Answer

To answer the question of how many primary follicles are left in each ovary at the time of puberty, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Follicles**:
- Primary follicles are the initial stages of follicle development in the ovaries. They contain immature oocytes and are crucial for the process of oocyte maturation.

2. **Development of Follicles**:
- During fetal development, a female's ovaries produce a large number of primary follicles. However, many of these follicles undergo atresia (degeneration) before puberty.

3. **Number of Follicles at Puberty**:
- By the time a female reaches puberty, the number of primary follicles in each ovary significantly decreases. Research indicates that the number of primary follicles left in each ovary at puberty is typically between 60,000 to 80,000.

4. **Evaluating Options**:
- The question may provide multiple-choice answers. The correct range for the number of primary follicles at puberty is 60,000 to 80,000 in each ovary. Other options such as 7 million or 10,000 to 20,000 are incorrect.

5. **Conclusion**:
- Therefore, the correct answer to the question is that at the time of puberty, there are approximately **60,000 to 80,000 primary follicles left in each ovary**.
