BACKGROUND There is no well-defined male buttock aesthetic. The authors performed a crowdsourced analysis in order to define the ideal male buttocks. METHODS A survey was deployed using the Amazon MTurk platform. Respondents rated a panel of digitally altered male buttocks from most to least attractive using three views. Respondents were asked questions pertaining to their own interest in gluteal augmentation, self-reported body type, and other demographics. RESULTS A total of 2,095 responses were recorded; 61% were male, 52% were between the ages of 25-34, and 49% were Caucasian. The preferred lateral ratio in the AP dimension was 1.18, the oblique angle between the sacrum, lateral gluteal depression, and point of maximal projection of the gluteal sulcus was 60 degrees, and posterior ratio between the waist and maximal width of the hips was .66. This corresponds to moderate gluteal projection in the lateral and oblique views, with a narrower gluteal width and defined trochanteric depression in the posterior view. Loss of the trochanteric depression was associated with lower scores. Subgroup analysis revealed differences when stratified by region, race, sexual orientation, employment industry, and athletic interest. No appreciable difference was found based on respondent gender. CONCLUSIONS Our results demonstrate that there is a preferred male gluteal aesthetic. This study suggests that males and females favor a more projected male buttock with a more pronounced contour, but preferred a narrow width with defined lateral depression. These findings have the potential to guide future aesthetic gluteal contouring techniques in males.
