What is Spermicide?

A spermicide kills or disables sperm so that it cannot cause pregnancy. Spermicides come in many different forms: foam, jelly, cream, film, and suppositories. Most use the chemical nonoxynol-9 against sperm. Spermicides provide lubrication and can be used with other methods of birth control.  They are most effective when used consistently and correctly with a barrier method of birth control, like a condom. Spermicides are 71-82% effective as birth control. Used alone, spermicide does not protect against HIV/AIDS.

Use
Spermicide can be used alone or with other birth control methods to reduce the risk of pregnancy. The lubrication it provides can increase pleasure. Insert your spermicide within a half hour before intercourse. Add more spermicide for repeated intercourse. Leave your spermicide in your vagina for 8 hours after the last act of intercourse and do not douche for 8 hours. Douching weakens spermicide. It is available in most drug stores and does not require a prescription. 

Foam
Foam comes in a can and is the consistency of shaving cream. To use it, shake the can well. Place the applicator on the top of the can and press down or to the side, depending on the package directions. The plunger will rise as the applicator fills. Insert the applicator about two or three inches into your vagina and press the plunger to deposit the foam over your cervix. As you withdraw the applicator, be sure not to pull back on the plunger. This will suck some foam back into the applicator. It is effective immediately.

Creams and Jellies
Creams are opaque and jellies are clear. They can be inserted into the vagina with an applicator and/or rubbed over the penis. Cream or jelly is typically used with a diaphragm or cervical cap. It can also be used with condoms and is effective immediately.

Vaginal Contraceptive Film (VCF)
VCF comes in thin squares that dissolve over the cervix. To use it, fold the film in half and then place it on the tip of a finger. Insert your finger into your vagina and put the VCF over your cervix. A dry finger and quick insertion will help the VCF stay in place and not stick to your finger. It may take about 15 minutes for the VCF to melt and become effective.

Suppositories
Suppositories are capsules that dissolve in the vagina. They are inserted into the vagina like a tampon and pushed up to the cervix. It takes about twenty minutes for a suppository to become effective.

Sponges
The sponge is a both a chemical and a physical barrier, and is 80 - 91% effective. It is a small, soft, bowl-shaped piece of synthetic sponge with a loop attached. It contains a spermicide, so it both blocks and absorbs sperm and also kills sperm. It is less effective for women who have previously given birth.

To use, moisten with water and insert into the vagina with the dimple side towards the cervix..  It can be inserted up to 12 hours before sex and can be used for multiple acts of intercourse.  It must be left in the vagina for 6 - 8 hours after intercourse. Pull the loop to remove the sponge.

The sponge is not currently availble in the United States, but can be found in other countries and/or purchased through online ordering.

Your Health
The vagina absorbs little spermicide. If you become pregnant while using spermicide, the pregnancy will not be affected.

Side Effects
You or your partner may be allergic to materials in spermicide. This can cause genital irritation, rash, genital dryness or itchiness. If this happens and your spermicide has nonoxynol-9, try a spermicide without this chemical. Research also indicates that spermicide increases the risk of HIV for sex workers when used frequently.

Disadvantages

• Does not protect against HIV/AIDS.

• Can be messy.
• Can have a bad taste during oral sex.
• Possible genital irritation.
• When used frequently spermicides may irritate the vagina making it easier to catch HIV/STI

Your Cervix
The cervix is the opening to the uterus where menstrual blood, babies, and sperm pass. It is also the opening through which abortions are performed. Spermicide and barrier methods of birth control, like the diaphragm, female condom, and cervical cap, work by covering the cervix and preventing sperm from entering the uterus. Hormonal methods of birth control, including oral contraceptives and Depo Provera, affect the mucus around the cervix and make the opening more resistant to sperm.

Women's bodies also naturally produce hormones that change the cervix during a menstrual cycle. You can learn more about your cervix using a speculum to perform a self-exam. For instructions and a speculum, ask your clinician or visit FWHC.org.
