Shafer Width and Girth: The Use of Injectable Fillers for Penile Enhancement

Shafer Width and Girth: The Use of Injectable Fillers for Penile Enhancement

Injectable filler will be performed by Principal Investigator under sterile conditions for the enhancement of girth and surface area of the penis.

This prospective, single-arm, single-center study was conducted to evaluate the efficacy and safety of injectable dermal fillers for penile enhancement.

Prior to enrollment, each participant underwent a comprehensive consultation and provided written informed consent after receiving detailed information regarding the study objectives, procedures, potential risks, benefits, and available alternatives.

Following baseline evaluation (Day 1), including standardized photographic documentation and penile measurements, the procedure was performed under sterile conditions in an office-based setting by the Principal Investigator. Topical anesthesia was applied for approximately 10 minutes, after which participants were placed in supine position. A dorsal penile nerve block was administered using local anesthesia, followed by injections of study filler.

Participants returned approximately two weeks after the initial treatment for an additional treatment session, when clinically indicated to achieve the planned treatment goal. Follow-up evaluations were conducted at 2, 6, 12 weeks, and at 1year after treatment.

The primary efficacy endpoint was change in penile shaft girth from baseline. Safety assessments included systemic monitoring and documentation of treatment-related adverse events throughout the study period.

The study was conducted in accordance with the principles of the International Council for Harmonization Good Clinical Practice (ICH GCP) guidelines and was reviewed and overseen by the Institutional Review Board (IRB), Advarra.
