ABSTRACT
Vegetable-and oil-based lubricants, and the bases for many prescribable vaginal products, can seriously damage and lead to rupture of rubber: baby oil destroys up to 95% of a condom’s strength within 15 minutes. Beware ad hoc use of, or contamination by substances from the kitchen or bathroom cupboard! Water-based products such as KY jelly, and also glycerine and silicone lubricants, are not suspect. The Box on page 133 lists some common vaginal preparations which should be regarded as unsafe to use with rubber condoms and diaphragms, and there may be others.
