The Scam Impotence Cure
Medical frauds are usually terrifying since the results are almost never good. That most certainly applies to Dr. John Brinkley, who wasn't even a doctor. But he did become famous because, in the 1920s and 1930s, he provided a treatment for impotence when none of the others worked. Sadly, his scam remedy wasn't something as safe as an energizing tonic. In his human patients, the man was stitching goat testicles.
Unbelievably, goat testicles don't make you more sexually active. However, they did make Brinkley a millionaire, and as a result, he launched his own radio station in Mexico. He successfully transplanted the goat testicles and sealed them inside, therefore the procedure "worked." They would eventually be eliminated by the patient's immune system over time as foreign objects. Of course, given the surgery was pointless, it is unlikely that anyone had greater virility. Unsurprisingly, he was also the target of numerous malpractice lawsuits.
