The entire process of spermatogenesis can be broken up into several distinct stages, each corresponding to a particular type of cell in humans. In the following table, ploidy, copy number and chromosome/chromatid counts are for one cell, generally prior to DNA synthesis and division (in G1 if applicable). The primary spermatocyte is arrested after DNA synthesis and prior to division.

WebFour sperms result from each primary spermatocyte that goes through meiosis. Spermatogenesis. During spermatogenesis, four sperms 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. WebApr 20, 2024 · An oocyte is an immature egg (an immature ovum). Oocytes develop to maturity from within a follicle. These follicles are found in the outside layer of the ovaries. During each reproductive cycle, several follicles begin to develop. Typically, only one oocyte each cycle will become a mature egg and be ovulated from its follicle. WebFeb 23, 2024 · The next step of spermatogenesis is meiosis – a complex process with the main goal to reduce cell ploidy from 2n (diploid) to 1n (haploid) .
