Boston: Little, Brown and Company, 1966.  First Edition of the co-authors' first book.

Inscribed "with compliments" and signed by both Masters and Johnson.  An uncommonly nice copy, externally fine, binding slightly cocked, edges of text block lightly foxed (not affecting internal text), slight tinge of offsetting from front flap, in a fine dust wrapper save for some light edge wear.

"After many years of secretly documenting how the human body responds during sex—and coming up with remarkably effective treatments for their patients—Masters and Johnson became suddenly famous with the publication of their first landmark book.

In a real sense, Masters and Johnson symbolized the triumph of modernity and medicine over religious taboos and cultural ignorance. Their “facts of life” felt far more definitive than ancient religious screeds or even Freud’s theories. Sex had left the church and entered the clinic. Instead of consulting with black-clad ministers or rabbis, Americans would rely on doctors in crisp white. At great risk to their livelihoods and reputations Masters and Johnson provided men and, particularly, women with the freedom and fundamental knowledge to make vital choices in their relationships, while highlighting medicine’s position at the forefront of social debates about human sexuality."
