This work belongs to the first phase of the highly controversial research conducted by the French surgeon of Russian origin, Sergueï Abramovitch Voronoff (1866–1951).
Between 1917 and 1926, Voronoff carried out more than five hundred transplantations on sheep, goats, and even a bull, grafting the testicles of younger animals onto older ones.
His observations appeared to suggest that such transplantations restored vitality to ageing animals. From this, he went on to regard the transplantation of monkey glands as an effective treatment for human senility, leading him toward increasingly hazardous experimental grafts performed on humans.
Signed autograph inscription by Serge Voronoff on the half-title: "To Monsieur Ch. Homassel, with kind regards. S. Voronoff" (our own translation).
The recipient may be Charles Homassel (1872–1952), Chief Administrator of the Colonies.
