I would rather get this done personally. Their FAQ says they aren't sure if it is reversible, so that is the only thing that would be an issue. They need to find some guys in their 50s who are done having kids and pay them to get this device for 2 - 10 years, and then take it off and see if the sperm come back.
I think there is a plan to keep male birth control off the market. If most of the 14-16 year old boys would get this device, how many more STDs would there be? When they don't have to worry about pregnacy, the condom usage rate would plummet.
