Hi Mich, We had something similar that was noticed at the 8 month check, the health visitor and the subsequent check with the GP both thought the testicles hadn't descended. So we were referred to a consultant as Kings, and he said that they were actually retractable, which meant that he didn't need the operation (a very relieved mother). We were just told to have a check up with our GP annually to check this was still the case. So hopefully your little boy won't need the operation either. Hope that helps.
