###Human: Would the surgery to correct undescended testicle cause any side effect? ###Assistant: Hi. I suggest that surgical correction should be done to bring it down as low as possible. Reason being, it permits self palpation of testis for early detection of any tumor. Frequent ultrasound is not feasible or practical to think of. Self palpation can be done every day. Ultrasound cannot be done every day. Surgery is a minor one. If it is already shrunken, in my opinion the surgeon may suggest removal of it. Do not be afraid and go ahead.
