They become atretic; fewer than 500 will be ovulated
At puberty, what is the approximate total number of female germ cells in the ovary?
Approx. 400
How long does the process of spermatogenesis and spermiogenesis take?
Approx. 74 days
What is the total number of female germ cells in the ovary in the fifth month of prenatal development?
Approx. 7 million
Study Notes
Female Germ Cells
- Around 1-2 million female germ cells are present in the ovary at birth.
- During childhood, most oocytes undergo atresia, a process of degeneration and resorption.
- At puberty, the approximate total number of female germ cells in the ovary is around 300,000-400,000.
Spermatogenesis
- The process of spermatogenesis and spermiogenesis takes around 64-74 days.
Prenatal Development
- In the fifth month of prenatal development, the total number of female germ cells in the ovary is around 2 million.
