In a series of studies by Winnifred B. Cutler, PhD and colleagues at the University of Pennsylvania and later at Stanford University it was found that regular sexual contact had an important impact on physical and emotional well being of women. Sexual contact with a partner at least once a week led to more fertile, regular menstrual cycles, shorter menses, delayed menopause, increased estrogen levels, and delayed aging. Brain imaging studies at UCLA have shown that decreased estrogen levels are associated with overall decreased brain activity and poor memory. Enhancing estrogen levels for women through regular sexual activity enhances overall brain activity and improves memory.
