• The Monkey Gland Immortality

  The Monkey Gland Immortality theory grew out of the 1920s rejuvenation craze surrounding surgeon Serge Voronoff, who became internationally famous for transplanting slices of monkey testicular tissue into aging men in the hope of restoring vigor, virility, and longevity. While many wealthy patients and journalists treated the operations as cutting-edge anti-aging science, critics argued that the procedure was not merely fraudulent or dangerous but part of a deeper assault on human integrity. In its conspiratorial form, the theory held that monkey-gland transplantation was a deliberate program to animalize, de-evolve, or biologically confuse humanity under the guise of medical progress. Because the operations were real, high-profile, and tied to elite clientele, the theory became one of the most striking examples of biomedical modernity being reimagined as a hidden species-level threat.
