The contraceptive sponge is a vaginal barrier method that prevents pregnancy by keeping sperm from fertilizing an egg that your ovaries produce each month. The disposable sponge containing spermicidal is placed at the cervix and absorbs and destroys sperm. The sponges are inserted vaginally prior to intercourse and must be placed over the cervix to be effective. Women who are allergic to nonoxynol-9 should not use any vaginal barrier method that contains this spermicide.
After it is placed in the vagina, the sponge prevents pregnancy by releasing a spermicide, it works by killing or paralyzing sperm that comes into the vagina. The sponge is soft and once inserted properly you or your partner should not be able to feel it. If it feels uncomfortable, it may not be inserted in the right way. If this happens, slowly and gently reposition the sponge deep into your vagina until it covers your cervix.
The contraceptive sponge has a few risks, including tearing, yeast infection, and allergic reactions from the spermicide. Contraceptive Sponges provide no protection from Sexually Transmitted Diseases (STDs). To lessen the risk of getting an STD, a condom should always be used.
Advantages of the contraceptive sponge
Because you may insert the sponge when your sex partner is not present, they offer a good measure of contraceptive privacy. Sponges are easy to use, relatively inexpensive, and available without prescription. The sponge offers continuous protection for up to 24 hours after insertion, no matter how many times you have sex.
Disadvantages of the contraceptive sponge
For each act of sex, you need a fresh, unopened sponge and clean water. If left within the vagina for more than 30 hours, the sponge slightly increases your risk for a very serious infection called toxic shock syndrome. Don't leave your sponge in for more than 30 hours. Some women find it difficult to place the sponge correctly. Some women have difficulty removing the sponge. Sponges must be stored in a clean, cool, dark place-not in the glove compartment of a car or in a purse. The sponge may accidentally be placed onto the cervix improperly or may slip out of place during sex. The sponge must be inserted into the vagina and up against the cervix prior to the penis entering the vagina. You need to wash your hands with soap and water before you insert the sponge.
