SPERMICIDE
Spermicide is a chemical that kills sperm. It is offered in various forms. The spermicide available in the United States is Nonoxynol-9. Spermicide is placed in the vagina before sexual intercourse. Many spermicides require that it be placed at least 15 minutes, but no more than an hour, before intercourse. Spermicide is best used along with other birth control methods, like condoms, to increase their effectiveness.
How effective is it?
Depending on how it is used, spermicide is about 74-94% effective in preventing pregnancy.
What are the advantages of spermicide?
What are the disadvantages of spermicide?
What types of spermicide can I get?
- Vaginal Contraceptive Film (VCF): VCF is an approximately 2 inch square, thin, clear, flexible film, which is placed high in the vagina where it dissolves. Of the spermicides available in the U.S., it has the highest percentage (28%) of Nonoxynol-9. For more information, go to the manufacturer's website at: http://www.apothecus.com/film.html
- Suppositories: Suppositories are almond-shaped tablets that are placed in the vagina and dissolve. Some of the common brands of suppositories are: Encare, Semicid, Conceptrol, and Koromex.
- Gel/Jelly: Contraceptive gel or jelly requires an applicator to place a measured amount of spermicide in the vagina. It is usually clear and thick. Some gels/jellies are only indicated for use with diaphragms or cervical caps.
- Foam: Contraceptive foam is also placed in the vagina by using an applicator.
Can I just use a lubrication that contains spermicide?
Most lubricants do not contain a sufficient percentage of spermicide to significantly increase pregnancy prevention.
Are spermicidal condoms more effective?
Spermicidal condoms do not appear to be any more effective in preventing pregnancy than condoms without spermicide. To increase the effectiveness of condoms, use them with a regular spermicide such as film, suppositories, foam or jelly.
How much does spermicide cost?
Spermicide kits cost about $8-$15 in drugstores and clinics. Refills cost $4-$8.
