Oestrogen to help prevent HIV in men: research

Researchers at Melbourne University believe the female hormone oestrogen could help prevent HIV infections in men.

Scientists have discovered applying oestrogen cream to a penis thickens the foreskin and provides a natural barrier to the spread of infection.

Professor Roger Short told ABC Radio's PM program the treatment could become an easy, cost-effective way to contain the spread of the AIDS virus.

"By applying oestrogen, you create a natural condom - a membrane that the virus can't get through," he said.
