The causes of BV
) are not understood. It can develop when something -- for example, sexual contact -- disrupts the balance between the "good" bacteria that protect the vagina from infection and the harmful bacteria that don't.
Is Sexual Contact a BV Cause?
It is not clear what role sexual activity plays in the development of BV, but the condition is more common among women who have had vaginal sex. However, sexual contact is not always a BV cause.
We do know that certain things can upset the normal balance of bacteria in the vagina and put you at greater risk for BV. Some of these things include:
- Having a new sex partner or multiple sex partners
- Using an intrauterine device (IUD) for birth control
- Not using a condom during sex.
We also know that you do not get BV from toilet seats, bedding, swimming pools, or from touching objects around you.
