This could mean safe, new materials to "preserve or enhance sensation." Most condoms are made of latex.
Other important features include making male and female condoms easier to use (perhaps with better packaging or easy-to-use designs) and attributes that "address and overcome cultural barriers."
Condom designers will have to work hard to get their grant money. Plans need to have a concept that can be thoroughly tested and validated. Test data will need to give clear results before moving on to further testing.
About 15 billion condoms are made every year and used by about 750 million people.
Female condoms, put inside the vagina before sex, are 95% effective if used correctly.
Condom use has been traced back to ancient Egypt and even cave paintings in France.
