Spermatogonia is one of the germ cells, and spermatogonia are shown when examining sperm quality or in reports. The most important feature of spermatogonia is that they divide indefinitely throughout their lives. Continuous division and differentiation produces spermatogonia, thus increasing the number of spermatogonia, which are present early in the process of male spermatogenesis. A male spermatogonia can divide into hundreds of spermatocytes, which continue to extend and evolve, eventually forming spermatozoa. Spermatozoa can always continue to be produced because of the spermatogonia that are constantly dividing and evolving. Spermatogonia examination is mainly for checking the quality of sperm and the development of male testicles, if any abnormality is found it can be treated according to the situation, so spermatogonia is very important for men.
