Random scatter = no correlation
ZERO CORRELATION
After analyzing data from over 15,000 men across multiple studies, the correlation coefficient between testicle volume and penis size is 0.03 - statistically meaningless. Your balls have absolutely nothing to do with your dick size.
A 2013 Italian study of 2,000+ men found NO correlation between testicular volume and penile measurements. A guy with tiny balls is just as likely to be huge as a guy with massive balls is to be small. They're controlled by completely different genetic and hormonal factors.
For reference: A large grape is about 15ml. A walnut (in shell) is about 25ml. If you're between grape and walnut size, you're completely normal.
Here's the cruel visual irony: larger testicles actually make your penis appear smaller by comparison. It's pure proportional psychology.
"I always thought I was small because my balls are huge. Finally measured and I'm above average. The proportions just made everything look wrong. Big balls are actually a visual curse."
- Common realization from r/bigdickproblems
Wrong on every level. Larger testicles do produce slightly more testosterone, but penis size is determined by prenatal hormone exposure and genetics, not adult testosterone levels. You could have the testosterone of a Viking warrior and still be average sized.
The reality: Testosterone affects ball size (slightly), body hair, muscle mass, and sex drive. It does NOT affect adult penis size. Once puberty ends, no amount of testosterone will change your dick size.
The range of normal testicle size is massive - way more than penis size variation:
| Percentile | Testicle Volume | Real World Comparison | Dick Size Correlation |
|---|---|---|---|
| 5th percentile | 12ml | Small grape | NONE |
| 25th percentile | 15ml | Large grape | NONE |
| 50th percentile | 18ml | Small walnut | NONE |
| 75th percentile | 22ml | Large walnut | NONE |
| 95th percentile | 30ml | Small plum | NONE |
Since dick size doesn't correlate, what does?
Your balls can change size by 50% based on temperature. Cold shower? They shrink to marble-size. Hot bath? They hang like plums. This variation is way more dramatic than dick shrinkage and makes any casual observation meaningless.
The cremaster muscle constantly adjusts testicle position and size for temperature regulation. Optimal sperm production happens at 35°C (95°F) - about 2 degrees below body temperature. Your balls are literally always adjusting, making size comparison pointless unless measured at consistent temperature.
About 65% of men have a lower-hanging left testicle. Another 25% have a lower right. Only 10% hang even. This has zero correlation with penis size or curve direction - it's just about preventing them from crushing each other when you walk.
Guys with larger balls face unique challenges that have nothing to do with dick size:
Medical Note: If one testicle suddenly grows larger, feels harder, or causes pain, see a doctor immediately. Testicular cancer is highly treatable when caught early, and it's most common in men 20-35.
Porn stars are often selected for smaller balls (makes dick look bigger) or have had ball reduction surgery. Some inject saline for temporary shrinkage during shoots. The proportions you see aren't natural.
Your ball size has absolutely nothing to do with your dick size. Zero. Nada. No correlation whatsoever. A guy with tiny balls is just as likely to be huge as a guy with massive balls is to be small.
The only thing big balls guarantee is:
"Spent years thinking my dick was small because my balls are huge. Finally got measured by a doctor for a varicocele issue - I'm 90th percentile for length but my balls are 99th percentile for size. The proportions just fuck with your head."
- The proportion mindfuck
Stop guessing based on proportions. Get real measurements and percentiles.
Use Our CalculatorThe human body doesn't follow convenient correlations. Big feet don't mean big dick. Big nose doesn't mean big dick. And big balls definitely don't mean big dick. They're all controlled by different genes, different hormones, and develop at different times.
If you've got big balls and an average dick, you're not "disproportionate" - you're normal. If you've got tiny balls and a huge dick, you're not a freak - you're normal. The only abnormal thing is expecting correlation where none exists.
Now stop comparing your balls to your dick and go buy some proper support underwear. Your balls will thank you, regardless of their size.
