Objectives Over 50% of women in the United States report using sexual devices. These devices, which are often used recreationally to increase the likelihood of arousal and orgasm, can also be used therapeutically in the setting of sexual dysfunction. Despite their widespread use and association with improved sexual wellness, their effect on the clitoris has not been investigated. We aimed to evaluate changes in clitoral blood flow and size in response to stimulation with various sexual devices. Methods Clitoral sonography was performed on a healthy volunteer before and after stimulation with each of the following sexual devices: wand applied externally, internal vibrator inserted vaginally, and air pulse stimulation of the clitoral glans. The scans were obtained with a Philips Lumify™ ultrasound (Koninklijke Philips N.V., Amsterdam, Netherlands) using a L12-4 linear array transducer (4–12MHz) and a C5-2 broadband curved array transducer (2–5MHz). Results We observed that stimulation with sexual devices increased blood flow to different areas of the clitoris and led to changes in clitoral area and clitoral erectile length (CEL). Conclusion Our findings suggest that there are more than 1 or 2 types of female orgasms (i.e., clitoral versus vaginal), which likely cover a spectrum. This may provide insights into using sexual devices as treatment options for female sexual dysfunction.
