OOGENESIS Meaning and
Definition
-
Oogenesis is the process of egg cell development, specifically in female organisms. It is the formation and maturation of ova or eggs within the ovaries of females. Oogenesis is a complex and highly regulated process that begins during embryonic development and continues throughout the reproductive life of the individual.
During oogenesis, germ cells in the female's ovaries undergo a series of cellular divisions and differentiations, ultimately resulting in the formation of mature eggs. The process includes the formation of primary oocytes, which undergo meiosis I to produce secondary oocytes. The secondary oocytes then go through meiosis II, resulting in the formation of a mature ovum.
Oogenesis is influenced by various hormones, with follicle-stimulating hormone (FSH) and luteinizing hormone (LH) playing crucial roles in regulating the development and maturation of the oocytes. FSH stimulates the growth of the ovarian follicles, while LH triggers ovulation and the release of the mature ovum from the ovary.
Overall, oogenesis is a fundamental process that ensures the production of viable female gametes necessary for sexual reproduction. It is an intricate and coordinated sequence of cellular events that ensures the development and release of mature eggs, enabling the continuation of a species' reproductive cycle.
