“…The relationship of estrogen level to sexual response has been studied in premenopausal women across the menstrual cycle. While some investiga-tors have reported a peak in sexual desire or activity midcycle when estrogen level is high (Adams, Gold, & Burt, 1978;Englander-Golden, Chang, Whitmore, & Dienstbier, 1980;Udry & Morris, 1968), methodological problems including accurate identification of menstrual cycle phase make interpretation of results difficult.
