. However, they do so at a rate of six to 10 times less than men.

3. Anabolic steroid. Testosterone is often used in supplement form by athletes looking to increase their muscle mass quickly. These supplements come with a number of serious side effects, many of which are life threatening.

4. Role in fetal development. Fetuses developing into baby boys will begin producing testosterone during the seventh week of pregnancy, around the time the testicles begin to form. Before this, there’s no difference between a male and female fetus.

5. Production. Testosterone is chiefly produced by the testicles, with the adrenal glands also producing a small amount. Hormone production itself is regulated by two glands located at the base of the brain: the hypothalamus and the pituitary.

Worries about low testosterone levels are common, especially as men get older. However, keep in mind that it’s a complex hormone that performs multiple functions within the human body. Many conditions can affect your testosterone levels, so always consult a doctor if you have concerns and steer clear of herbal remedies and fad diets that purport to boost its production.
