Testosterone is a hormone that plays many roles in a man’s life. Maintaining high hormone levels to maintain good mental health and an active libido is essential. Testosterone and mental health are closely connected. Low testosterone levels can slow down the speed at which a man builds muscle mass and cause weight gain, possibly leading to depression or anxiety.

What is testosterone?

Testosterone is the hormone that distinguishes between males and females. From the first few days inside the mother’s womb, testosterone will cause a fetus to develop as a boy rather than a girl. (Females are the default form in humans and most animals. Unless testosterone is present in the blood, a fetus will develop into a female, and only if testosterone is there and in the right quantity can a male develop normally). After birth, it drives the body’s shape, form, and character. As a boy enters puberty, testosterone levels increase dramatically, bringing about the descent of the testicles, sperm production, pubic and facial hair, and a deeper voice. It’s also one of the chemicals that creates sexual desire and prowess.

Once the decade of maturation from boy to man has passed, the testosterone levels normally settle for about twenty years. After age 40, testosterone levels decline by roughly 1% each year. While this is an expected part of aging, it can cause some undesirable effects in how it can leave men feeling less energetic and focused and with lower levels of sexual desire (libido) and performance. 

Some diseases and certain medications can influence testosterone levels, such as testicular cancer, radiation treatments, and thyroid diseases.

The symptoms of low testosterone

The most common symptoms of low testosterone include:


Testosterone and mental health

Some studies have shown that men with lower levels of testosterone (low T) are more likely to suffer from depression. The connection between low T and low libido or depression is well established, but it’s not yet proven whether low testosterone levels can cause depression or vice versa.

What’s more relevant than knowing whether low T can cause depression is that multiple scientific studies have shown that treating men who have low hormone levels and complain of symptoms like mood swings, anxiety and depression with testosterone boosters has definite benefits. One analysis of multiple studies of the use of Testosterone Replacement Therapy in the treatment of depression, published by the National Institute of Biotechnology Information, found a significant reduction of depressive symptoms after treatment with testosterone. The study found that the benefit was proportional to the dose – the more testosterone, the greater the benefit.

Not everyone will get the same benefit from testosterone therapy. It is important to get testosterone levels checked and analyzed by a doctor before undergoing hormone replacement therapy. It will also largely depend on your age, medical history, and the medications you are taking for other conditions.
