D. About `400 - 450`

Answer

To answer the question of how many eggs are produced by a human female during her reproductive age, we can break down the information step by step:

### Step-by-Step Solution:

1. **Understanding Egg Production**:
- At birth, a female baby has a finite number of eggs (oocytes) in her ovaries. This number is approximately 7 million.

2. **Egg Count at Birth**:
- By the time of birth, the female has around 7 million primary oocytes. This is the total number of eggs she will have throughout her life.

3. **Reduction of Egg Count**:
- After birth, the number of eggs decreases significantly. This reduction continues throughout childhood and into puberty.

4. **Puberty and Menstrual Cycle**:
- Upon reaching puberty, the female begins her menstrual cycle. During each cycle, typically one egg matures and is released (ovulated).

5. **Final Egg Count**:
- By the time a female reaches her reproductive age, the number of eggs has decreased significantly from the original 7 million.
- It is estimated that only about 400 to 500 eggs will be ovulated during her entire reproductive life, as most of the eggs undergo atresia (a process of degeneration).

6. **Conclusion**:
- Therefore, while a female is born with approximately 7 million eggs, the number of eggs that are actually released during her reproductive years is much lower, around 400 to 500.

### Final Answer:
- A human female produces approximately 7 million eggs at birth, but only about 400 to 500 eggs are ovulated during her reproductive age.
