Mikhail Mikhailovich Zavadovsky (German form Zawadowsky); 29 July 1891 - 28 March 1957) was a Russian and Soviet biologist who specialized in the reproductive biology of livestock. A professor at Moscow University, he conducted experiments on sex hormones, the control of sexual characters and hormonal cycles. He noted that there was a balance between the sex hormones and was able to produce male or female characteristics during development by altering the balance experimentally. He termed them plus-minus interactions. Zavadovsky introduced the term "biotechnology" in 1932. His brother Boris Mikhailovich (1895-1951) also worked on endocrinology.

Presentation copy, inscribed by Zavadovsky to Raymond Pearl (1879-1940) on the front free endpaper: "An sehr geerhrten Herrn Prof. R. Pearl, M. Zavadovsky. Moscau Universität Institut Exper. Zool." Pearl's bookplate on the front pastedown. First Edition. Zavadovsky, an experimental biologist, studied the development of primary and secondary sexual characteristics in domestic and laboratory animals. "Detailed studies of the effects of castration and the transplantation of sex glands in chickens led him to conclude that some of the secondary sexual characteristics depend on their development in the hormones of the sex glands and that some are independent of it. . . . Zavadovsky established that the monosexuality of female birds and the bisexuality of the male-and the opposite among mammals and amphibians-correspond to the distribution of sex chromosomes: XY in female and XX in male birds, and the reverse among mammals and amphibians. Zavadovsky investigated the interrelationships between secondary sexual characteristics and the sex glands and studied the interaction of the endocrine glands. He concluded that a ± mutual influence exists: an organ that stimulates another also is inhibited by it. This was an important application to biology of the cybernetic principle of positive or negative feedback" (Dictionary of Scientific Biography). Zavadovsky presented this copy of his work to American biologist and biostatistician Raymond Pearl; see Garrison-Morton 137, 1712, 1714. .

"Zusammenfasung: Bei der Analyse von Zwittererscheinungen ist folgendes zu berücksichtigen: 1. Die sekundären Gechlechtsmerkmale können der Mechanik ihrer Entwicklung nach, in drei Gruppen geteilt werdn: 1. <psudosexuelle, 2. Eusexuelle, 3. Somosexuelle. Bei hybriden Individuen ist noch an die 4. Konkordosexuelle Gruppe zu denken. 2. Die Geschelchtsmorphohormon, welches die sexuellen Merkmale enttwickelt, bleibt nur kurze Zeit im Blut" (24 Stunden oder etwa" länger). 3. Nachdem das Morphohormon entfernt, ist, beginnen einige von den unabhängigen Merkmalen "ich umgekehrt zu entwickeln, andere dieser Umkehrentwicklung nicht unterworfen sind. Die ersten können wir kurz Reversible nennen, die zweiten Irreversible. 4. Einige der eusexuellen Merkmale (z. B. Federpigmenten einer Henne) bedürfen für ihre Entwicklung einer beständigen Wirkung des Morphohormons. 5. Andere eusexuelle Merkmale (z. B. die Hörner der Schafe) verlangen nur einen Stoß von dem Morphohormon und können sich ohne seine Hilfe weiterentwickeln. 6. Diese Fähigkeit des Gewebes, welches einen Stoß von Seiten des Morphohormons verlangt, um sich ohne seine Hilfe weiter zu entwickeln, habe ich als die Reaktionsträgheit des Gewebes zu bezeichnen vorgeschlagen. 7. Der Entwicklungsgrad einiger Merkmale (z. B. die Menge des Pigmentes) ist der Menge des Morphohormons proportional. 8. Der Entwicklungsgrad anderer Merkmale ist möglicherweise dem Gesetze "Alles oder Nichts" untergeordnet. 9. Diejenigen Gewebe, welche eusexuelle Merkmale entwickeln, haben verschiedene Reizschwellen. Man kann daher diese Gewebe ihrer Reizschwelle nach anordnen. 10. Während der Regeneration der Geschlechtsdrüse treten die Merkmale in einer bestimmten Reihenfolge auf; wenn die Geschlechtsdrüse zugrunde geht, verschwinden diese Merkmale in umgekehrter Reihenfolge. 11. Es ist nicht möglich alle eusexullen Merkmale ihrer Reizschwelle nach anzuordnen. Dieser Umstand spricht dafür, daß das Geschlechtshormon (in unserem Falle das der Henne) aus unabhängigen Komponenten besteht."
