What are internal condoms?

Internal condoms are a thin barrier that is placed in the vagina before to penetrative intercourse. They catch sperm and are made of polyurethane (similar to the material of medical gloves). They are twice as strong as the latex in condoms.

Internal condoms are protective against pregnancy; the risk of pregnancy is 21 per 100 women with typical use, but can be as good as 5 per 100 women if used perfectly.
