In hot conditions, the skin loosens to prevent the testicles from overheating. The looser skin allows the balls to hang away from the warm body and encourages airflow around the scrotum to keep the area cool. As such, even in younger people, the testicles will typically sag a bit.

What are signs of your balls dropping?

The main sign: You can’t see or feel the testicle in the scrotum. When both are undescended, the scrotum looks flat and smaller than you’d expect it to be. Some boys have what’s called a retractile testicle. It may move up into their groin when they are cold or scared but moves back down on its own.

Which testicle is usually lower?

Yes. It is common for guys to have slightly different size testicles. Usually, the right testicle is larger than the left. Also, one testicle (usually the left) often hangs lower than the other.
