Aim. The labial photoplethysmograph (LP), a new measure for assessing genital responses in women, was compared to the vaginal photoplethysmograph (VP).
Methods. Fifteen women wore both devices simultaneously while viewing neutral, sexual, sexually-threatening, and threatening film clips.
Results. The LP and VP exhibited comparable specificity to sexual stimuli. Additionally, the LP demonstrated greater resistance to movement artifacts and a slightly higher correspondence with subjective measures of sexual arousal.
Conclusion. The LP, while somewhat more difficult to place and less comfortable than the VP, is a promising new measure of genital response in women that warrants further development.
