Internal condom

Internal condom


    Research shows that with typical use the internal condom is around 79% effective, and the male condom around 87% effective. With perfect use the male condom is 98% effective, slightly more than the internal condom at 95%.

    The internal condom is made of a thin, strong plastic called polyurethane, or a substance called nitrile.
