DETAILED ILLUSTRATED REPORT OF NEARLY 500 CASES OF TRANSPLANTION OF 'MONKEY GLANDS' TO HUMANS. 8 1/4 inches tall paperback book, color printed cover, lightly soiled, containing 39 photographic illustrations of surgical technique and histologic sections, and table listing statistical summary of 475 cases of simian testicular grafting upon man, 125 pages. Very good. SERGE ABRAHAMOVITCH VORONOFF (1866 - 1951) was a French surgeon of Russian extraction who gained fame for his technique of grafting monkey testicle tissue on to the testicles of men for purportedly therapeutic purposes while working in France in the 1920s and 1930s. His work was ridiculed by the medical establishment. In November 1991, The Lancet, suggested that Voronoff's work be revisited. In particular, since modern medicine has established that the Sertoli cells of the testes constitute a barrier to the immune system, rendering the testes an immunologically privileged site for the transplantation of foreign tissue, the thin slices of monkey testicles Voronoff implanted into the patient's testicles may in theory have survived to produce some benefit. As recently as 2005, Voronoff's work in the 1920s and 1930s was noted for setting the basis for the modern anti-aging strategy of replacing hormones. Such practices are currently advocated by alternative medicine organizations such as the American Academy of Anti-Aging Medicine.
