What Are “Blue Balls”?

Understanding Testicle Discomfort After Sexual Arousal

You may have heard the term “blue balls” before—usually in jokes or conversations about sex. While it might sound funny, it’s actually a real physical feeling some people experience. The medical name for this is epididymal hypertension, but don’t worry—it’s not dangerous and usually goes away on its own.

Why Do “Blue Balls” Happen?

When you get sexually aroused (excited), more blood flows to your genitals, including a small tube behind your testicles called the epididymis. This tube helps move sperm. If you don’t reach orgasm (the climax that usually happens during ejaculation), the extra blood can hang around a little longer, which may lead to:

• A heavy or full feeling in your testicles
• Mild pain or pressure
• Discomfort that can feel a bit annoying

The good news? It’s not harmful, and the feeling goes away over time as blood flow returns to normal.

How Can I Feel Better?

Some people think the only way to fix this is to have sex or orgasm, but that’s not the only solution. Here are a few ways to ease the discomfort:

• Masturbation – This can help release the built-up pressure.
• Distraction – Focus on something non-sexual like video games, sports, or a hobby.
• Take a shower or bath – A warm bath can help relax your body.
• Urinating (peeing) – Sometimes this can reduce the pressure.

Most of the time, just giving it a little time is enough. The symptoms usually fade as your body calms down.

Will My Testicles Actually Turn Blue?

Nope—your testicles won’t actually turn blue. The name “blue balls” is just slang and not based on real color changes.

When Should I See a Doctor?

Testicle pain isn’t always from “blue balls.” Sometimes it can be something more serious. You should talk to a doctor if:

It’s always better to ask a health professional if something doesn’t feel right. Don’t be embarrassed—they’re there to help.
