OK first...there is no known program that will trade you $35,000 for one human testicle (that I know of)…however, in 2013, The Vancouver Sun did run an article about a Las Vegas man doing a one time medical experiment where they chopped out one of his balls and replaced it with a prosthesis one.
In the end, he didn’t go through with the procedure, low testosterone. But he did sign up for a testerone replacement experiment, and that paid him $500 a month! Good for that guy.
That said, if you could get $35,000 for one of your testicles, would you? Hmmm, let me check with my wife first.
