Canadian Study Warns of Potential CJD Risk from Fertility Drugs
A Canadian-led research team warns there may be an underappreciated risk to fertility drugs: The treatments most frequently prescribed have the potential to spread Creutzfeldt-Jakob (also known as Mad Cow) disease. The controversial research, which was funded in part by the federal government, tested dozens of samples of the most commonly available fertility drugs from around the world and found that all those with pregnancy-enhancing hormones extracted from human urine contained prion proteins. The finding of the protein as a contaminant in these products indicates that infectious prions wouldn’t be excluded from the manufacturing process if a urine donor was incubating the brain-wasting disease.
