Multiple choice questions (MCQs)
choose the correct option
Which of the following represents a condition where the mortility of sperms is highly reduced?

Options

A. Azoospermia
B. Polyspermy
C. Oligospermia
D. Asthenospermia

Answer

To solve the question regarding the condition where the motility of sperm is highly reduced, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a condition that specifically indicates reduced motility of sperm.

2. **Identify the Options**: Although the options are not provided in the question, we can infer from the video transcript that the relevant terms include:
- Azoospermia
- Polyspermia
- Oligospermia
- Asthenospermia

3. **Define Each Term**:
- **Azoospermia**: This condition is characterized by the absence of sperm in the semen. Therefore, motility cannot be assessed since there are no sperm present.
- **Polyspermia**: This term indicates an excessive number of sperm. Here, the motility is not reduced; in fact, there are many sperm present.
- **Oligospermia**: This condition refers to a lower than normal sperm count. While the count is reduced, it does not specifically indicate reduced motility.
- **Asthenospermia**: This condition specifically refers to reduced motility of sperm. Sperm may be present, but they are unable to move effectively.

4. **Analyze the Conditions**: Among the options, only asthenospermia directly addresses the issue of reduced motility. The other conditions either refer to the absence of sperm or an increased count, which do not relate to motility.

5. **Select the Correct Option**: Based on the definitions and analysis, the correct answer is **Asthenospermia**.

### Final Answer:
The correct option is **D. Asthenospermia**.
