Summary: Penile volumization using hyaluronic acid fillers has emerged as a minimally invasive alternative for men seeking aesthetic enhancement of penile girth. Hyaluronic acid fillers have emerged as a nonsurgical option for penile girth enhancement, with studies reporting favorable safety profiles. This case report details the treatment of a 35-year-old man, outlining procedural steps, patient outcomes, and safety considerations. The patient had normal endocrine function with no history of endocrine disorders. A supplementary video documenting the injection technique has been included. Ultrasound image guidance was used to confirm accurate placement of the filler (e.p.t.q.® Lidocaine S 300, JETEMA Co., Ltd. Korea) within the intended anatomical plane, between the dartos fascia and Buck fascia. Outcomes demonstrated a significant increase in penile circumference, from 12.3 to 13.0 cm, with high patient satisfaction and no major complications. This report described a technical approach using ultrasound guidance and anatomical considerations in a single patient; further research is necessary to evaluate outcomes in a larger cohort.
