If your 9-year-old son's penis has not grown since he was born, he could have a condition called micropenis
or micro-phallus. This condition can be treated by a doctor, though I'm not sure if a pediatrician
or a urologist
would be the one to do this. I believe treatment involves applying a testosterone
creme to the penis. It will be important that he be assessed for this sooner rather than when he is older, because the window of opportunity to correct this condition will be decreased. In other words, he might need all available time to turn this condition around. Your son might also need to have hormone tests to clarify if his overall hormonal system is working properly. Again, I don't know how much of this would be done by a a Pedi, versus a urologist versus an endocrinologist
. Do not wait to have your son assessed by a competent doctor. If not treated in time, his penis could stay tiny for the rest of his life, which no doubt would be devastating. He could suffer much rejection when trying to find a mate and it could interfere with his ability to have children.
