Primary vs secondary spermatocyte
WebSlide 273, obtained from a pre-adolescent, shows what the testis looks like before puberty.The seminiferous tubules slide 273 View Image contain mostly Sertoli cells (oval nuclei) and spermatogonia (round nuclei), although there may be an occasional primary spermatocyte. Most of the cells in the interstitial tissue between the tubules are … WebMale Reproductive System: Spermatogenesis. The production of sperm and eggs/ova (gametes) is a procedure called gametogenesis (spermatogenesis and oogenesis). Gametogenesis involves two rounds of meiotic cell division, in which one diploid cell gives rise to 4 haploid cells. This diagram shows the processes involved in spermatogenesis.

WebJun 8, 2024 · Key Points. Gametogenesis, the production of sperm (spermatogenesis) and eggs (oogenesis), takes place through the process of meiosis. In oogenesis, diploid oogonium go through mitosis until one develops into a primary oocyte, which will begin the first meiotic division, but then arrest; it will finish this division as it develops in the follicle, …
