At present, there are not any "local compounds" available that can be applied to prevent STIs, just the "classic" spermicide, which was a "crude inhibitor of fertility", Prof Aitken said.
"Women who use a lot of this stuff, especially commercial sex workers, are significantly more likely to get HIV than women who don't use it ... it just destroys everything around it," he said.
