Usually, your hymen has one hole in it. The hole is big enough for blood to exit during menstruation and for tampon use.
But there are other types of hymen, such as:
- Cribriform hymen: Your hymen has multiple small holes instead of one moderate-sized hole.
- Imperforate hymen: Your hymen completely covers the opening to your vagina.
- Microperforate hymen: The membrane almost completely covers the opening to your vagina, with just one small opening.
- Septate hymen: The membrane has an extra piece of tissue in the middle, creating two small and separate openings to your vagina.
