From the video description:
Testicular Cancer New Zealand unveils its distinctly low-tech ‘machine’ that tests men’s testicles for irregularities and lumps. It launched at the Big Boys Toys event in Auckland and involves a urologist or GP reaching through a small opening to check the occupant’s testicles in the privacy of a small booth. On top of performing physical checks, the primary aim of the device is to educate men on the importance of self-checking every month. Testicular cancer is the most common cancer affecting New Zealand men aged between 15 and 39 and is one of the most treatable cancers if detected early, with a survival rate of 95%.
It didn’t seem that anonymous, did it?
