Female condoms, sometimes called internal condoms, are small nitrile (soft plastic) pouches that prevent semen from reaching an egg. They are similar to regular condoms except they are placed inside the vagina instead of over the penis.
Female condoms prevent semen from entering the vagina and reaching an egg. They can be worn during vaginal or anal sex.
Female condoms are 95% effective at preventing pregnancy when used properly. However, do NOT use a female condom and regular condom at the same time. They are not designed to work together and will actually increase the likelihood of tears and leaks.
Female condoms can be more difficult to find than regular condoms. The only FDA approved brand available in the U.S. is the FC2 Female Condom®. You can buy them online or at many Planned Parenthood health centers.
