What is Oogenesis?
Oogenesis is the complex process of egg cell development in females. It begins before birth, with oogonia, which differentiates into primary oocytes. These primary oocytes get arrested in the prophase I of meiosis. During a woman’s menstrual cycle, some primary oocytes get activated and continue meiosis. Ovulation leads to the release of the secondary oocyte from the Graadian follicle. If fertilization occurs, that would lead to the completion of meiosis II, forming a mature ovum and a second polar body. If fertilization does not occur meiosis II will not take place and the follicle will denature and get ejected out of the body with menstrual blood.
What is Oogenesis?
Oogenesis is the process that describes how a mature egg in females develops. Oogenesis is part of a very important process called gametogenesis. Oogenesis helps to ensure that the human species keeps on continuing on the face of the Earth. Oogenesis describes the remarkable journey an oocyte undergoes after it originates from the primordial germ cell. The whole intricate process of oogenesis takes place in the ovarian follicles present in the ovaries. Understanding the process of oogenesis helps us to comprehend female fertility, the menstrual cycle, and female reproductive health.
