Apparently they are based on American research, showing how a gel and go from liquid to solid based on acidity/alkalinity and temperature, whenever pre-ejaculate/semen/sperm is present in a woman, and form a barrier to block it and dispose of it. And the silver acts as an anti-bacteria/viral to prevent STI's.
