This new gel will be tested by seeing if the rate of infection is LOWER in the test group vs the control group.

Needless to say 40 women means nothing in statistical analysis, especially in HIV case, which is still a quite rare disease.... 40 women who are not infected with HIV now, won't get infected in a year from now, or most likely ever. 40,000 women would be probably enough, assuming the research is conducted as you claim.
