The hymen is a ring-like form of tissue that represents the opening to the vagina. Sometimes girls are born with conditions that affect the hymen, including a membrane covering the hymen, a membrane covering with a very small opening, or a band of extra tissue in the area of a normal hymen. These conditions are present at birth and the cause is unknown.
