The authors created the glans penis augmentation by injectable hyaluronic acid gel and reported the 6-month result for premature ejaculation. In a total of 38 patients, long-term effects of 5 years were compared to those of 6 months in terms of residual volume of implants and efficacy on premature ejaculation. Maximal glandular circumference measured by tapeline significantly decreased by 15% (P<0.05) but mean patient's visual estimation (Gr 0-Gr 4) did not decrease (3.60 vs 3.56, P>0.05). Compared to 6-month follow-up, intravaginal ejaculatory latency time and vibratory threshold decreased at 5 years (P<0.05), but still well increased considering those of preaugmentation. Hence, 76% of patients and 63% of partners were still satisfied. There was no serious adverse reaction. In the 5-year long-term follow-up of glans penis augmentation by filler, the implants were well maintained and effective for glans penis hypersensitivity in premature ejaculation patients.
