Definition - What does Contraceptive Foam mean?
Contraceptive foam is a form of barrier method birth control. The foam contains spermicide, which kills sperm cells before they enter the uterus. Contraceptive foams function similar to jellies, and dissolve in the vagina.
Kinkly explains Contraceptive Foam
Contraceptive foams are easy-to-use and do not need to be removed because the foam dissolves and disappears into the vagina. It is recommended that contraceptive foam be used in conjunction with other birth control methods such as condoms. Contraceptive foam should be applied prior to having sex. The foam is effective immediately, but only lasts about a half an hour, so it needs to be reapplied if the condom breaks.
