I have used the sponge off and on again for years and have never experienced vaginal irritation from Nonoxynol 9, the active ingredient. I think sensitivity to this chemical, like any chemical, is an individual issue. However, one must use the sponge in conjunction with a condom to prevent STD transmission. This was the original concern about the spermicide -- that any irritation caused to the vagina/cervix could create exposure to HIV.
