Re: hymenoplasty
What might damage the hymen
The hymen is not normally damaged by playing sports, using tampons, pelvic examinations or even straddle injuries.[21]](Hymen - Wikipedia)
Once a girl reaches puberty, the hymen tends to become quite elastic. It is not possible to determine whether a woman uses tampons or not by examining her hymen. Sexual intercourse is one of the most common ways to damage the hymen, although only 43% of women report bleeding the first time they had sex; which means that in the other 57% of women the hymen likely stretched enough that it didn’t tear.[21]](Hymen - Wikipedia)
It is rare to damage the hymen through accidental injury, such as falling on the top tube of a bicycle. Although such an accident may cause bleeding, this is usually due to damage to surrounding tissues such as the labia.[22]](Hymen - Wikipedia) It is unlikely that an accident would damage the hymen without injuring any other part of the vulva. Therefore, damage to the hymen alone, described as an accident, would be seen as a strong indicator of sexual assault.
