Vasectomy Basics

How does vasectomy prevent pregnancy?

Sperm are made in a man’s testes. During sexual climax, the sperm travels through two tubes (the right vas and left vas) in the scrotum, mix with semen (from the prostate and seminal vesicles), and come out of the penis. In a vasectomy, these tubes are blocked so the sperm cannot reach the semen. As a result, you will ejaculate semen without sperm.

Also keep in mind that the sperm makes up a minute portion of the ejaculate, approximately 1% of the volume. Therefore, you will not notice any change in the ejaculation post-vasectomy. Your sexual experience, erections, performance, ejaculations are essentially unchanged.

Only change is: No more sperm, no more pregnancy!

To understand what happens during a No-Scalpel Vasectomy procedure, first review this diagram to see how the male anatomy normally functions. The testicles produce sperm that travel through a pair of tubes called the Vasa Deferens. You can easily feel them through the scrotal skin, like firm spaghetti-sized tubes on either side of the penis. These tubes carry sperm from the testicles out through the penis. The NSV procedure simply interrupts the flow of sperm by cutting the sperm tubes and blocking their ends.

Before making the decision to have your NSV, why not take a virtual run-through of the preparations, procedure, and recovery to see what you can expect from Dr. Crouse and your NSV from start to finish.
