641 Vibrators and Other Sex Toys are Commonly Recommended to Patients, But Does Size Matter? Dimensions of Commonly Sold Products Debby Herbenick, PhD, MPH,* Kathryn J. Barnhart, MPH,* Karly Beavers, † and Stephanie Benge, MS* *Center for Sexual Health Promotion, School of Public Health, Indiana University, Bloomington, IN, USA; †California State University, Monterey Bay, CA, USA DOI: 10.1111/jsm.12798 ABSTRACT Introduction. Vibrators and dildos are commonly used by women and men in the United States, and are increasingly recommended by clinicians. In addition, sex toys and various household objects are sometimes used for sexual stimulation in ways that pose health risks to their users. Data about the dimensions of such products may inform clinicians’ recommendations. Aim. The purpose of the present study was to assess the sizes (length and circumference) of vibrators and dildos marketed for vaginal or anal insertion on websites that sell sexual enhancement products. Methods. Eight websites that sell sexual enhancement products were identified for inclusion in the study. The dimensions of vaginal vibrators and dildos listed for sale on each website were noted, and descriptive data were calculated for each website. Main Outcome Measures. Product length and circumference (mean, median, and range). Results. Popular sex toy distributers offer a variety of product sizes. The length of many vibrators and dildos was sized between 4 and 6 in, and circumference was between 4 and 5 in. However, some companies featured products of a considerably larger size than others. Conclusion. Length and circumference of vibrators and dildos varied, but on average approximated mean penile dimensions. Clinicians’ recommendations for use of vaginal or anal products can be enhanced by familiarity and offering additional information about product sizes and retailers.
