<s>[INST] My son six-month old and both undescended testicles. his scrotum is very small.underdeveloped. The pediatrician said, if the scrotum is too small,the surgery results will not be good. So suggested us to stretch the baby s scrotum 3 hours a day to make the skin bag large. We want to ask, are there any else methods that can make the scrotum be normal size??? We are very worried. Thanks a lot!!! [/INST] Hi, If the testes are really descended, this needs a surgery to bring back the testes into scrotal sac. Otherwise, this will cause trouble in future including infertility and abdominal pain. In my opinion, stretching of an empty scrotum will not be helpful. Kindly take him to a pediatric surgeon. If both testes are descended with very small scrotum, you may be asked for an ultrasound scan and few blood tests including karyotyping to ascertain the sex. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
