Spermicide Contraception is one of the commonly used methods of contraception. Spermicides are easy to use and cost effective. However, they do not prevent against STDs and are not 100% reliable.
Spermicidal contraception has been around for thousands of years. Therefore, they are the oldest method of contraception. Spermicides are now available as cream, jelly, foam, suppositories, sponge and film. Depending upon the choice of spermicide used, each use costs about $.50 to $1.50
How Spermicides Work as a Contraceptive. Spermicides act as a vaginal barrier and hinder the sperm from fertilizing the egg, because the spermicidal chemical either kills or paralyzes the sperm. They are applied deep into the vagina of a woman near the cervix every time there is sexual intercourse. They can be used alone, but are more effective when used with other forms of contraceptives such as a condom.
It is advisable to use spermicides about fifteen minutes prior to intercourse so that there is enough time to dissolve and spread. Spermicides are effective only about an hour after application.
How to Use Spermicide. Spermicide in an aerosoal form, also called contraceptive foam is inserted deep into the vagina with a small applicator. Gels and creams are also used similarly.
Vaginal suppositories are oval shaped and are placed inside the vagina. They produce spermicidal foam in about ten to fifteen minutes of application. Vaginal contraceptive films are flat wax-paper like tissues that contain spermicide, nonoxynol-9. Films are put on a dry finger tip and inserted in the vagina. Care must be taken that the hands and the applicator are sanitized before use.
Advantages and Disadvantages of Spermicidal Contraceptive. Spermicide is easily available and cheap to use. The application is fairly easy. But the list of disadvantages is long.
Spermicides contain a chemical called nonoxynol-9. Some women are allergic to it. Spermicides do not prevent against STDs such as HIV. If a woman uses a spermicide, following all instructions correctly every time before having sex, as there is a fifteen percent chance of a pregnancy. If the spermicide is not used correctly, there is a 26 percent chance of pregnancy.
Some women experience irritation in and around the vagina and can get urinary tract infection. Rashes and soreness around the vagina and smelly discharge are other common problems associated with spermicidal contraceptives.
