What Is Testosterone?

Testosterone is a hormone that is made by the testicles and the ovaries. It’s an important hormone for the body as it helps to keep muscles, bones, and organs healthy. Testosterone can also be found in women’s bodies too. Women have much lower levels of testosterone than men do but it still plays a role in their health. Testosterone has many roles in the body.

What is testosterone?

As an illustration of what a small amount of testosterone looks like, here are some examples:

  • Testosterone is involved in your sex drive.
  • Testosterone makes hair follicles grow. It’s not only hair on your head but also your eyebrows, eyelashes, and even your pubic hair. What is the difference between testosterone and estrogen? Testosterone and estrogen are both hormones but they do different things. Both are made by glands but testosterone is made by the testicles and estrogen is made by the ovaries. Men and women have both types of hormones but they have different levels in their bodies. Here are some examples:
  • Testosterone is an androgen hormone that is produced in men’s testicles.
  • The amount of testosterone in a man’s body is about 8-10 times more than the amount of estrogen.
  • Testosterone can cause a man to grow taller because it can make bone and muscle cells grow faster than other cells. In women, it can cause menstrual cycles to start and cause breasts to grow bigger.
  • Testosterone is involved in sperm production.
  • Testosterone is also involved in a man’s sexual interest. It’s also what causes a man’s sex drive to increase. Testosterone has an effect on the penis and testicles as well.

Types of testosterone

Testosterone is part of a group of hormones called androgens. Androgens are the hormones responsible for the development of secondary sex characteristics such as facial hair, hair on the arms and chest, muscles, and voice changes. Testosterone is the primary androgen that is produced by the testicles. Other androgens include Dihydrotestosterone (DHT), which can be made in other parts of the body but only in much smaller amounts. Estrogen is also made in small quantities in many different parts of the body. Testosterone is the most important hormone for men because it helps with their sex drive. It makes them want to have sex, and it keeps them from having erectile dysfunction or impotence.

Causes of low testosterone level

There are many reasons why a man may have a low level of testosterone. They are:

  • Aging The testicles start to decrease in size as a man gets older. The reason is that testosterone is made by the testicles. As the testicles get smaller, less testosterone is produced. The aging testicles may produce a lower amount of testosterone than they did when the man was younger.
  • Cancer treatment If a man has been treated for cancer, he may have low levels of testosterone. This is because some medicines used in chemotherapy can damage the testicles and affect how well they make testosterone.
  • Hormonal disorders Some hormonal disorders can cause low levels of testosterone. Hypogonadism (a medical term for low testosterone) is a condition that causes low testosterone levels.

How to increase testosterone levels

There are many ways to raise testosterone levels.

They include:

Taking anabolic steroids: This is not recommended. Taking anabolic steroids can cause many health problems and it can lead to heart disease. It is important to avoid using anabolic steroids if you have any heart problems or high blood pressure.

Exercising: Regular exercise is good for your health, including your testosterone levels. Exercise increases testosterone in men. It also helps with weight loss.

Supplements and diet: There are many supplements that you can take that can help increase testosterone levels. One is 5-alpha-reductase inhibitors which is found in plants. This is known to increase testosterone levels.

Another is Tribulus Terrestris. It’s a plant that contains biochanin A and flavonoids. These compounds may increase testosterone levels.

Other supplements: Vitamin D is also thought to increase testosterone levels in men. It is thought to be involved with the conversion of testosterone to DHT.

What can cause a decrease in testosterone level

There are two things that can cause a decrease in testosterone levels:

Older age: Men start having lower levels of testosterone as they get older.

Diseases or other conditions: Some diseases or other conditions can cause low testosterone levels. Hypogonadism is when a man has too little testosterone. Hypogonadism may happen for many reasons. The most common cause of this is a problem with the pituitary gland.


Testosterone is a hormone that makes a man want to have sex, and it helps keep men from having erectile dysfunction or impotence. Testosterone levels in men decrease with aging and certain medical conditions, including heart problems. 

Testosterone is also used as an anabolic steroid by some athletes. Testosterone can be measured in the blood or urine, or it can be determined through a simple blood test called the testosterone level. Blood testing is not very accurate because there is no perfect way to get a precise measure of testosterone in the blood.
