Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
There could be many reasons for such hypopigmentation
, right from being nutritional cause to infections. YOu may need a biopsy
of the skin over the scrotum
to confirm .I would advise you to take up some snaps and put it on the HCM question so that we can have a better look at what you are meaning to say.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
