Claim · 1917 · Brinkley goat-gland transplantation (goat-to-human gonad implant)
Surgical implantation of goat gonad tissue restores male sexual function, potency, and fertility in the recipient.
The potency-restoration claim was the original basis for demand for Brinkley’s operation, marketed first to men reporting impotence (Smith 2022). It rested on patient testimony and promotional case reports (Flower 1921) without controlled comparison, blinding, or objective endocrine measurement. It is refuted by the immunological rejection of the implanted tissue and the absence of any hormone delivery from the graft; the reported effects are consistent with placebo response and postoperative attention.
