Alfred Kinsey and colleagues at Indiana University had published two volumes on sexual behavior in the human male and female (known as the Kinsey Reports), in 1948 and 1953, respectively, both of which had been revolutionary and controversial in their time. Kinsey's work however, had mainly investigated the frequency with which certain behaviors occurred in the population and was based on personal interviews, not on laboratory observation. In contrast, Masters and Johnson set about to study the structure, psychology, and physiology of sexual behavior, through observing and measuring masturbation and sexual intercourse in the laboratory.
