Pruritus scroti is when the skin around a boy's private parts (called the scrotum) becomes super itchy and annoying. Sometimes, the skin might turn red or even get little bumps on it. It's like when you have a mosquito bite and it's really itchy, but it happens in a different part of the body.
The itchy feeling can happen because of a few different reasons. Sometimes, it's because of something called jock itch, which is kind of like a fungus (like when you get athlete's foot on your toes). Other times, it can happen because of allergies to things like soaps or even laundry detergent.
The good news is that there are things you can do to help the itching go away. Sometimes, the doctor will give you a special cream to put on your skin that will help get rid of the itchiness and make the skin feel better. Other times, you might just need to use a different soap or laundry detergent.
It's important to remember to tell a grown up if your private parts are feeling itchy or uncomfortable. They can help you figure out what might be causing it and how to make it feel better.
