The male sex hormone, testosterone, has a major impact on male health and performance. We've gathered everything you need to know about testosterone right here!
Testosterone is commonly known as the male sex hormone, but it is present in both men and women. In men, it is produced in the testicles, while in women, it is produced in the ovaries, but in much smaller amounts.
Often linked to sex drive, testosterone also plays a crucial role in sperm production. Numerous studies indicate that it influences bone density and muscle mass, as well as fat distribution in men. Additionally, a man's testosterone levels can impact his mood.
This hormone is also vital for the production of red blood cells, which transport oxygen to all parts of the body.
Testosterone is the most important sex hormone in men. It is essential for:
As men age, testosterone levels decrease. In fact, a 20-year-old man produces on average 60% more than a 50-year-old man!

Testosterone deficiency is a common issue, especially as men get older. This topic has received a lot of media attention, highlighting the importance of understanding that testosterone deficiency often becomes more prevalent with age.

Testosterone is primarily produced in the testes, though a certain amount is also produced in the adrenal cortex. Production takes place in the Leydig cells.
Leydig cells are hormone-producing cells in the testicles. Luteinising hormone (LH) stimulates the production and secretion of testosterone from these cells.
Testosterone is responsible for inhibiting the production of LH. In other words, once testosterone is produced, LH will not be produced.
Damage to the testicles can lead to reduced production of the hormone.
This male sex hormone plays a key role in the development of the genitals during puberty. Luteinising hormone (LH) is inhibited by testosterone at an early age, but when puberty begins, the interaction between these two and several other hormones becomes significant. It is therefore very important to maintain this balance throughout life in order to feel healthy.
On the surface of prostate cells, we find something called androgen receptors. These receive signals from testosterone.
Androgen receptors are crucial for developing a deeper voice, increased muscle mass, beard growth, pubic hair, and the development of the penis, prostate, and seminal vesicles. In adult men, they are also important for maintaining sexual desire and sexual ability.

A man of around 35 years old produces between 200 and 1200 nanograms of testosterone per decilitre.
However, this is very individual and will vary based on several different factors such as diet and stress. For example, production will increase after exercise as the body compensates for the loss of energy.
If your production is low, such as 50-80% of optimal testosterone production, it may be smart to make an effort to increase the level. You can do this by exercising or changing your diet.

Testosterone levels vary between individuals, but many experience their highest levels in their 20s. This remains fairly stable until around the age of 35, when, for many, the level slowly starts to decline.
Besides age, other factors such as exercise, diet, and testicular injuries also affect your testosterone levels.
Many men experience a kind of midlife crisis in their 50s, which can lead to a decrease in vitality and energy levels. To prevent such a crisis, it’s a good idea to exercise and switch to a diet rich in zinc, magnesium, and other nutrients that boost testosterone production.
First and foremost, it's important to exercise and ensure you eat a healthy and varied diet. Your diet should contain the necessary amounts of zinc, magnesium, and vitamin B6. Zinc is good for maintaining normal testosterone levels in the blood and supports normal reproductive function and fertility. Vitamin B6 helps reduce fatigue.
