This report covers the results of an interview survey concerning sexual responses of 124 women during the perimenopause (menopause transition), and the results of 52 women's prospective coital behavior records over 3 months with concomitant steroid analysis. Results indicated that in general, the age group centering around 49 years appears not to be suffering from a particular sexual deficit in the dimensions of desire, response, or satisfaction in their sexual life, and a subset of women with especially low estradiol levels (less than 35 mg/pl) tends to have reduced coital activity.
