The phenomenon of sperm activation in mammals is known as capacitation. It takes about

Options

A. 1hr
B. 5-6 hrs
C. 24 hrs
D. 10-12 hrs

Answer

**Step-by-Step Solution:**

1. **Understanding Capacitation**: Capacitation is the process that sperm undergo to gain the ability to fertilize an egg. It is a crucial step in mammalian reproduction.

2. **Location of Capacitation**: This process occurs after sperm are deposited in the female reproductive tract, specifically in the vaginal tract.

3. **Time Frame for Capacitation**: The question asks how long it takes for sperm to become activated through capacitation after entering the vaginal tract.

4. **Evaluating Options**: The provided options for the time it takes for capacitation are:
- 1 hour
- 5 to 6 hours
- 24 hours
- 10 to 12 hours

5. **Identifying the Correct Answer**: Based on biological studies and understanding of sperm physiology, capacitation typically takes about 5 to 6 hours.

6. **Conclusion**: Therefore, the correct answer to the question is that sperm activation (capacitation) takes about **5 to 6 hours**.
