Fig. 3. Changes in penile girth at week 4, 12, and 24 were significantly increased in both HA and PLA groups compared to the baseline (all p<0.0001). There was no significant difference between groups in increase of penile girth compared to baseline at all time points (at 4 weeks, p=0.073; at 12 weeks, p=0.089; at 24 weeks, p=0.092). HA: hyaluronic acid, PLA: polylactic acid.
