The influence of age and cycling status on sexual arousability in women

The effects of age and hormonal status on sexual response were quantitatively assessed by the use of a vaginal photoplethysmograph to measure changes in pulse amplitude in response to erotic film and fantasy. In young, regularly cycling women (mean age, 31 years) there were no significant differences in sexual response between the follicular, ovulatory, and luteal phases. The older premenopausal women (mean age, 51 years) showed responses not significantly different from those of the young cycling women. However, both the younger cycling women and older premenopausal women had significantly higher responses to erotic film than the postmenopausal women (mean age, 57 years). It was concluded that the menopause does result in a decrease in sexual response as assessed by vaginal pulse amplitude. However, it was not established that the magnitude of change noted is sufficient to cause any sexual dysfunction.
