What are the signs of a low testosterone ?

Testosterone is usually referred to as a male sex hormone though females also produce it in their ovaries. But in men, this hormone is mainly produced in the testes although small amounts are also produced by the adrenal glands.

Testosterone in men is responsible for a man’s appearance and sex drive (libido). Besides, it promotes sperm production in the testes. It also leads to the building of muscles and an increase in bone mass. However, this important hormone can decrease, especially with age.

According to the American Urology Association, 2 out of 10 men over the age of 60 years have low testosterone levels. And the situation gets worse with age since 3 out of 10 men over the age of 70 years have a low testosterone level. In this post, we’re going to look at the signs that show you might have a low testosterone level. So, be sure to read on for more information.

What signs will show that you have low testosterone?

Testosterone deficiency (TD) can manifest itself in the following symptoms:

Reduced sex drive

Testosterone affects a man’s libido or sex drive. Since testosterone levels might drop with age, some elderly men might experience a low sex drive as they age. If your sex drive has reduced, there is a good chance that you have testosterone deficiency.

Difficulty achieving an erection

Testosterone not only increases your sex drive but also improves your chances of achieving and maintaining an erection. It helps you achieve and maintain an erection by stimulating the receptors in your brain to produce nitric oxide.

Nitric oxide then initiates a series of chemical reactions in the brain necessary for an erection. If you have a testosterone deficiency, your brain receptors will not produce enough nitric oxide for an erection. In other words, you will might experience erectile dysfunctions if you have low testosterone levels.

Loss of the body hair

Men owe their phenotypic characteristics such as beards and hair on the body to testosterone. This is to say that testosterone promotes the production of facial and body hair. Even though balding is a natural part of aging for men, some people experience hair loss from their faces and body due to testosterone deficiency.

Low sperm count

More testosterone is produced in a man’s testes. This hormone, therefore, promotes the production of sperms and semen in the testes. A man with high testosterone levels will experience a higher sperm count. But a man with testosterone deficiency will experience low semen and sperm production.

Depressions, irritability, and difficulty concentrating

One research found that there is a strong relationship between testosterone and a man’s psychology. The research found that men having low T are prone to depressions, irritation, and can have a hard time concentrating on something. As such, low T can affect a man’s mood and mental state.


Fatigue could also be a sign of low T. First, testosterone is responsible for muscle mass in men. If you have a testosterone deficiency, it means you will have less muscle mass than a normal person and this could lead to fatigue.

Decreased bone mass

Osteoporosis is a condition that affects mostly women. This condition causes the bone mass to reduce. However, it can also affect men. Testosterone is a hormone that performs many functions in the body, among them, the production and strengthening of the bones.

If the testosterone levels drop below normal, a person will have decreased bone mass. As a result, you may experience such symptoms as a weak grip and receding gums.

Low blood counts

Anemia results when you have low blood counts. And having low T increases the risk of developing anemia, according to research by the Journal of the American Medical Association.

Being overweight (Obesity)

Testosterone deficiency can also cause obesity in men. Men with low T might develop a condition known as gynecomastia that can lead to enlarged breasts. If there is an imbalance between testosterone and estrogen in men, obesity might arise. As such, lower testosterone levels in men can cause obesity or overweight.

Reduced testes size

Testosterone hormones play a crucial role in shaping a ma’s sex life. These hormones are mainly found in the testes as we have already seen. Besides regulating the production of the sperms and semen, they also influence the development of the testes. Lower testosterone levels cause shrunken testes in men. So, if you have this problem, there is a good chance that you have a low testosterone level.


Testosterone is a hormone that shapes a man’s looks and sex life. Also, it influences a man’s psychology. As such, it should be sufficiently available within a man’s system. However, some men might have a testosterone deficiency, which can have adverse effects on their lives.

But you can always know if you have low T if you show any of the signs we have mentioned and explained here. In case you have any of the symptoms here, consult a doctor for help.
