Editing Contraceptive sponge (section)

== Use ==
The sponges are inserted [[vagina]]lly prior to intercourse and must be placed over the cervix to be effective. Sponges provide no protection from [[sexually transmitted infection]]s.  Sponges can provide contraception for multiple acts of intercourse over a 24-hour period, but cannot be reused beyond that time or once removed.<ref>{{cite web |title=Today Sponge Vaginal Contraceptive Sponge Consumer Information Leaflet |url=http://todaysponge.com/pdf/todaysponge-pi2.pdf |publisher=Mayer Laboratories, Inc. |access-date=3 March 2019 |archive-date=26 February 2023 |archive-url=https://web.archive.org/web/20230226114101/http://www.todaysponge.com/pdf/todaysponge-pi2.pdf |url-status=dead }}</ref>

Sponges are a physical barrier, trapping sperm and preventing their passage through the cervix into the reproductive system. The [[spermicide]] is an important component of pregnancy prevention.
