Researchers have developed a female condom which they claim can protect against pregnancy and sexually transmitted diseases such as HIV by dissolving inside the body and releasing chemicals.

Besides blocking the sperm, the condom could time-release a potent mix of anti-HIV drugs and hormonal contraceptives, the 'Daily Mail' reported.

Experts claim the 'discreet protection' can safeguard people from HIV and unwanted pregnancy by 'melting' inside the body.

Researchers at the University of Washington (UW) developed the condom from tiny microfibres through a method called 'electrospinning'.

The cloth-like fibres can be woven from medicine into extremely thin 'webs'. They are then designed to dissolve after use, either within minutes or over several days.
