Human Reproduction: Gametogenesis
Hardbiology
Primary oocyte is arrested at which meiotic stage until puberty?
Select the correct option:
Solution
Incorrect! Answer:
Prophase I (diplotene)
- Oogenesis: The process of female gamete formation begins during the embryonic development stage.
- Initiation: Millions of oogonia are formed in each fetal ovary; no more are added after birth.
- Early Arrest: These cells start division and enter Prophase-I of the meiotic division and get temporarily arrested at that stage. Specifically, the arrest occurs at the Diplotene stage (also called the dictyate stage).
- Puberty: This primary oocyte remains arrested within the primary follicle until puberty, after which hormonal cycles cause it to complete the first meiotic division just before ovulation.
