When do the egg cells of a human female begin meiosis ? Are any oogonia added after birth ?

Explanation

### Step-by-Step Solution:

1. **Understanding Oogenesis**: Oogenesis is the process of forming female gametes (egg cells or ova) in females. It is a type of gametogenesis that involves meiotic division.

2. **Initiation of Meiosis**: The egg cells of a human female begin meiosis during embryonic development. This means that the process starts while the female fetus is still in the womb.

3. **Formation of Oogonia**: During embryogenesis, approximately 2 million gamete mother cells, known as oogonia, are formed. These oogonia are the precursors to the egg cells.
