Sydney: In a first such awareness campaign about testicular cancer, an Australian advertising agency network and an adult film studio have inserted a public health message (with demonstration) in a newly-launched porn film.

In the film titled ‘Game of Balls’, porn star Eva Lovia stops mid-action and speaks directly to the viewer, demonstrating how to check for testicular cancer, using her co-star as a prop, CampaignAsia.com reported.

She then points to an onscreen URL playwithyourself.org where men can learn more about testicular cancer and get help.

The ad agency M&C Saatchi in Sydney worked with leading porn movie studio Digital Playground and the non-profit Blue Ball Foundation to do this experiment with ‘Game of Balls,’ an X-rated parody of the movie ‘Game of Thrones.’

The porn video was launched on www.digitalplayground.com, one of the most visited adult video sharing sites among Australian men.

So far, nearly 200,000 people have visited the site and total film views have crossed 1.5 million.

‘We are overwhelmed with the amount of feedback we have been getting, from emails to Facebook messages to phone calls from all over the world,’ Blue Balls founder Jamie Morgan was quoted as saying.
