Vasectomy: Procedure, Effectiveness, Recovery & Considerations

What Is a Vasectomy?

A vasectomy is a surgical procedure that cuts or seals the vas deferens—the tubes that carry sperm from the testicles to the penis. This prevents sperm from being ejaculated, rendering the man sterile.

Effectiveness

Over 99% effective (failure rate < 1%).

Procedure & Recovery

• Relatively simple, often done under local anesthesia in an outpatient setting.
• Most men recover within a few days.

Important Facts

• Sperm production continues, but sperm are reabsorbed by the body.
• Does not affect sex drive, sexual function, or ability to orgasm.
• Does not protect against sexually transmitted infections (STIs)—condoms are still needed for STI prevention.
• Permanent—should only be considered if certain about not wanting more children.
