Spermacide

Spermicide gets its name from a sperm-killing chemical that helps prevent unwanted pregnancies. As one of the oldest forms of contraception, spermicide has been around since 1850. Spermicide is inexpensive, easy to apply and can be purchased without a prescription at your local drug store or pharmacy. One dose of spermicide is usually effective for an hour, but will need to be reapplied in the case of repeated intercourse. Once lovemaking is over, the woman must not douche for 6 to 8 hours to make sure that all of the sperm are killed. Spermicide is best used in conjunction with a condom, diaphragm or cervical cap to ensure the most effective protection.

What to Look for

Spermicide comes in various forms, including gel, foam, suppository, film or cream. As a cream or jelly, spermicide is applied to a condom, diaphragm or cervical cap, or it can be inserted directly into the vagina with a specially made applicator. Foam spermicides can also be inserted into the vagina with an applicator. A less messy application is to use spermicidal film, inserting it directly into the vagina where it will then dissolve. Creams and jellies provide additional lubrication, which is not the case with jellies, foams, film or suppositories, so it is best to decide what is right for when you shop for the correct spermicide. Make sure you apply the spermicide according to directions. Using spermicide in conjunction with other methods of birth control is highly advised to help to increase the chances for effective contraception.

Common Pitfalls

Follow instructions carefully, as some spermicidal products require a waiting period of 10 minutes after insertion before having sex in order to do their job. Some condoms are made with nonoxynol-9, the primary ingredient in spermicides. It is not advised to use treated condoms if you are having anal sex, as some studies claim that they can increase the potential for contracting sexually transmitted diseases (STDs). Using a spermicide can cause urinary tract and yeast infections in some women. In addition, it has been reported that spermicides can kill the good bacteria needed to combat the proliferation of STDs. If you or your partner feel discomfort or have any adverse reactions after using spermicide, make sure you see your healthcare provider for a complete analysis.
