What is spermatide?

Spermatide is the middle phase of sperm growth in a human man. Each spermatide contains 23 chromosomes. This means that each of them is a "male" half of a cell or gamete that contains half of the genetic material needed to create a human being. The second half of genetic information will be provided with a female egg. However, before they are able to fertilize eggs, spermatide will have to undergo the maturation process.

To fully understand what spermatide is, it is necessary to know the basics of sperm production and where the spermatid stage fits into the whole. The name "spermatide" is very similar to names given by many other stages of cell development. Sperm production begins with puberty in human testicles - these genital organs hang without the body to maintain the optimum temperature for sperm production. Inside the testes are seminar tubules that are lined with sertoli cells and contain spermatogonia or "child" sperm. Each nichbuňky contains 46 chromosomes and via mitosis with spermatogonia then divided into sets of fourspermatides. During the time of their ripening, the sources of cytoplasms are connected. This period of sperm formation includes spermatides incorporating random pieces of superior DNA in order to create variations that provide general information that each sperm carries is unique.

The process of mitosis, which divides spermatogonia into spermatides, is long and lasts up to three weeks. The process is put into motion of several hormones, the best known of which is testosterone. At the end of his ripening process, spermatids turn into familiar spermatozoa, which is what many people think when they hear the word "sperm". "

Although they have a head and tail, spermatozoa will not be fully mature yet. They will be moved to the epididymis tube, where they basically learn to swim and gather strength to penetrate the female egg. After two weeks, they are finally stored in DEFEREND supplies, where they will be mixed with milk fluid from the prostate before ejaculation. WholeThe sperm development process is called spermatogenesi. In this process, semen are important, albeit intermediate, part.
