Abstract

Infrared thermography (IRT) is a non-contact technique that permits mapping and analysis of the temperature of the body's skin surface. This method has been applied to sexual psychophysiology since the 1980s and its use has been expanding ever since, mainly because it provides several advantages over existing genital response measures. This article presents a review of experimental studies employing IRT to investigate human sexual arousal, with the aim of summarizing the available procedures and evidence so far and to identify important caveats in the literature. The studies reviewed support the feasibility and validity of IRT as a real-time physiological measure of sexual arousal but varied substantially regarding methodology and procedures. The results of this review underscore the value and validity of IRT in sexual psychophysiology and point at the critical need for the standardization of IRT protocols to accommodate the specific needs of applying this methodology to sexual physiology.
