A "pump party" involves groups of transgendered men getting together to illegally inject silicone in an effort to make their lips, hips, cheeks and buttocks look more feminine and avoid the cost and scrutiny of legitimate medical treatment. Hundreds, perhaps thousands, of transgendered men have attended "pump parties." Participants typically receive silicone injections from an unlicensed, untrained person who is often using non-medical silicone (which has been found in many cases to consist of Industrial-grade silicone, floor products and sealers, and a host of contaminants including motor oil and paraffin). Costs tend to run between $200 and $1,000 per treatment. Black market silicone and contaminants can result in respiratory arrest, blood poisoning, and other complications that have led to multiple cases of injuries and the deaths of three so far.
