Masters and Johnson

Gynecologist William Howell Masters (December 27, 1915 – February 16, 2001) and psychologist Virginia Eshelman Johnson (born February 11, 1925) pioneered research into the nature of human sexual response and the diagnosis and treatment of sexual disorders and dysfunctions from 1957 until the 1990s.

Sexual Response in the Aging Male and Female

Masters and Johnson were the first to conduct research on the sexual responsivity of older adults, finding that given a state of reasonably good health and the availability of an interested and interesting partner, there was no absolute age at which sexual abilities disappeared. While they noted that there were specific changes to the patterns of male and female sexual responses with aging -- for example, it takes older men longer to become aroused and they typically require more direct genital stimulation, and the speed and amount of vaginal lubrication tends to diminish with age as well -- they noted that many older men and women are perfectly capable of excitement and orgasm well into their seventies and beyond.
