Consult to the surgeon Clinical diagnosis we have to make

Looks like retractile testis.. needs clinical examination.. consult surgeon

If ur right testicle is goes into ur body then u have congenital hernia on that side and if it is smaller than ur left side it means that ur right testis is atrophied...So do an usg to confirm it and consult a surgeon to diagnose clinically what your suffering from...Usually the left testis is seen lower than the right side..,,

Normally  both  testicles are  at different levels. So its  absolutely normal and  nothing to  worry. Your right  testicle is retractile and  hence  goes  up inside  the  body. This too is  not a serious problem at all

Best to get examined by good general surgeon

As far as position and size is concerned it's ok If testis is very retractable high better to get it fixed
