Blue balls typically lasts only a few minutes. In rare cases, the discomfort can linger for a few hours, but it always resolves on its own once arousal fades. The sensation is real, it has a medical name (epididymal hypertension), and it’s not dangerous.
What’s Actually Happening
During sexual arousal, the arteries supplying blood to the genitals widen, flooding the area with extra blood flow. At the same time, the veins that normally carry blood away temporarily constrict. That’s what produces an erection and causes the testicles to swell slightly. If arousal continues for a while without orgasm, that pooled blood creates a feeling of pressure, heaviness, or aching in the testicles.
After ejaculation, or once arousal simply fades, the blood vessels return to their normal size. The swelling goes down, and the discomfort disappears. There’s no lasting effect on the testicles or reproductive health.
What It Feels Like
Most people describe blue balls as a dull ache or heaviness in one or both testicles. It’s generally mild. Despite the name, noticeable color change is uncommon. The testicles may look slightly darker due to the extra blood, but they don’t literally turn blue in most cases. The symptoms pass quickly once the genitals return to their unaroused state.
How to Make It Go Away Faster
Ejaculation is the most direct fix, since it triggers the blood vessels to relax and release the trapped blood. But it’s far from the only option. Several other approaches can speed things along:
- Exercise or physical exertion: Working out, or even lifting something heavy, diverts blood flow from the testicles to the large muscles that need it. This can provide surprisingly fast relief.
- Cold application: A cold compress on the area, or a cold shower, helps constrict the dilated blood vessels and also reduces arousal.
- Over-the-counter pain relief: Ibuprofen can reduce both swelling and discomfort. Acetaminophen helps with pain alone.
- Distraction: Shifting your focus to something completely nonsexual, like reading, working, or watching TV, lets arousal fade naturally.
- Deep breathing: Slow, deliberate breathing lowers your heart rate, which reduces vascular pressure in the testicles.
- Urinating: Emptying your bladder can relieve some of the compression in the area.
You don’t need to try all of these. For most people, a combination of distraction and light physical activity is enough to resolve the discomfort within minutes.
When the Pain Might Be Something Else
Blue balls is mild and temporary. If what you’re feeling doesn’t match that description, the cause could be something different. Two conditions worth knowing about are testicular torsion and epididymitis.
Testicular torsion happens when the cord supplying blood to a testicle twists, cutting off circulation. It causes sudden, severe pain, usually in one testicle, and it’s a medical emergency. Without treatment within six to eight hours, the testicle can be permanently damaged. Surgery is typically required to correct it.
Epididymitis is an infection or inflammation of the tube behind the testicle. Unlike torsion, the pain builds gradually rather than hitting all at once. It requires antibiotics to treat and often anti-inflammatory medication for the swelling.
Seek immediate medical care if you experience sudden, severe testicular pain, or if the pain comes with nausea, fever, chills, or blood in your urine. Mild testicular pain that persists for more than a few days, or any lump or swelling you can feel, also warrants a visit to a doctor. Blue balls doesn’t last days, doesn’t involve lumps, and doesn’t come with fever. If your symptoms include any of those features, something else is going on.
