Spermogenesis is the process of sperm formation in the male gonads - the testes. Sperm are needed to fertilize an egg and create new life.
Spermatogenesis begins in the embryonic period of development, when male germ cells are formed during the process of meiosis. They then go through several developmental stages to reach maturity and become sperm.
The first stage of spermatogenesis is the growth and division of cells called spermatids. At this stage, chromosomes are doubled and two spermatids are formed. The spermatids then continue to divide, forming first-order spermatocytes.
The second stage of spermatogenesis is called meiosis. During meiosis, the number of chromosomes is reduced from 23 to 23. This is necessary so that the first-order spermatocyte can merge with the egg and form a zygote. After meiosis, the spermatocyte becomes a second-order spermatid.
The third stage of spermatogenesis is the growth and maturation of second-order spermatids. At this stage, the cells increase in size and take the form of third-order spermatocytes. Then another round of meiosis occurs, which leads to the formation of sperm.
Finally, the sperm leave the testicles and enter the epididymis, where they are stored until ejaculation. During ejaculation, sperm enter the woman's vagina and can fertilize the egg.
The process of spermatogenesis takes about 74 days in men, and this process can be disrupted by various diseases such as testicular inflammation or genetic abnormalities. Therefore, it is important to monitor your health and consult a doctor if necessary.
Spermatogenesis (spermatogenesis) is the process of generating male germ cells in a man's body. The process occurs in the seminiferous tubules, through which mature sperm mature after their production. It ensures reproduction in humans and other primates. Sperm formation occurs as early as 26 weeks of intrauterine development of the male fetus under the guidance of the actively working pituitary gland located in front and close to the center of the seminiferous tubule. Gonadotropic hormones secreted by the pituitary gland, including luteinizing hormone (LH), stimulate the production of lutein (male sex hormone) in Sertoli cells. The latter stimulates not only spermatogenesis, but also the development of the female genital organs. Once the production of sperm in the tubule is complete, the tubule closes to prevent the release of unfertilized sperm. The outside of the tubule is covered with a layer of Sertoli cells. Cells of the myotonic layer surrounding the seminiferous tubules. Their function is to synthesize aroma carrier proteins necessary for the development and maturation of sperm. Consequently, the spermatogenic epithelium of the seminiferous tubules consists of two layers: the outer spermatogenic epithelium, represented only by spermatids, and the inner “glomerular” layer, formed by cells of the myotonic type. The wall of the tubules is lined with a layer of specific cells that form Sertoli tissue. These cells secrete lipids that help maintain the concentration of testosterone in the tubular environment.
