Human Sexual Inadequacy
The Masters and Johnson research team, composed of William Masters and Virginia E. Johnson, pioneered research into the nature of human sexual response and the diagnosis and treatment of sexual disorders and dysfunctions from 1957 until the 1990s.
In the initial phase of their studies, from 1957 until 1965, they recorded some of the first laboratory data on the anatomy and physiology of human sexual response based on direct observation of 382 women and 312 men in what they conservatively estimated to be "10,000 complete cycles of sexual response."
Their findings, particularly on the nature of female sexual arousal dispelled many long standing misconceptions. They jointly wrote two classic texts in the field, Human Sexual Response and Human Sexual Inadequacy, published in 1966 and 1970 respectively. Both of these books were best-sellers and were translated into more than thirty languages.
