"Using thermography, we also found that women's subjective experience of sexual arousal corresponded with their physiological genital response; this challenges the common notion that women don't know their bodies," says Tuuli Kukkonen, a Ph.D. candidate in psychology at McGill University and lead author of the study.
"I predict that the major physiological measure of sexual arousal for most future clinical trials of female sexual arousal disorder will be genital temperature as measured by thermography," according to Dr. Yitzchak Binik, senior author of the research and Professor of Psychology at McGill and Director of the Sex and Couple Therapy Service of the McGill University Health Center (www.sexandcoupletherapy.com).
"This is a huge breakthrough in the assessment of genital blood flow research in women's sexual health," observed Irwin Goldstein, Editor-in-Chief of The Journal of Sexual Medicine. "Previous testing was invasive and involved placement of measuring instruments in various locations in the genital region and this interfered with the arousal itself. Thermography does not have any such requirements and is very user-friendly. This may be the first test to diagnose blood vessel blockage as a cause of sexu al dysfunction in women, and may help identify those patients who may be helped by vasoactive drugs similar to those prescribed for men with erectile dysfunction from narrowed blood vessels."
