Background Information

The modern sponge combines both a barrier as well as spermicide in order to prevent conception. The sponge is concave and shaped like a dimple in order to fit directly over the cervix. The contraceptive sponge lasts for around 24 hours, and it should not be removed until 6 hours after the last time of intercourse.

How to Use

• First, get the sponge a little bit wet and squeeze the water out (do not make it completely dry).
• With the string hanging below, fold the sides of the sponge upward and push the sponge as deep as possible into the vagina.
• Be careful when inserting the sponge to make sure it covers the cervix.
• For removal, find the string and pull it out very carefully.
• Do not flush it down the toilet, but throw away in a trashcan or other form of disposal.

Advantages

• Is accessible over the counter
• Does not need to be fitted
• Lasts for up to 24 hours, allowing individuals to have sex multiple times
• Single use so it does not require cleaning like the diaphragm or cervical cap
• Can be disposed of easily

Disadvantages

• Not as effective as a lot of other methods
• Spermicide can cause allergies or rashes
• Does not provide a means to protect against STIs
• Some studies have shown that it increases the chance of getting HIV

Efficacy

If a woman has never given birth, the chances of the sponge failing are 16% for normal use and 9% if it is used perfectly. If a woman has given birth before, the chances slightly increase to 32% for normal use and to 20% for perfect use.

Availability

The sponge can be found at drugstores or supermarkets for around $1.50 each.
