Options

A. 80000
B. 600000
C. 160000
D. 1600000

Answer

To solve the question regarding the total number of primary follicles in each ovary of a human female at puberty, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Oogenesis**:
- Oogenesis is the process of egg (ovum) development in females. It begins during embryonic development when the female fetus is forming.

2. **Follicle Formation**:
- During fetal development, approximately 1 million primordial follicles are produced in each ovary. These follicles are in an immature state.

3. **Follicular Atresia**:
- Many of these primordial follicles undergo degeneration, a process known as follicular atresia. This means that not all the follicles survive to become primary follicles.

4. **Primary Follicles at Puberty**:
- By the time a female reaches puberty, the number of primary follicles that remain in each ovary is significantly reduced. Research indicates that this number ranges from about 60,000 to 80,000 primary follicles in each ovary.

5. **Conclusion**:
- Therefore, at puberty, the total number of primary follicles in each ovary of a human female is approximately 60,000 to 80,000. Among the given options, the closest and correct answer is 80,000.

### Final Answer:
The total number of primary follicles in each ovary of a human female at puberty is about **80,000**.
