Durex's new CSD 500 should be available in Europe in January 2012.

Even though it is commonly known as the 'Viagra condom', the CSD 500 has nothing to do with sildenafil. It contains a gel called zanifil that increases blood flow to the penis and improves erections.

More on this:

'CSD500, our Condom Safety Device is a condom developed for use by healthy men. The product incorporates an erectogenic compound to help men maintain a firmer erection during intercourse whilst wearing a condom. The gel is to be licensed under the trademarked brand name of ZanifilŪ.

By applying the CSD500 condom, a pharmacological dose contained within the teat of the condom will be delivered to the penis. This has been clinically proven to increase local blood flow within the penis which in turn leads to increased firmness, increased penile size and longer duration of an erection.'
