What is the hymen?

Here are some facts about the hymen:

  • The hymen is a thin membrane-like tissue that’s located inside the opening of the vagina

  • The shape, size, and flexibility of a hymen is unique to each person

  • The hymen tissue doesn’t have a known function

  • Most often the hymen naturally has a hole or holes in it.

  • These holes are big enough for menstrual blood to come out

  • There are some vulvas with so little hymenal tissue that it would appear they don’t have one

  • There are rare cases where the hymen covers the entire vaginal opening requiring surgical intervention

  • The hymen tissue is thin and is naturally stretched with activities like riding a bike, playing sports and inserting a tampon or finger into the vagina.

  • Once stretched, the hymen does not grow back.

  • The hymen is a membrane with relatively few blood vessels, so if torn or stretched, may not bleed significantly.

  • An examination of the hymen is NOT an accurate or reliable “test” of history of sexual activity.
