To develop a new noninvasive technique to measure vulval blood flow changes during sexual arousal; 18 healthy volunteers between the age of 20 and 33 years were studied. Each subject underwent two experimental sessions at least 2 weeks apart to coincide with the proliferative and luteal phases of her menstrual cycle. An initial laser Doppler perfusion imaging (LDPI) scan of the vulva was performed. The subject was then given a chapter of erotic fiction to read and a repeat LDPI scan was performed immediately after. The percentage change in flux were calculated: the clitoral skin blood flow increased by 26.4% (P < 0.05), labial skin blood flow by 24.9% (P < 0.05) and the posterior fourchette skin blood flow by 35.3% (P < 0.05). LDPI can detect changes in vulval perfusion during the sexual arousal response and could be used to compare healthy subjects with female sexual dysfunction patients, as well as for assessing the benefits of any treatment for this condition.
为开发一种新的非侵入性技术来测量性唤起过程中外阴血流变化；对18名年龄在20至33岁之间的健康志愿者进行了研究。每位受试者至少间隔2周进行两次实验，以对应其月经周期的增殖期和黄体期。首先对外阴进行激光多普勒灌注成像（LDPI）扫描。然后让受试者阅读一章色情小说，并在阅读后立即进行重复LDPI扫描。计算血流量的百分比变化：阴蒂皮肤血流量增加了26.4%（P<0.05），阴唇皮肤血流量增加了24.9%（P<0.05），后阴唇系带皮肤血流量增加了35.3%（P<0.05）。LDPI能够检测性唤起反应期间外阴灌注的变化，可用于将健康受试者与女性性功能障碍患者进行比较，也可用于评估针对这种情况的任何治疗的益处。
