Hi. Several years back i kicked my brother in the balls. He had to go to a doctor, and was peeing out blood. We are now teenagers, and have discussed what happened when we were kids. I am fearful he may not be able to have children. He says he still produces sperm, but adds that his left ball is more sagged than the right one. He says it feels "broken" inside. This puts great sadness on me, as i fully regret my actions as a child. We are both wondering if this will cause future damage to him as he grows up, or if it's nothing to worry about. Thankyou.
