Spermatogenesis is the process of the production of sperms from the immature germ cells in males. It takes place in seminiferous tubules present inside the testes. During spermatogenesis, a diploid spermatogonium (male germ cell) increases its size to form a diploid primary spermatocyte.

Rounded immature sperm cells undergo successive mitotic and meiotic divisions (spermatocytogenesis) and a metamorphic change (spermiogenesis) to produce spermatozoa. In spermatogenesis, meiosis results in the formation of. asked Apr 28, 2019 in Anatomy & Physiology by shnice2. A. one sperm cell with 23 chromosomes.

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.

We call gametogenesis in the male spermatogenesis and it produces spermatozoa. In the female, we call it oogenesis.

2018-12-06 · Spermatogenesis is a complex process involving the expression of a large number of genes [ 1 – 2 ]. The function of many of these genes remains unknown, resulting in an incomplete understanding of this process, sperm function and the causes of male infertility [ 3 ]. Se hela listan på biologywise.com Spermatogenesis Definition It is the male version of gametogenesis which results in the formation of mature male gametes.
