Serge Abrahamovitch Voronoff (Russian: Сергей Абрамович Воронов; c. July 10, 1866 – September 3, 1951) was a French surgeon of Russian origin who gained fame for his practice of xenotransplantation of monkey testicle tissues onto the testicles of men for purportedly as anti-aging therapy while working in France in the 1920s and 1930s.

His practices made him significantly wealthier. However, his theories remained controversial throughout his life, and he was often ridiculed by medical professionals over his claims. According to one contemporary newspaper, he was famously known as the "monkey gland man."[1] Ultimately almost all his works were later proven false.
