Other factors associated in the development of BV include douching, tub bathing (particularly with bubble bath), use of over-the-counter intravaginal hygiene products, multiple sexual partners, high frequency of intercourse, the use of an IUD and the presence of other sexually transmitted diseases. [9]  The theory for why these factors contribute to the development of BV is that they disrupt the normal vaginal flora. Some evidence shows that hormonal contraception (both combined estrogen/progestin and progestin only) is protective for the development of BV. Recurrent BV may be attributable to previous colonization of the oral cavity or anus with BV-associated bacteria. [10]
