Background. Latex condoms are used as contraceptives and as preventives aga
inst sexually transmitted diseases. Latex rapidly and significantly deterio
rates when exposed to pure mineral oil and vegetable oil. We wanted to dete
rmine if short exposures to readily available over-the-counter (OTC) intrav
aginal preparations could affect latex condom integrity.
Methods. We compared the mean burst time of test latex condoms, which had 5
-minute exposure to various OTC vaginal products, with the mean burst time
of control (unexposed) condoms during pressurized air inflation.
Results. Baby oil reduced the mean burst time from nearly a minute to just
over 11 seconds. One intravaginal moisturizer and two intravaginal antifung
al preparations also adversely affected latex condom integrity. Products th
at weakened latex condoms contained either mineral oil or vegetable oil.
Conclusions. Women who rely on latex condoms should exercise caution if usi
ng OTC vaginal products containing either mineral oil or vegetable oil. Suc
h products apparently can decrease condom strength and potentially jeopardi
ze efficacy.
