Is it bad if one testicle is larger than the other 2?

A slight difference in the size of the testicles is normal. In fact, it's common for one testicle to be larger than the other by up to 1 centimeter. This difference is usually not noticeable and doesn't cause any problems.

However, a significant difference in the size of the testicles could be a sign of an underlying medical condition, such as:

- Testicular cancer

- A varicocele (enlarged veins in the scrotum)

- An infection or inflammation of the testicle

- A hormonal imbalance

If you're concerned about the size of your testicles, it's important to see a doctor for evaluation. They can determine if the difference in size is normal or if it's a sign of a more serious problem.
