Spermatogenesis is the process that takes place in the testicles for creation of sperm. Sperm, meanwhile, are the male gametes: that is, the sex cells that have the function of fertilizing the ovum.
Spermatogenesis is the gametogenesis of man. Through the meiosis and the mitosis, the germ cells called spermatogonia allow the production of sperm in the gonads (the testicles). These gametes then mature in the epididymis.
Spermatogonia are found in the epithelium of the seminiferous tubules, coiled ducts found inside the testicles. Thanks to the gonadotropin-releasing hormone (GnRH), spermatogenesis is activated, which lasts between sixty-two and seventy-five days in the case of Humans.
Developed in three phases, spermatogenesis generates sperm, which are haploid cells with a flagellum (tail) that allows them to move and a head that houses the material of the chromosomes. When a sperm is ejaculated and manages to join an ovum (the female gamete), the fertilization.
It should be noted that sperm and various fluid substances form the semen. With the ejaculation, this liquid is expelled by the men by means of the urethra. Thus, when a man and a woman maintain a sexual relationship through the vagina, fertilization is possible.
It is important to mention that various disorders prevent spermatogenesis. Hormonal problems, infections, chromosomal alterations and trauma, for example, can suppress sperm production.
One of the most common is exposing the testicles to excessively high temperatures. It has been scientifically proven that by increasing the heat in that zone sperm production is reduced. Outside of the medical field, this is also often commented on among men who enjoy cooking, as they are often kept in front of the oven or stove for too long periods, and this is not beneficial.
