244 L. A. Brotto et al.Current knowledge on this subject. Although subjective aspects of the sexual response inpostoperative male-to-female (MTF) women withGender Identity Disorder has been studied extensively,almost no data exist on physiological patterns of sexualarousal in this group of new women.. The study has implications for the use of vaginalphotoplethysmography, a technique used widely in themeasurement of sexual arousal in natal women, forMTF women.What this study adds. This study suggests that the vaginal photoplethysmographcannot be considered a viable technique to studythe blood flow patterns in the neovagina duringconditions of sexual arousal in MTF women due tomovement artefacts.. Given that this group of women became subjectivelysexually aroused to erotic stimuli in the laboratorysetting, researchers might explore other methods ofphysiological sexual arousal assessment less susceptibleto movement artifacts for furthering our understandingof the sexual response in new women.
