I was with my boyfriend last night and noticed a small dark patch on the front of his scrotum.  He didnt seem to notice it and I didnt ask him about it, its never been there before.  Its not red, more of a very dark ash color.  Any ideas?  Hes a healthy 25 year old if that helps.  Thanks
Hi and welcome to Chat Doctor. Thank you for your query. I am Chat Doctor, I understand your concerns and I will try to help you as much as I can. I don't think this is related to testicles, and it sounds more likely to be dermatologist condition. So he should do dermatologist examination to see if there is dysplasia nevus or hyperpigmentation due to other skin disorders. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
