Answer

To solve the question regarding the statements about the second meiotic division during oogenesis, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Oogenesis**: Oogenesis is the process of egg (ovum) formation in females. It begins during fetal development and continues after puberty.

2. **Statement I: Completed after puberty**:
- This statement is **correct**. The second meiotic division is completed after puberty, specifically during the menstrual cycle when a secondary oocyte is released.

3. **Statement II: Completed first before puberty**:
- This statement is **incorrect**. The second meiotic division does not complete before puberty; it remains arrested in prophase I until puberty.

4. **Statement III: Completed after ovulation**:
- This statement is **incorrect**. The second meiotic division is completed only if fertilization occurs, which happens after ovulation. Thus, it is not accurate to say it is completed after ovulation.

5. **Statement IV: Completed before fertilization**:
- This statement is **incorrect**. The second meiotic division is completed during fertilization, not before it.

6. **Statement V: Completed during maturation phase**:
- This statement is **correct**. The second meiotic division occurs during the maturation of the oocyte, particularly at the time of fertilization.

### Summary of Correct Statements:
- Correct statements: I and V.
- Incorrect statements: II, III, and IV.

### Conclusion:
Out of the five statements, **2 statements (I and V) are correct**.

### Final Answer:
**2 statements are correct.**
