<s>[INST] Hi, my son is 16months old and i just notice that he could be having undescended testicles.he has been uncomfortable for sometime, pulling at it and at first i thought it was the diapers, until i checked his younger brother and noticed the difference.should i get worried and how can this be corrected?thanks [/INST] Hello. I just read through your question.Undescended testicles are not uncommon. It is not something to be overly worried about because often the testicles will descend on their own. When they don't, they can be pulled down with a very simple surgical procedure. the first step is to alert your pediatrician as to your finding. Most often, the more experienced hands of a pediatrician are able to feel the testicles and rule out the diagnosis. </s>
