Answer

To determine where the corpus spongiosum muscle is present, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure**: The corpus spongiosum is a type of erectile tissue found in the male reproductive system. It is important to know its anatomical position and function.

2. **Identify the Male External Genitalia**: The male external genitalia includes the penis, which is made up of three cylindrical masses of erectile tissue.

3. **Differentiate the Types of Erectile Tissue**:
- There are two corpora cavernosa, which are located on the dorsal side of the penis.
- The corpus spongiosum is located on the ventral side and surrounds the urethra.

4. **Locate the Urethra**: The corpus spongiosum contains the penile urethra, which is crucial for both urinary and reproductive functions.

5. **Eliminate Incorrect Options**:
- The corpus spongiosum is not present in the testes or the epididymis, as these structures are not part of the penis.
- The corpus spongiosum is specifically associated with the penis.

6. **Conclude the Answer**: Therefore, the corpus spongiosum muscle is present in the penis.

### Final Answer:
The corpus spongiosum muscle is present in the penis.
