When Lisa Rentz decided she'd had enough of birth control pills, she walked into her local drug store and picked up something different: a vaginal contraceptive film that contains the spermicide nonoxynol-9, or n-9...For some women, like Rentz, who have been in a monogamous relationship for years with an HIV-negative partner, there is virtually no risk at all, according to Mayo Clinic OB-GYN Petra Casey. Women simply need to be well-informed so they can choose a birth-control method that's right for them.
