It is supported by the upper portions of the cardinal ligaments and the parametrium.

This is different from male mammals, who usually have a single urethral opening for both urination and reproduction.

The vaginal opening is much larger than the nearby urethral opening, and both are protected by the labia in humans.

Otherwise, being very elastic, it may return to its normal position.

Additionally, the hymen may be lacerated by disease, injury, medical examination, masturbation or physical exercise.
