HiCustomer Thanks for the question.
The most common reason for itching around the scrotum and in the creases, is fungus or "jock itch". A fungacide is usually recommended and works is Lotrinin AF or similar over the counter Antifungals.

I would recommend trying Lotrimin AF Cream. If after a weeks trial that has not improved, you need to see a physician, preferably a dermatologist.
I hope this answers your question, but if not please get back to us. Good Luck and good health. Dr. L
