The membrane covering the vaginal canal is referred to as the hymen and signifies virginity in many cultures. While penetrative sex is generally the main reason why the hymen tears, there are a number of other factors that could lead to it being incomplete.
In some instances, the hymen may not have developed correctly but in other cases, trauma, tampons and exercise can also cause it to tear.
Women choose to have their hymen repaired for different reasons, including cultural, religious and social. Whatever the reason, hymenoplasty can be used to repair and reconstruct a torn hymen to restore the appearance of virginity.
