Verified step by step guidance

1. Understand that oogenesis is the process of egg cell development in females.
2. Recognize that oogenesis begins before birth, with the formation of primary oocytes during fetal development.
3. Note that after birth, oogenesis is paused and resumes at puberty, continuing until menopause.
4. During oogenesis, each primary oocyte undergoes meiosis, but only one mature ovum is produced, along with polar bodies that are not viable.
5. Remember that unlike spermatogenesis, which produces four viable sperm cells, oogenesis results in one viable ovum from each primary oocyte.
