A new condom called 'Viagra in a Condom' promises to improve a man's erection, increase his stamina and even boost his penis size.

Zanifil is based on the chemical nitroglycerin which is used to treat chest pain and heart failure. It relaxes the muscles in the vessel walls, widening them and increasing blood flow.
The company reported that in comparison trials with standard condoms, a significant proportion of both men and women also felt that CSD500 increased the penis size and a significant proportion of women reported a longer lasting sexual experience with CSD500.
The condom has acquired a CE mark in August itself and can be sold over-the-counter in Europe.
The manufacturers hope the product would encourage men to use protection and help curb the spread of sexually transmitted diseases.
