1 Your testicles actually get bigger during sex…
You’ve probably never noticed this — mostly because you’re busy with, well… other things — but during sexual arousal, your testicles can increase in size by at least 50%. It’s a bit like a basketball suddenly getting bigger in the middle of a game.
Whether it ends up scoring or not, however, is a completely different question. [source]
2 This is why the left testicle hangs lower than the right…
Okay, so we — and by “we” I mean men and anyone currently brushing up on their testicle knowledge — all know that the left testicle usually hangs lower than the right. But do you know why?
Like any good mystery, the answer lies in science. It turns out that the uneven hang is nature’s way of regulating temperature, helping to keep things at the optimal level for sperm production.
That said, the right one deserves just as much love as the left. [source]
3 Your high school boyfriend wasn’t actually lying about “blue balls”…
As much as it may sound like the weakest and most overused excuse to push for some kind of sexual interaction, “blue balls” is actually a real thing.
The basic science behind blue balls is a buildup of pressure caused by increased blood flow to the penis during arousal. And yes — the process can make the testicles appear darker and even slightly bluish compared to their normal color. [source]

4 The older you get, the worse they tend to smell…
Let’s be honest — your balls probably don’t smell amazing to begin with, and unfortunately, the older you get, the worse that smell can become.
The good news? Proper hygiene and giving your “twig” and “berries” some breathing room can significantly reduce the odor. So no, you’re not completely doomed as a man just because you’re getting older. [source]
5 Bigger balls, higher risk of cheating…
As much as this may sound like an old myth, social scientists who have studied testicles suggest that men with larger testicles may be more likely to cheat.
So before committing to a long-term relationship, you might want to ask yourself: “Are these balls big enough to be unfaithful?” [source]
6 Both Jimmy Carter and Adolf Hitler reportedly had only one testicle…
Could there be two men who were greater opposites? Jimmy Carter’s single testicle didn’t seem to affect him in any noticeable way, while Adolf Hitler appeared to struggle with intense personal and physical issues — problems that clearly had consequences far beyond himself. [source]

7 This is why your testicles are insanely sensitive…
Sure, if you’re a man, you already know this — but do you know why that particular area is so sensitive? There are a few reasons.
The most obvious one is that your testicles hang outside the body, but another key factor is that unlike many other nerve-packed parts of your body, they aren’t protected by layers of bone. [source]
8 Smaller balls = louder sex screams…
This one doesn’t really apply to humans. But a study from the University of Cambridge found that, in mammals, there’s an evolutionary trade-off between vocal ability and testicle size.
In short, the smaller the testicles, the higher-pitched and louder the animal’s screams tend to be. [source]

10 A tiny cricket has the biggest balls in the entire animal kingdom…
Katydids are a family of insects within the order Orthoptera, belonging to the long-horned grasshoppers. Why does that matter? Because this tiny insect actually has the biggest balls in the animal kingdom relative to its size.
In fact, their testicles make up about 14% of their total body weight. So the next time you feel like a tough guy with big balls, don’t forget that the katydid has you completely beaten. [source]

Xtra Your testicles can move on their own…
It might sound creepy, but it’s completely normal. Your testicles can actually move up and down thanks to a muscle called the cremaster muscle. This reflex kicks in when you’re cold, stressed, or startled, pulling the testicles closer to the body to keep them warm and protected — and lowering them again when conditions are more relaxed.
Nature’s very own built-in thermostat. [source]
5 Frequently Asked Questions About Testicles
They produce sperm and testosterone, which are essential for reproduction, sex drive, muscle mass, and overall hormonal balance in the body.
Because sperm production requires a slightly cooler temperature than normal body heat. Hanging outside helps regulate that temperature naturally.
Yes, this is completely normal. Most people have one that hangs lower or appears slightly larger, and it’s rarely a cause for concern.
Yes. Age, temperature, arousal, and hormonal changes can all affect size and firmness temporarily or gradually over time.
Sudden pain, hard lumps, swelling, or noticeable changes should always be checked by a medical professional as soon as possible.
