Spermatogonia (Spermatogonium, Pl. Spermatogonia)

Spermatogonia is a cell that is the precursor of spermatozoa in the process of spermatogenesis. Spermatogonia appear in the testicles during the fetal development stage, but before puberty their reproduction practically does not occur. They are stem cells of the convoluted seminiferous tubules and periodically divide by mitosis, resulting in the formation of spermatocytes. Thus, spermatogonia are the first step in the chain of transformation of stem cells into mature sperm.

Spermatogonium (Spermatogonium, plural. Spermatogonia) are cells that play an important role in the process of spermatogenesis - the formation of sperm in the male gonads. They are the precursors of sperm and ensure constant renewal of male gametes.

Spermatogonia appear in the testicles of men already during embryonic development and then continue to multiply throughout the man’s life. Until the onset of puberty, practically no reproduction occurs, but after the onset of puberty they begin to differentiate and give rise to spermatocytes.

Spermatogonia are stem cells and periodically divide mitotically to form two daughter cells - one remains a spermatogonia and the other continues to differentiate into spermatocytes. There are two types of spermatogonia - A and B. Type A spermatogonia are an integral part of the stem line and can produce either another type A spermatogonia or type B spermatogonia. Type B spermatogonia, in turn, can give rise to more differentiated cells - spermatocytes.

Spermatogonia are important cells for maintaining the constancy of the sperm population and therefore male reproductive capacity. The study of the process of differentiation of spermatogonia is an important area in the research of male reproductive biology and may be of practical importance for the development of methods for treating male infertility.

Spermatogonia are the precursors of sperm from a group of primary germ cells that reproduce by mitosis to form first-order spermatocytes. They divide by fragmentation of the division spindle, which leads to the appearance of identical spermatogonia, from which one second-order spermatocyte is formed - the first arrival of sperm at this time interval (pause) contains immature sperm cells (spermatozoa), as well as differentiating spermatogonia; the first differentiate into spermatos and presper
