PENILE GIRTH ENHANCEMENT WITH HYALURONIC ACID INJECTION: A SINGLE-CENTER STUDY

Abstract Objectives Penile girth enhancement using hyaluronic acid (HA) fillers is a sought-after procedure for men aiming to improve penile aesthetics and self-confidence. Despite its growing popularity, there is limited comprehensive data on patient outcomes and safety profiles. This study evaluates the safety and efficacy of subcutaneous HA injections for penile girth enhancement. Methods A retrospective audit of patient outcomes after penile girth enhancement with subcutaneous HA filler injections conducted at one Center between January 2022 and August 2024. The following data was collected: - Pre and post-operative flaccid penile girth. - Patient reported satisfaction rates. - Complications. The procedure was conducted under local anaesthesia and aseptic conditions. A puncture was made in the pubic hair line with an 18G spinal needle followed by the introduction of a 17G injection cannula. The HA filler was then injected dorso-laterally in a fan shapped manner in the areolar space between the dartos and Buck’s facia. The puncture site was sealed with tissue glue and a water proof dressing. Patients were instructed to massage the filler in order to maintain symmetry and to avoid intercourse for 3 weeks. Results 324 patients were included in this study, the mean patient age was 35 (22–65). The Mean follow up duration was 9 (2-24) months. The mean HA filler injected per patient was 15 (10-30) ml. The mean increase in flaccid girth was 2.5 (1.5-4) cm. The mean HA filler longevity was 12 (9-24) months. The patient reported satisfaction rates were 89%. No serious adverse events were encountered; the following complications were recorded: asymmetry; 20 patients (6.1%), managed by HA filler top up. Migration of HA filler in the foreskin; 25 patients (7.7%), managed by hylase injection. HA filler lumps; 15 patients (4.6%), managed by hylase injections. Infection; 5 patients (1.5%), managed with oral antibiotics. Four patients (1.2%) did not like the filler and wanted it removed which was done by hylase injections. Conclusions Penile girth enhancement by subcutaneous Hyaluronic acid injection is a safe and effective procedure which is associated with high patient-satisfaction rates. Conflicts of Interest None.
