Spermatogenesis = sperm cell development
Spermatogenesis or sperm cell development begins during the embryonic stage of the unborn child. The process involves various interactions between sex cells and the body cells. This development begins with spermatogonia (germ cells). Starting at puberty, the spermatogonia begin to divide under the influence of male hormones. Indispensable within this development are sertoli cells, special cells with a nourishing and supportive function.
Spermatids
Spermatids are sperm cells that have yet to differentiate into a mature sperm cell (spermatozoa). Spermatozoa (plural spermatozoa) consist of a head, neck, middle and whip tail. The head of the spermatozoon contains enzymes that are needed for entry into the egg cell. The midpiece must provide much energy for the movements of the whip tail and contains many mitochondria.
Testis
Sperm cells are made in the testis (testicles). This process is called spermatogenesis. The optimal temperature for sperm production is a few degrees lower than the body's core temperature, which is why the testes hang slightly off the body.
Man produces about 50,000 sperm cells per minute from puberty onward. The whole process from spermatogonia to spermatozoa takes about 65 to 75 days.
Sperm quality
In recent years, the sperm quality of European men (as well as elsewhere in the world) has declined significantly. The exact cause is not yet known an unhealthy lifestyle, stress and the large amount of hormone disruptors and other toxins in our environment are obvious candidates.
Testosterone
Testosterone is an important male hormone involved in healthy libido, fertility and sexual function. It stimulates the formation of sperm cells and also promotes protein production in the body.
Important nutrients
Zinc has a beneficial effect on testosterone levels in the blood. For good sperm quality and fertility, Zinc and Selenium are important minerals. These minerals also help protect the body from oxidative damage.
