In man sperms move after ejaculation at a rate of nearly

Options

A. 2 to 4 mm/minute
B. 2 to 4 feet/minute
C. 2 to 4 inches/minute
D. 2 to 4 cm/minute

Explanation

To solve the question about the rate at which sperm move after ejaculation in men, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the rate of movement of sperm after ejaculation in men.

2. **Identify the Options**: The options provided are:
- A) 2 to 4 mm per minute
- B) 2 to 4 feet per minute
- C) 2 to 4 inches per minute
- D) 2 to 4 cm per minute

3. **Recall Relevant Information**: It is known from biological studies that sperm have a relatively slow rate of movement in the female reproductive tract after ejaculation.

4. **Evaluate the Options**:
- **Option A (2 to 4 mm per minute)**: This is a very slow rate and is consistent with the known movement of sperm.
- **Option B (2 to 4 feet per minute)**: This is too fast for sperm movement.
- **Option C (2 to 4 inches per minute)**: This is also too fast for sperm movement.
- **Option D (2 to 4 cm per minute)**: This is still faster than the typical movement rate of sperm.

5. **Select the Correct Answer**: Based on the evaluation, the correct answer is **Option A: 2 to 4 mm per minute**. This aligns with the biological understanding of sperm motility.

### Final Answer:
The rate at which sperm move after ejaculation in men is nearly **2 to 4 mm per minute**.
