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.

WebThis cell is haploid and must go through another meiotic cell division. The cell produced at the end of meiosis is called a spermatid and when it reaches the lumen of the tubule and grows a flagellum, it is called a sperm cell. Four sperm result from each primary spermatocyte that goes through meiosis. WebThe primary spermatocytes undergo meiosis 1 to form secondary spermatocytes, which are haploid. Secondary spermatocytes undergo meiosis 2 to form spermatids. A single, primary spermatocyte may produce four spermatids. These spermatids then undergo spermiogenesis, differentiating into mature sperm cells.
