Bill Gates lays down condom challenge

Bill Gates has laid down a challenge in the hope of promoting safe sex practices around the world.

The Microsoft founder announced whomever can come up with the 'perfect condom' will be awarded a grant of $100,000 (£66,000) to develop the concept.

Entitled the Next Generation Condom Challenge, the competition is forming part of the Bill and Melinda Gates Foundation's attempts to tackle global health issues.

It is hoped that these new prophylactics will offer high protection against sexually transmitted infections and unwanted pregnancy, while at the same time not diminishing the pleasure felt by male users.

Stephen Becker, deputy director of the HIV Program at the foundation, said: "The more appealing a condom is for a man to use, the greater likelihood of use there will be."

The proposal submissions deadline has been set at May 7th 2013, with the winner of the grant to be announced in November later this year.
