Spermicides

What are vaginal spermicides?

Vaginal spermicides typically come in three forms: foams, jellies and creams. Spermicides are best when used with a condom, otherwise they are a relatively ineffective method of birth control and do not protect against the transmission of STDs. These chemicals essentially attempt to kill the sperm before it can enter the cervix.

Many condoms, such as the Lifestyles Spermicidally Lubricated line include spermicide. In addition to using these, you can get lubricants, such as ID Plus which contain Nonoxynol-9.

What is the effectiveness of using vaginal spermicides?

Jelly and cream spermicides should be used with another form of birth control because they are not reliable methods when used by themselves. Foam, if used properly every time, is about 92% effective. Unfortunately, many people have trouble using foam correctly each time they have sex. Some users may not fill the applicator fully, others may forget to shake the can. The effectiveness for the typical user of foam is about 80% or less.

How are vaginal spermicides used?

Creams or jellies are often used with another form of birth control. A woman may apply spermicidal cream or jelly to the inside of her cervical cap or diaphragm. Creams, jellies and foams normally are available with the applicator included. For creams or jellies simply screw the applicator onto the tube and fill it. Filling a foam applicator is a similar process. Then insert the applicator and push the plunger down. (Remember you are attempting to cover the cervix.) Always follow the instructions of your physician or family planning center.

Practical concerns when using vaginal spermicides

If you are using spermicides there are a few drawbacks which you may wish to consider. Vaginal spermicides are often very inconvenient.

Drawbacks Include:

• must be inserted less than 20 minutes before intercourse.
• a woman must carry spermicide and applicator with her whenever there's a possibility of having sex.
• chemical taste, not ideal for oral sex.
• do not provide best protection against STDs.
• must be used and stored correctly.
• lubrication provided is sometimes unpleasant.

If a woman experiences an allergic reaction to the spermicide then she may develop a rash or itchiness; at which point the use of that spermicide should be discontinued.
