Examples of oogenesis in the following topics:

  • Oogenesis

    • Oogenesis is the process of the maturation of the female gametes through meiotic division.
    • The menstrual cycle begins with the maturation of oocytes through the process of oogenesis, as well as the concurrent follicle development that stimulates ovulation.
    • Oogenesis starts with the process of developing oogonia, which occurs via the transformation of primordial follicles into primary oocytes, a process called oocytogenesis.
    • Differentiate among the stages of oogenesis the actions of hormones during each stage
  • Gametogenesis (Spermatogenesis and Oogenesis)

    • Spermatogenesis and oogenesis are both forms of gametogenesis, in which a diploid gamete cell produces haploid sperm and egg cells, respectively.
    • The production of sperm is called spermatogenesis and the production of eggs is called oogenesis.
    • Oogenesis occurs in the outermost layers of the ovaries.
    • As with sperm production, oogenesis starts with a germ cell, called an oogonium (plural: oogonia), but this cell undergoes mitosis to increase in number, eventually resulting in up to one to two million cells in the embryo .
    • The process of oogenesis occurs in the ovary's outermost layer.
  • Anatomy of the Female Reproductive System

    • Approximately every month, a process of oogenesis matures one ovum to be sent down the fallopian tube attached to its ovary in anticipation of fertilization.
