VCF, Foam, Jelly, and Inserts
Besides being applied directly to barrier methods of contraception, spermacide also comes in other highly concentrated forms. People who are allergic to spermacide should not use these products. It is important to remember that these are only methods of contraception and should not be considered safer sex. Besides abstinence, the most effective method of contraception is the use of a barrier method and one of the following back-up methods. While most of these methods should be used ten minutes before intercourse, other forms of foreplay may be performed during this time.
Vaginal Contraceptive Film, or VCF, is a high concentration of spermacide in the form of one thin square inch of film. To use a VCF, fold it in half one lengthwise and in half widthwise. Fold down the corners since they may be slightly sharp, and insert the VCF in the vagina as far as possible. Wait ten minutes for the film to dissolve in the vagina before intercourse. If the VCF starts irritating the user, remove immediately.
Contraceptive foams, such as Koromex and Delfen, contain a high concentration of spermacide. To use it, first thoroughly shake the can. Place the applicator on the tip of the nozzle and push tilt the nozzle gently. The foam will quickly fill the applicator. Insert the applicator in the vagina and push the foam into the vagina. For best results, wait ten minutes before beginning intercourse. If an hour has passed since the last application, it is best to reapply.
Spermacidal jelly, sold under the brand name Gynol II, is another form of concentrated spermacide. It may be applied to condoms, diaphragms, and cervical caps for added contraceptive protection. While it is effective to apply spermacidal jelly to condoms which are not already treated with spermacide, it is better to simply use condoms with spermacidal lubricant already applied to the condom.
Contraceptive inserts, sold under the brand name Concepterol, are another method of using highly contrated spermacide for contraception. Each insert is approximately a half inch long and less than a quarter inch in diameter. The insert should be inserted as far up in the vagina as possible. Wait ten minutes after insertion before intercourse to assure that the insert has dissolved.
