Answer:
Birth control sponge
Explanation:
The birth control sponge is a contraceptive method classified as a barrier contraceptive because it literally creates a physical barrier between the uterus and sperm.
The birth control sponge is basically a small disc-shaped piece of foam with a cavity and a handle that starts working after it is placed on the cervix. It is made of polyurethane and releases spermicide all the time to keep the uterus protected for up to 24 hours against unplanned pregnancy.
