The Brinkley goat-gland operation was the American, mass-market form of interwar gland-transplant rejuvenation. Where Voronoff offered chimpanzee xenografts to a European elite through a licensed surgical network, Brinkley sold goat-gland implants to a national audience reached by radio, beginning at Milford, Kansas in 1917. The procedure rested on a pre-immunological and biologically untenable premise of cross-species tissue integration and was retired from medical practice as the underlying biology was understood and as regulators acted. It is a precursor in the same lineage as Niehans’s cellular therapy (1931) and, more distantly, modern stem-cell tourism; the distinguishing feature is the use of broadcasting to convert a surgical claim into a consumer product. No controlled outcome trial was ever conducted.
