Vas-occlusive contraception is a method used by some people to prevent pregnancy. Basically, it involves a tiny surgery that blocks or closes the tubes called vas deferens that carry sperm from your testicles (where they are made) to your penis (where they come out).
Imagine a garden hose that runs from the water source to a plant. The vas deferens is like that hose and the sperm are like the water. When you get this surgery, the doctor will find the two tubes that are called the vas deferens and will make a small cut. Then, they will either tie them or put a tiny clip or plug in them, sort of like a clamp so that the sperm cannot go through them.
So, if your sperm cannot get through these tubes, they cannot reach the eggs in the female body and fertilize them. And if the eggs are not fertilized, then a person can’t get pregnant.
The good thing about vas-occlusive contraception is that it’s a really effective form of birth control with a very low failure rate. But it’s also a permanent method of birth control, so it’s important to make sure not to regret it once you have had it.
