Abstract
Cross-linked dextran and polymethylmethacrylate mixture (Lipen-10) is newly developed tissue filler. The purpose of this study was to evaluate tolerability and efficacy of Lipen-10 on penile enhancement. Twenty adult males were included in this study. Lipen-10 was injected into the subcutaneous tissue of the penile shaft. The penile girth and length were measured in the flaccid state, before and 1, 3 and 6 months after the injection. The circumference increased by 3.7±1.2 cm (50.8%, P<0.0001) at penile base, 4.2±0.9 cm (59.0%, P<0.001) at mid-shaft, and 3.8±1.0 cm (53.2%, P<0.0001) at distal shaft and the length increased by 2.3±1.4 cm (63.2%, P<0.001). There was, however, no significant difference between 3 and 6 months post-treatment in girth and length (P-values: 0.796, 0.498, 0.600 and 0.084 for penile base, mid- and distal-shaft and length, respectively). The complications were only one mild asymmetry of penile shape and one 5-mm-sized nodule in the injected site. There were no clinically significant adverse events in all subjects. Penile injection of Lipen-10 led to a significant increase in penile size, showed a good durability and was well-tolerated, without serious adverse events. These results suggest that penile injection of Lipen-10 may be a new effective method for penile enhancement.
