A vaginal condom is a soft, plastic (non-latex) sleeve with two flexible rings, one on each end. It’s sometimes called a female or internal condom. The closed, inner ring goes inside the vagina. The outer ring stays outside the vagina to cover the genitals. The vaginal condom is used for vaginal sex. It decreases the risk of pregnancy and STIs and HIV by stopping semen and body fluid from passing between partners.
With typical use (not following exact directions) a vaginal condom is 79% effective. With perfect use the vaginal condom is 95% effective at preventing pregnancy. Vaginal condoms give good protection from STIs and HIV.
Never use a vaginal and a male condom at the same time, as it increases the risk of both breaking. Condoms used with another method of birth control (pill, patch, injection, ring, IUD) give the best protection from pregnancy, STIs and HIV. Never reuse a condom.
