Aim: To report our experience with penile girth augmentation using liquid injectable silicone.

Methods: Between August 2003 and July 2006, 324 men (mean age 35 years, range 19-65 years) received a series of liquid silicone subcutaneous injections between the penile skin and the corpora cavernosa on the dorsal and lateral aspects of the penile shaft, under local anesthesia. Digital photographs taken pre- and post-procedure (n = 324), and penile contour measurements (n = 30) yielded objective results. Subjective results were derived from patient and partner testimony of satisfaction. Follow-up averaged 20 months (range 1-36 months).

Results: Three hundred and twenty-four procedures were primary augmentations. Most men (61%) were married, 7% were accompanied by their partners, and 93% were circumcised. The mean measured penile circumference was 9.5 cm (7.5-11.5 cm) pretreatment and 12.1 cm (10.3-15.3 cm) post-treatment (mean increase of 27% in circumference and 0.84 cm in diameter). Patient and partner satisfaction was already expressed after the first two treatments. Sexual activity could be resumed after 8 h. Complications (mild bruising) were easily resolved.

Conclusion: Penile girth augmentation using liquid injectable silicone yields very satisfactory short-term results with no immediate or short-term complications.
