Is it normal to have a bigger testicle?

Yes, it is normal to have one testicle that is larger than the other. The difference is usually not significant and does not cause any problems. However, if one testicle is significantly larger than the other, it may be a sign of a medical condition, such as testicular cancer. If you are concerned about the size of your testicles, it is important to see a doctor to rule out any underlying medical conditions.
