The top of the penis is cut open but not all the way through to the other side. This is done by cutting the shaft of the penis in half while leaving the head whole. When this is done, your penis may look like it’s curling inward when you have an erection. This is done by splitting the entire penis in half, from the tip of the head all the way down to the bottom of the shaft. A meatotomy expands the hole for your urine to come out of. Your surgeon may recommend getting a meatotomy done first. This is done by cutting the head of the penis in half, leaving the rest of the shaft intact.
There are many different ways to split the penis, and each procedure has its own name. Penis splitting is often used as an umbrella term.
