Sorry to sound a bit dumb but I have no idea whether it is normal for little boys testicles to leave the scrotum! My ds is 6mo, and the testes are sometimes in the scrotum as you would expect, and at other times the scrotum is empty. It does not appear to hurt him if i feel to see if they are there or not. Don't want to take him to the doctor if this is normal, but i have no experience of little boys, and my dh can't really remember about his boyhood 'bits'. Any advice welcome, Thanks
