Lines: 77 SPERMICIDES CONTAINING NONOXYNOL-9 [Source: Clark L. Taylor, Ph.D., Ed.D. Institute for the Advanced Study of Human Sexuality, San Francisco, CA, 415-928-1133 Call them for a copy of their report "Condom Use, AIDS Prevention, and Increased Sexual Enjoyment" If you live in the San Francisco area, call for a reservation to one of their workshops on "Eroticizing Safe Sex" (Excellent!) Another good source is the SF AIDS Foundation Hotline, 800-FOR-AIDS] Nonoxynol-9 is a mild detergent used in spermicides and various other "feminine hygiene" products to prevent pregnancy and V.D. It works by bursting the outer protein cap of sperm and various disease organisms. In laboratory tests, this detergent quickly and effectively kills herpes, gonorrhea, syphilis, CMV, yeast, trichomonas, and amoebas. Most recently, it also has been found to kill AIDS virus easily in the test tube. This is promising news, however nonoxynol-9 is considerably more effective under laboratory conditions than in actual sexual use because: a.) The inert ingredients in spermicides -- foams, gels, and creams -- do not always spread evenly or form a sufficient chemical barrier for nonoxynol-9 to kill pathogens before they can reach uninfected tissue. b.) People often use spermicides incorrectly and only when they "think" a partner is infected. c.) People abandon condoms instead of using nonoxynol-9 and condoms together. It is very tempting to use nonoxynol-9 as a layer of prevention against AIDS while engaging in oral sex and anal intercourse. But make sure spermicides don't irritate your skin, your mouth, or your rectum. When in doubt, check with your doctor. And to be sure the doctor's really up on the subject, be well informed yourself. (See "Reading Up On Condoms and Spermicides.") Studies show that: 1. Nonoxynol-9 has had a very good safety record for 35 years and has been used by Gays in spermicides and a couple of lubricants for anal intercourse over the last 7 years without any reports of problems. A preliminary study by Bruce Voeller, Ph.D indicates that the intestines of 50 spermicide anal users were healthy. Animal research which studied nonoxynol-9 excretion through the intestines also showed no abnormalities. However, spermicides have only been tested for safe human use on the skin or in the vagina. The FDA noted in 1980 that spermicides are regularly swollowed during oral sex. Because of their extremely low toxicity and because nonoxynol-9 is used as a wetting agent in foods, the FDA deemed spermicides safe when eaten in small quantities. 2. Spermicides provide very important protection from common STD transmission if used properly and every time a person has intercourse (remember, the testing on spermicides and AIDS s incomplete). However, the effectiveness drops quickly from 90%+ to 70% or less effectiveness when not used exactly as instructed on the label. 3. Spermicides and condoms used together and correctly result in much greater disease prevention than either technique alone. 4. At this point not enough is known about the effect of nonoxynol-9 on human intestines (especially during sex) or about AIDS virus to recommend spermicides totally without reservation for anal sex OR to recommend strongly against them! But they are certainly recommended for vaginal intercourse as a layer of AIDS prevention (provided a person is not allergic to them -- remember that changing brands usually takes care of this problem).
