Mark Parisi of Las Vegas is planning on selling one of his testicles as part of a medical trial in exchange for $35,000.
Mark will donate one of his testicles to a research team and an artificial testicle will be placed inside his body.

The whole ordeal will take about 2 weeks and then we will be a richer man with one less testicle.
Mark however revealed that he constantly takes part in these trials in order to earn extra or save money. He admitted that he often volunteers for clinical trials throughout Nevada, where he is used as a guinea pig by the establishments for many processes.
He also confessed to undergoing medical experiments so he could get free checkups, which can save him around $700.
Mark will be on an upcoming episode of "Extreme Cheapskates" on TLC. He will talk about his testicle-selling journey and other crazy things that he's done to make some extra bank.
