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.
Serge (Samuel) Voronoff was born to a Jewish family in the village Shekhman, Tambov Governorate in Russia (now Tambov Oblast) shortly before July 10, 1866, the date of his circumcision in a synagogue. His father Abram Veniaminovich Voronov was a former cantonist[2] and a distiller;[3] his mother was Rachel-Esther Lipsky.[4][5][6] At the age of 18, after graduating from the Voronezh Realschule, he emigrated to France, where he studied medicine. In 1895 at the age of 29, Voronoff became a naturalized French citizen. Voronoff was a student of French surgeon, biologist, eugenicist, and Nobel Prize recipient Alexis Carrel, from whom he learnt surgical techniques of transplantation. Between 1896 and 1910, he worked in Egypt, studying the retarding effects that castration had on eunuchs, observations that would lead to his later work on rejuvenation.
Voronoff married his first wife, Marguerite Barbe, in 1897. She died in 1910. He married his second wife, Evelyn Bostwick, in 1920 (Bostwick's daughter from a previous marriage was Marion "Joe" Carstairs). Bostwick translated Voronoff's book, Life: a means of restoring vital energy and prolonging life, into English. She died on March 3, 1921, at the age of 48. Her legacy gave Voronoff a large income for the rest of his life.[7]
Ten years later, Voronoff married Gerti Schwartz, believed by some to be the illegitimate daughter of King Carol of Romania.[8] She outlived him and became the Condesa da Foz upon Voronoff's death.
Voronoff died on September 3, 1951, in Lausanne, Switzerland, from complications following a fall.[9] While recovering from a broken leg, Voronoff suffered chest difficulties, thought either to be pneumonia or possibly a blood clot from his leg that moved to his lungs.[9]
Few newspapers ran obituaries, and some of those that did acted as if Voronoff had always been ridiculed for his beliefs. For example, The New York Times, once one of his supporters, spelt his name incorrectly and stated that "few took his claims seriously".[9] On the other hand, TimesDaily was more positive, calling him a "famed prononent proponent of rejuvenation for humans through monkey glands" and claiming that he actually became more popular later in life: "Medical authorities at first rejected his theories, but later developments confirmed some of his ideas."[1]
Voronoff is buried in the Russian section of the Caucade Cemetery in Nice.
In the late nineteenth century and early twentieth century, trends in xenotransplantation included the work of Charles-Édouard Brown-Séquard.[10][11] In 1889, Brown-Séquard injected himself under the skin with extracts from ground-up dog and guinea pig testicles. These experiments failed to produce the desired results of increased hormonal effects to retard aging.
Voronoff's experiments launched from this starting point. He believed glandular transplants would produce more sustained effects than mere injections. Voronoff's early experiments in this field included transplanting thyroid glands from chimpanzees to humans with thyroid deficiencies. He moved on to transplanting the testicles of executed criminals into millionaires, but, when demand outstripped supply, he turned to using monkey testicle tissue instead.[12]
In 1917, Voronoff began being funded by Evelyn Bostwick, a wealthy American socialite and the daughter of Jabez Bostwick.[13] The money allowed him to begin transplantation experiments on animals. Bostwick also acted as his laboratory assistant at the Collège de France in Paris, and consequently became the first woman admitted to that institution.[14] They married in 1920.
Between 1917 and 1926, Voronoff carried out over five hundred transplantations on sheep and goats, and also on a bull, grafting testicles from younger animals to older ones. Voronoff's observations indicated that the transplantations caused the older animals to regain the vigor of younger animals.[15] He also considered monkey-gland transplantation an effective treatment to counter senility.[16]
His first official transplantation of a monkey gland into a human took place on June 12, 1920.[17] Thin slices (a few millimetres wide) of testicles from chimpanzees and baboons were implanted inside the patient's scrotum, the thinness of the tissue samples allowing the foreign tissue to fuse with the human tissue eventually.[17] By 1923, 700 of the world's leading surgeons at the International Congress of Surgeons in London, England, applauded the success of Voronoff's work in the "rejuvenation" of old men.[18]
In his book Rejuvenation by Grafting (1925),[19] Voronoff describes what he believes are some of the potential effects of his surgery. While "not an aphrodisiac", he admits the sex drive may be improved. Other possible effects include better memory, the ability to work longer hours, the potential for no longer needing glasses (due to improvement of muscles around the eye), and the prolonging of life. Voronoff also speculates that the grafting surgery might be beneficial to people with "dementia praecox", the mental illness known today as schizophrenia.
Voronoff's monkey-gland treatment was in vogue in the 1920s.[21][22] The poet E. E. Cummings sang of a "famous doctor who inserts monkeyglands in millionaires", and Chicago surgeon Max Thorek, for whom the Thorek Hospital and Medical Center is named, recalled that soon, "fashionable dinner parties and cracker barrel confabs, as well as sedate gatherings of the medical élite, were alive with the whisper - 'Monkey Glands'."[23]
By the early 1930s, over 500 men had been treated in France by his rejuvenation technique (including Voronoff's younger brother Georges[24]), and thousands more around the world, such as in a special clinic set up in Algiers.[25] Noteworthy people who had the surgery included Harold McCormick, chairman of the board of International Harvester Company.[26][27][28] To cope with the demand for the operation, Voronoff set up his own monkey farm in Ventimiglia, on the Italian Riviera, employing a former circus-animal keeper to run it.[23] French-born U.S. coloratura soprano Lily Pons was a frequent visitor to the farm.[29] With his growing wealth, Voronoff occupied the whole of the first floor of one of Paris's most expensive hotels, surrounded by a retinue of chauffeurs, valets, personal secretaries and two mistresses.[30]
Voronoff's later work included transplants of monkey ovaries into women. He also tried the reverse experiment, transplanting a human ovary into a female monkey, and then tried to inseminate the monkey with human sperm. The notoriety of this experiment resulted in the novel Nora, la guenon devenue femme (Nora, the Monkey Turned Woman) by Félicien Champsaur. In 1934, he was the first to officially recognise scientific work done by Greek Professor Skevos Zervos.
Voronoff's experiments ended following pressure from a sceptical scientific community and a change in public opinion.[31] It became clear that Voronoff's operations did not produce any of the results he claimed.
In his book The Monkey Gland Affair, David Hamilton, an experienced transplant surgeon, discusses how animal tissue inserted into a human would not be absorbed, but instantly rejected. At best, it would result in scar tissue, which might fool a person into believing the graft is still in place. This means the many patients who received the surgery and praised Voronoff were "improved" solely by the placebo effect.
Part of the basis of Voronoff's work was that testicles are glands, much like the thyroid and adrenal glands. Voronoff believed that at some point, scientists would discover what substance the testicular glands secrete, making grafting surgery unnecessary.
Eventually, it was determined that the substance emitted by the testicles is testosterone. Voronoff expected that this new discovery would prove his theories. Testosterone would be injected into animals and they would grow young, strong, and virile. Experiments were performed, and this was not the case. Besides an increase in some secondary sexual characteristics, testosterone injections did little. Testosterone did not prolong life, as Voronoff expected. In the 1940s, Kenneth Walker, an eminent British surgeon, dismissed Voronoff's treatment as "no better than the methods of witches and magicians."[32]
In the 1940s, his treatment was widely used by football players at Wolverhampton Wanderers and Portsmouth, although it eventually fell out of favour.[33]
By 1935, rejuvenation operations on testes were obsolete.[34] Kozminski and Bloom (2012) wrote that Voronoff's experiments were "plagued by secrecy, subjectivity and sensationalism", adding that the era of testosterone surgery was ended by a "lack of verifiable data".[34] They write that Voronoff and others can be faulted for "paternalistic use of patients and misogynistic message of testicular power", but that efforts such as these in the history of urology may have helped fuel medical progress.[34] They conclude that "the boundary between legitimate practice … and the self-interest of chicanery must be abrogated" with medical and regulatory vigilance.[34]
Haber (2004) stated that "Despite increasing doubts about the efficacy of his operation, he continued to perform both human and animal operations to popular acclaim."[35] In 2005, Kahn stated that the work by Voronoff and others in the 1920s and 1930s was the basis for rejuvenation therapy, but that the therapies developed then "received widespread attention (including ridicule) in the popular press, were spread rapidly by practitioners of questionable training and ethical motivation, and finally and relatively quickly disappeared from common use".[36]
As Voronoff's work became famous in the 1920s, it began to be featured in popular culture. By 1994, there were calls for a qualified apology from the orthodox medical establishment for dismissing Voronoff's work.[30] In 1998, the sweeping popularity of Viagra brought forth references to Voronoff in the popular press.[32][37] By 2003, Voronoff's efforts in the 1920s reached trivia factoid status for newspapers.[38]
"The Adventure of the Creeping Man" is a Sherlock Holmes short story by Arthur Conan Doyle, first published in March 1923 but set in 1903. In the story, an elderly professor is found to be regularity injecting himself with a substance called "extract of langur" for the purpose of rejuvenation. This has unexpected consequences for him.
The song "Monkey-Doodle-Doo", written by Irving Berlin and featured in the Marx Brothers film The Coconuts, contains the line: "If you're too old for dancing/Get yourself a monkey gland". Strange-looking ashtrays depicting monkeys protecting their private parts, with the phrase (translated from French) "No, Voronoff, you won't get me!" painted on them began showing up in Parisian homes.[39] At about this same time, a new cocktail containing gin, orange juice, grenadine and absinthe was named The Monkey Gland.[40]
Voronoff was the prototype for Professor Preobrazhensky in Mikhail Bulgakov's novel Heart of a Dog, published in 1925.[41] In the novel, Preobrazhensky implants human testicles and pituitary gland into a stray dog named Sharik. Sharik then proceeds to become more and more human as time passes, picks himself the name Polygraph Polygraphovich Sharikov, makes himself a career with the "department of the clearing of the city from cats and other vile animals", and turns the life in the professor's house into a nightmare until the professor reverses the procedure.
In his autobiography A Chef's Tale, Pierre Franey relates how when Voronoff dined at Le Pavillon in the 1940s, waiters would remark how "he looked like a monkey himself, with his exceptionally long fingers and slouching walk. They would laugh at him in the kitchen and imitate his walk for those of us (in the kitchen) who couldn't witness it ourselves."[42]
