for preventing vaginal acquisition of HIV infection by women from men (Cochrane Review).
In 2000, results of a trial involving female sex workers in South Africa, Benin, Cote d'Ivoire and Thailand showed that nonoxynol-9
is ineffective for prevention of HIV transmission (source: Van Damme L et al.
The poster reemphasized the risk for transmission of HIV associated with anal intercourse; encouraged the use of latex condoms and water-based lubricants, including those with nonoxynol-9
spermicide; and discouraged anal intercourse without condoms, rectal douching before and after anal intercourse, and the use of "natural membrane" condoms and petroleum-based lubricants.
But some good news: At the recent ASM meeting came confirmation of last year's reports that nonoxynol-9
, the active ingredient in most spermicides and in a commercially available contraceptive sponge, has an anti-chlamydial effect in mouse cells in vitro.
Point out that recent studies have shown that microbicides such as nonoxynol-9
may increase HIV transmission since they often irritate the epithelium.
Initially, expectations for existing over-the-counter spermicides containing nonoxynol-9
Each Carter brand, Trojan, Mentor, Class Act and Naturalamb features at least one variety with Nonoxynol-9
spermicidal lubricant for extra protection against pregnancy.
Planned Parenthood's decision is a result of recent research from the World Health Organization and the Centers for Disease Control and Prevention that showed that nonoxynol-9
offers no protection against sexually transmitted infections.
Evidence is accumulating that nonoxynol-9
is ineffective as a vaginal microbicide.
