HA, hyaluronic acid; PLA, polylactic acid; n, number of patients; SD, standard deviation. * Student’s t test. ** Fisher’s exact test. † The mean penile girth was defined as the mean of the circumference measures on distal, mid-, and proximal shafts. †† Satisfactions were assessed with a 5-point visual analogue scale, with 1 indicating very dissatisfied and 5 indicating very satisfied.
