My son is 10 months old. Now, he got a problem like, one of his testis is not in the scrotum. When we scan it, it was given in the report as the left side of the testis is present in the left side external inguinal ring measuring 15 * 6mm. So whether operation is the only solution for him? Or we can wait for few more years for this problem? Kindly suggest me a solution for this issue. We are really worried.
