The diaphragm is a dome-shaped rubber disk that you insert into the vagina before having intercourse. The diaphragm must be fitted by a health professional, but of course not every time you use it! It is available by prescription only. The diaphragm must be left in place for at least six hours but not longer than 24 hours after intercourse.

Effectiveness: When used with a spermicide, the diaphragm does double duty - it prevents sperm from reaching the uterus while the spermicide cream or gel applied to the diaphragm before insertion kills the sperm. Used properly, the failure rate for the diaphragm is about 4-8% during the first year of use.

Side effects: Sometimes sensitivity to the spermicides or allergies to the latex in the diaphragm may occur. The diaphragm may also increase the risk of urinary tract infections. In addition, toxic shock syndrome may occur if the diaphragm is left in place for more than 24 hours.

 

The sponge is a disposable, disc-shaped polyurethane foam device which covers the cervix, the sponge is designed to absorb and trap sperm. The sponge contains spermicide to kill sperm. It has two slots for easy insertion and removal and is available without a prescription. The sponge comes with spermicide and provides continuous protection for 12 hours

Effectiveness: The typical failure rate for the sponge is around 11%. That number rises in women who have already given birth. When used with a male condom, however, the failure rate for the sponge method is only 2%.

Side effects: Occasionally, allergy to the foam in the sponge, or to the spermicides, can occur.

 

The Lea Contraceptive is a soft pliable cup shaped bowl with a loop for easy insertion and removal. The Lea Contraceptive prevents sperm from entering the cervix. Like the diaphragm and the cap, the Lea contraceptive is inserted into the vagina before intercourse. It is available without a prescription from your pharmacist.

Effectiveness: The Lea contraceptive must be used with a spermicide and left in place for 8-hours to be effective. When used with a spermicide the failure rate for the Lea contraceptive is 8.7%, higher if spermicide is not used.

Side effects: Allergies to silicone or to spermicides can occur.
