Contraceptive Sponge
Online Birth Control Education

The contraceptive sponge is a small, pillow-shaped spermicide containing polyurethane sponge, shaped like a concave dimple, with a cotton loop, that fits over the cervix. The primary mechanism of providing contraception is the introduction of spermicide into the vagina, consistently released over a 24-hour wear time. The sponge can be used for several acts of intercourse over the 24-hour period without needing any additional spermicide. The sponge also acts as a barrier, preventing sperm from entering through the cervix, into the uterus and must remain in place at least 6 hours after the last act of intercourse.

Most partners cannot feel the sponge during intercourse. The sponge is a one-size fits all item and a one-time insertion only item. It should not be removed and reinserted after intercourse.

How to use the sponge:

Wet it with tap water and squeeze several times until it becomes sudsy. Do not squeeze the sponge dry.
Fold the sides upward with a finger along each side to support it. Be sure the string loop dangles underneath.
Use one or two fingers to push the sponge gently up into the vagina as far as it will go.
Be careful not to push a fingernail through the sponge.
Check the position of the sponge to see that the cervix is covered and the string loop can be felt.
Always wait at least six hours after the last act of intercourse before removing the sponge. Place the finger into the vagina, find the string loop, tug gently on the string and pull out the sponge.
If removal is difficult, relax the vaginal muscles and try again. Dispose of sponge in a waste container; do not flush it down the toilet.
