WebOogenesis. Oogenesis is the production of secondary oocytes from the primordial germ cells. It takes place in the ovaries. As a foetus early in development, a female has around 6 million eggs in her ovaries. This number is steadily reduced throughout gestation, so it’s already down to 1-2 million when the baby girl is born. Web28 de abr. de 2024 · Oogenesis is the process of development of female gametes (also called ova or eggs), that takes place in ovaries. The process of oogenesis begins before birth and then development is suspended until puberty. Development resumes with ovulation and the final step (meiosis II) is completed only if fertilization occurs.
WebOogenesis also occurs within archaeocyte masses, as does the spermatogenesis. However, oogenesis is probably a relatively rapid process, since few oocytes have been observed even by light microscopy and paraffin sections. The smallest identified oocyte is 10 μm in diameter and is surrounded by archaeocytes that act as nurse cells.
