Vaginal photoplethysmograph
Vaginal photoplethysmograph (pronunciation: /ˈvædʒɪnəl ˌfoʊtoʊˈplɛθɪzməˌɡræf/) is a device used in sexology and clinical psychology to measure changes in blood flow in the vagina.
Etymology
The term "vaginal photoplethysmograph" is derived from the Greek words "phōtos" (light), "plethysmos" (increase), and "graphō" (to write).
Function
The vaginal photoplethysmograph is a tampon-shaped device that uses light to measure changes in blood flow in the vaginal walls. These changes are often used as an indirect measure of sexual arousal in women. The device is inserted into the vagina, and a light source illuminates the blood vessels in the vaginal wall. The amount of light reflected back to the device changes as blood flow increases or decreases, providing a measure of sexual arousal.
