What is SERTOLY CELL?
The Sertoli cell is a highly specialized cell found in the testes. It plays an important role in the development and maturation of sperm or sperm, during the testes, a process called spermatogenesis. Because SERTOLI cells work to a large extent to help developing sperm cells during their maturation process, it is sometimes referred to as a nurse. In addition to the excretion of many important hormones and other substances that cause proper development, the cell is also consumed by the cell of the excess material that remains after the development of the sperm. Another function of SERTOLI cell is to control the movement of hormones, nutrients and chemicals in the seed tubules. The cells of the cell are produced in this structure and differ the interior of the tubules. They are activated by the hormone stimulating follicles (FSH), which interacts with FSH-Receptors on the cells of cells. The complete process of spermatogenesis takes about 64 days in a human man. During the development of spermatozoa, the cell launches the cell several phases of growth by excretion of certain substances. For example, spermatogenesis begins when the cells sertoIf they exclude protein to increase testosterone concentration in seminate tubules.
puberty starts the beginning of spermatogenesis and the process continues throughout the life of a man. Total sperm production decreases with age, but it will never stop in a healthy individual. The number of sperm, their motility and the overall fertility of the individual is determined by the efficiency and proper functioning of spermatogenesis. During spermatogenesis, germ cells that are cells from which mature sperm eventually grow, they actually travel along the sertoli cell with the progress of their development.
One form of infertility specifically related to the cell Sertoli is only the syndrome of the sertoli-cells. In this state, seminar tubules contain only cells of cells, preventing the testicles from producing sperm. The condition is usually diagnosed when men who are worried about their fertility are tested, and it has been shown that they have no sperm in ejaculation. SonDrom only sertoli-whole is very rare and the cause is unknown.
cells of cells are not able to reproduce and after spermatogenesis begins in a teenage male, no other cells cells are produced by the body. However, techniques for cell growth in laboratory conditions have been developed. Some forms of human infertility may be treatable by these cells.
