Zinc is an essential trace element for the human body. It activates a wide range of biochemical reactions responsible for the processes of growth and development of the body, wound healing, synthesis of hormones, reduction of inflammatory reactions, etc.
Zinc is especially needed for men. At puberty, a teenage boy is in dire need of this trace element, since zinc is responsible for the growth and production of the male sex hormone - testosterone . If the zinc level during this period is insufficient, then the boy lags behind in the sexual development of his peers.
Zinc, as a biological component, is present in many organs, but its maximum content is found in sperm (up to 2 mg of zinc per milliliter) and the prostate gland in men. This shows the great importance of zinc for spermatogenesis and the functioning of the prostate. In fact, in official medicine, zinc preparations are used for the treatment and prevention of male infertility and prostate diseases.
Daily zinc need for men
Most of the zinc (about 90%) is excreted along with food through the intestines, a small part is excreted with urine, and only 0.5-2% is excreted along with sweat. A significant part of the loss of microelement occurs during ejaculation. A man loses up to several milligrams of zinc during ejaculation, which, with frequent sexual intercourse, may result in its deficiency. For men who are sexually active, there is an urgent need for additional replenishment of this trace element. To do this, it is necessary to include in the diet foods rich in zinc (see Fig. 1), or at least not allow excessive removal of zinc from the body. Many aphrodisiacs , known as sexual desire products, have a high zinc content.
There are data showing that people who are actively involved in sports need this trace element more than people with low physical activity. Depending on the intensity of physical exertion, athletes should increase the recommended daily dose of zinc.
Zinc deficiency threatens for men:
- violation of sexual function;
- lower sperm quality and infertility;
- a decrease in the synthesis of sex hormones (testosterone);
- deterioration of general immunity, resistance to catarrhal and infectious diseases;
- slow healing of wounds;
- and etc.
What causes zinc deficiency?
- Food. The only adequate source of trace elements that allows you to replenish daily reserves, is plant and animal food. The massive depletion of soil, artificial animal feed, refined products contribute to the deficit of trace elements. Aggressive culinary processing, preservation and other methods of processing products significantly reduce the content of trace elements in them. For example, data from P. Bergner’s book The Healing Power of Minerals indicates that there is 43% less zinc in canned green peas than in fresh peas.
- Zinc antagonists. The decrease in zinc content in the body may be due to excessive accumulation of functional zinc antagonists: radioactive isotopes, copper, lead, cadmium.
- Alcohol. Low zinc content in the tissues and serum of individuals suffering from chronic alcoholism was revealed. The mechanism of inhibition of zinc in alcohol use is not completely clear, but presumably this is associated with an increase in the content of elements that are zinc antagonists and a deterioration in the absorbability of the trace element in the gastrointestinal tract when alcohol is taken. The use of zinc preparations for the relief of the effects of acute and chronic alcohol intoxication, as well as, possibly, the prevention of alcoholism, is shown.
Products containing zinc
The undisputed champion in zinc content is oysters. Literally, one and two mollusks will be enough to fill the organism's daily need for zinc. However, this menu is not available to everyone. The most affordable products are pumpkin and sunflower seeds, sesame, meat, nuts, cereals.
Approximate content per 100 g of product:

Zinc and Testosterone
(excerpt from the book Testosterone Factor, Shafiq Kaadri, 2007).
Zinc is not given due attention. North American eating habits and lifestyle lead to a partial zinc deficiency.
Alcohol, physical stress and aging reduce the intake of zinc in the body. In addition, the treated packaged products do not contain any zinc.
Zinc is an important trace element like iron. It is necessary for the production of testosterone. Zinc is involved in at least 500 different biochemical reactions in the body and therefore has a wide spectrum of action.
Many zinc functions. In the fat of the abdominal cavity in men lives a chemical thief - aromatase enzyme. These molecules steal testosterone circulating in the blood and turn it into the female hormone estrogen . Zinc reduces the amount of this enzyme and the efficiency of theft, thus helping more testosterone circulate freely in the bloodstream.
Ultimately, teams to increase or decrease testosterone synthesis come from the brain in real time. It is characteristic that the main hormonal controller, the pituitary gland, is located behind the eyes. Zinc increases the effectiveness of signals from the pituitary gland to the testicles.
For the billions of testosterone molecules produced every second, it is vital that the DNA from which testosterone is copied remains clean, free from breaks and write errors. Zinc helps keep this high-performance typewriter in working condition, restoring damage to the genetic matrix.
Finally, by improving the testosterone effect and the internal state of the testicles, zinc helps increase sperm count and makes sperm cells more energetic. Doctors call this increased mobility. Mostly zinc helps turn sperm into the best long-distance swimmers.
Take 50 mg of zinc daily. Zinc is especially recommended for men who regularly consume alcohol, lead a very active life, are obese or have problems with childbirth.
