(A) Spermatogenesis results in four mature sperm cells, whereas oogenesis results in one mature egg cell. During oogenesis, meiosis results in ________. A) four equally sized cells that stop dividing in meiosis I Spermatogenesis results in four motile male gametes (sperms) from a spermatogonium and oogenesis results in a single non-motile female gamete (ovum) from an oogonium. Spermatogenesis is the process that results in the formation of sperms and it normally occurs in the seminiferous tubules of the testes. Generally, the process results in the formation of spermatids and spermatozoa. The type of cell division that facilitates the process is known as meiosis.

Location in humans. Spermatogenesis takes place within several structures of the male reproductive system. Spermatogenesis is the process of formation of mature sperm cells through a series of mitotic and meiotic divisions along with metamorphic changes in the immature sperm cell.

Figure \(\PageIndex{1}\): Spermatogenesis: During spermatogenesis, four sperm result from each primary spermatocyte, which divides into two haploid secondary spermatocytes; these cells will go through a second meiotic division to produce four spermatids. Meiosis begins with a cell called a primary spermatocyte. Abstract.

Spermatogenesis is the male version of gametogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material. In mammals, it occurs in the male testes and epididymis in a stepwise fashion that takes approximately 64 days. What Is Spermatogenesis?
