Spermicidal Foam

Description
Spermicidal foam is a non-prescription contraceptive that is easy to use, easy to obtain, and moderately effective in preventing pregnancy. Spermicidal foam has the consistency of shaving cream and contains spermicide which is a chemical that kills sperm. The foam is placed into the vagina. Spermicidal foam helps prevent pregnancy in two ways: the foam forms a physical barrier to the entry of sperm into the cervix, and the spermicide immobilizes and kills the sperm.

Instructions
Some brands of spermicidal foam are sold in pre-measured, ready-to-use applicators. If the foam is sold in a separate container, shake the can of foam well before using (about 20 times). Follow the package instructions for filling the applicator. Gently insert the applicator completely into the vagina, then withdraw it about one-half inch. Depress the plunger fully, then withdraw it. Two full applicators of foam should be inserted no more than 1/2 hour before each act of intercourse. If a condom is used in addition to the foam, only one full applicator of foam is necessary.

After intercourse, a mini-pad or a panty-liner may be used if the foam drips out. If you decide to douche, wait at least eight hours after intercourse before doing so.

Wash the applicator with soap and warm water. Store the container of foam away from heat. Keep a spare container of foam available, since with most brands there is no way to tell how much is left in the container. Do not use foam that has been stored for more than a year.

Advantages
Spermicidal foam is inexpensive and can be purchased at any drugstore or family planning clinic.

Foam is a moderately effective contraceptive method when used alone. When it is used in conjunction with condoms, its effectiveness is increased. Foam can slightly reduce the chance of contracting common vaginal infections; however, it should not be considered an effective deterrent to preventing the transmission of sexually transmitted diseases.

Disdvantages
Some people may find that a particular brand of foam causes burning or irritation. This can usually be remedied by switching brands.

Foam has an unpleasant taste and may inhibit oral sex if inserted beforehand. Some people object to the use of spermicidal foam because sexual activity must be interrupted to use the foam. Failure to use foam consistently and correctly can lead to method failure.

Effectiveness
Theoretically, foam is 94% effective when used correctly with each act of intercourse. The actual use effectiveness is 78%. This takes into account nonuse, misuse, and mechanical failure.

Effectiveness can be increased if condoms are used in conjunction with spermicidal foam.

Other forms of vaginal spermicides (including creams, jellies, suppositories and film) are considered similar in effectiveness as contraceptive foam, although foam appears to be the easiest to use.
