Answer

To solve the question regarding which parts of the human reproductive system (male or female) are located outside the body, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Male Reproductive Parts**:
- The male reproductive system includes several parts such as the testes, vas deferens, seminal vesicles, and penis.
