Typically male narrow hips are often corrected by buttock implants. The proportions of the whole figure change when the buttocks are correctly shaped. The waist-to-hip ratio (WHR) is a common indicator of the distribution of body fat that is different in genetic men and women. The use of an implant allows for the correction of the value of this indicator, thus bringing it closer to the ideal female figure. Depending on the expected effect, the implant is placed under or on the gluteal muscle.
