	'''Contraceptive sponge''' is a type of [[birth control]] method that is soft, round, and about two inches in diameter.

	== ~~Mechanism of Action~~ ==		== Overview ==
			The '''contraceptive sponge''' is a small, round device made from soft, squishy plastic foam. It is used as a [[barrier method]] of [[contraception]] to prevent [[pregnancy]]. The sponge is inserted into the [[vagina]] before [[sexual intercourse]] and works by covering the [[cervix]] to block [[sperm]] from entering the [[uterus]].

	The contraceptive sponge ~~works in two ways. First, the sponge releases~~ spermicide, ~~which kills sperm and prevents them from fertilizing an~~ [[~~egg~~]]. ~~Second~~, the ~~sponge acts as~~ a barrier~~, blocking the~~ sperm from reaching the egg.		[[File:Éponge_spermicide.jpg\|thumb\|right\|A contraceptive sponge]]

			== Composition and Mechanism ==
			The contraceptive sponge is typically made of [[polyurethane]] foam and is infused with a [[spermicide]], usually [[nonoxynol-9]]. The spermicide serves to immobilize and kill sperm, providing an additional layer of protection against pregnancy. The sponge is designed to fit snugly against the cervix, creating a physical barrier that prevents sperm from reaching the egg.

			== Usage ==
			To use the contraceptive sponge, it must be moistened with water to activate the spermicide. The sponge is then folded and inserted into the vagina, ensuring it covers the cervix. It can be inserted up to 24 hours before intercourse and must be left in place for at least 6 hours after the last act of intercourse to ensure effectiveness. However, it should not be left in for more than 30 hours in total.

	== Effectiveness ==		== Effectiveness ==
			The effectiveness of the contraceptive sponge varies depending on whether the user has given birth before. For women who have never given birth, the failure rate is approximately 9% with typical use. For women who have given birth, the failure rate increases to about 20% with typical use. The sponge does not protect against [[sexually transmitted infections]] (STIs).
	The effectiveness of the contraceptive sponge varies depending on whether ~~or not~~ the ~~woman~~ has given birth. For women who have never given birth, the ~~sponge~~ is ~~about 91~~% ~~effective~~. For women who have given birth, the ~~sponge is~~ about 80% ~~effective~~.
