Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the technique used to block the passage of sperm in males. This involves understanding various contraceptive methods.

2. **Identifying Contraceptive Methods**: There are different contraceptive methods available, including surgical procedures. It's important to differentiate between methods used for males and females.

3. **Focusing on Male Contraceptive Methods**: Among the surgical methods for males, we need to identify the one that specifically blocks the passage of sperm.

4. **Defining Vasectomy**: The correct technique for males that blocks the passage of sperm is called "vasectomy." In this procedure, the vas deferens (the duct that conveys sperm from the testicle to the urethra) is cut and sealed.

5. **Mechanism of Vasectomy**: When the vas deferens is cut and tied, sperm cannot travel from the testicles to the urethra. As a result, sperm remains in the testicles and is eventually absorbed by the body.

6. **Conclusion**: Therefore, the technique used to block the passage of sperm in males is "vasectomy," which is a permanent method of contraception.

**Final Answer**: The technique used to block the passage of sperm in males is "vasectomy."
