Peyronie's disease is a condition where scar tissue builds up in the penis, causing it to curve or bend. It's like when you get a scar from a cut or a burn, but in this case, it's inside the penis. One in five men will experience some degree of curvature in their lifetime, so it's more common than you think!
The causes of Peyronie's can be mysterious, but injury and age are two big contributors. It's like when you trip and fall, or get a little older and your body starts to slow down - sometimes things just don't work like they used to! But don't worry, there are treatments available to help straighten things out.
