What is testosterone?
Testosterone is a hormone. It’s made by the bodies of both men and women. It plays a role in puberty and fertility. It also affects sexual desire. In men, most testosterone is made in the testes. In women, most testosterone is made in the ovaries.
Men have higher levels of testosterone than women. It’s thought that testosterone greatly influences the development of many characteristics considered to be male traits. It helps increase muscle bulk, bone mass, physical strength, and the amount of body hair.
How to increase testosterone levels?
There may be certain lifestyle changes to help increase testosterone levels. Adding resistance exercise and losing weight are two changes that can have an effect.
Research has indicated that resistance exercise, such as lifting weights, is related to temporary increases in testosterone levels. However, those increases are typically much higher in younger men than older men and don’t appear to greatly increase the overall level of testosterone.
Some types of herbal supplements claim to be “testosterone boosters.” The makers of these products claim that the ingredients help to increase levels of testosterone. However, there isn’t enough research to support their effectiveness. Additionally, these products are not closely regulated by the U.S. Food and Drug Administration. You may find there are more natural steps that may help to boost your testosterone level.
Testosterone injections are one of the more common forms of testosterone replacement therapy. They are typically given by a doctor. You need them less frequently than other forms.
Testosterone side effects
If you have testosterone replacement therapy, you will need frequent blood tests to check your testosterone levels and to check for side effects. Side effects can include an increased number of red blood cells and rarely, blood clots. You also may experience acne and breast enlargement.
Low testosterone in men
Testosterone levels in men usually peak around the age of 19 years. After the age of 30 years, these levels begin to naturally decrease in all men. However, for some men these levels become abnormally low. According to one study Trusted Source, almost 40% of men older than 45 years have abnormally low levels of testosterone. These abnormally low levels can cause symptoms.
