Hello,

Thanks for posting your query.
Vaginal lacerations are most commonly caused during intercourse or during child birth. Forceful penetration of penis causes serious lacerations resulting in heavy bleeding.
Penetration is very unlikely to be accidental. It is always a planned incident.
Accidents causing pelvic fractures may lead to vaginal lacerations.
Vaginal lacerations can be accidental due to bicycle seat injuries, horse riding injuries, etc.
In a small child, accidental vaginal lacerations can occur by inserting a foreign body in vagina unknowingly.

Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.

Wishing you good health.

Regards.
