Your hymen is a thin, fleshy membrane that surrounds the opening of your vagina. Usually, the hymen has one moderate-sized hole. A cribriform hymen can cause issues with periods (menstruation) and penetrative sex.
Learning your genital anatomy is different from what’s expected can stir up a lot of emotions and concern. Know that a cribriform hymen is just that — a difference. It may go away on its own, or a simple surgery can treat it.
With a cribriform hymen, discharge can flow out of your vagina, like blood from periods (menstruation). But blood may come out slower than usual. This means your periods may last longer than normal — perhaps by four to seven days.
Another symptom of a cribriform hymen is having difficulty comfortably inserting an object into your vagina. For example, you may:

A healthcare provider may detect a cribriform hymen at birth during a physical examination of a newborn. But many people don’t know they have one until puberty or later.
A healthcare provider (usually a gynecologist) can make the diagnosis by looking closely at your hymen during a pelvic exam.

The surgery is called a hymenotomy. Your healthcare provider cuts away the extra tissue, leaving only one opening that’s a typical size. It’s a minor outpatient procedure, which means you can go home the same day.
Your provider will talk to you about options for anesthesia to manage pain during the procedure. You may need stitches afterward, which usually dissolve on their own.
A cribriform hymen may cause pain and limit activities, but it’s not a dangerous condition.
Sometimes, it goes away on its own as a child grows. Your hymen may tear or wear down from everyday activities, like riding a bike or gymnastics. This may naturally open it up.
If you choose to have a hymenectomy to treat a cribriform hymen, the extra tissue won’t grow back.
If you want to know more about your hymen, consider asking a healthcare provider the following questions:
There’s nothing you can do to control the shape of your hymen. And everyone’s hymen is different. If you have a cribriform hymen, it may not cause any symptoms. But if you’re having issues with tampon use or penetrative sex, it’s a good idea to see your healthcare provider. Talking about your genital anatomy or sex life can be difficult. But it’s nothing to be ashamed of. It’s an important part of your health. And your provider is there to help you, not judge you.
