My son just turned 8 and he can't pull the foreskin back over the head of his penis yet. Now I know that he may not be able to do so until his teens... but I am concerned because his father has a tight foreskin. It's not really severe for his father because intercourse is not painful and he can stretch the foreskin over the glans to wash (although it is rather tight). But I'm wondering if this is hereditary?? Is this something I should bring up now to my son's pediatrician or should I just wait and see? I'm wondering... if it is hereditary, maybe there is some treatment that can be started now to avoid possible circumcision later on?? Any advice would be appreciated.
