"OBJECTIVE: To assess the efficacy of a vacuum device as a noninvasive method for penile elongation. PATIENTS AND METHODS: Between September 2003 and November 2004, 37 sexually active men with a stretched penis length of <10 cm were given vacuum treatment three times a week, for 20 min on each occasion, for 6 months. RESULTS: After 6 months, the mean penile length had increased from 7.6 cm to 7.9 cm (no significant difference). The efficacy of vacuum treatment was approximately 10%, and the patient satisfaction rate was 30%. There was one case of haematoma of the penis and one of glans numbness, both resolved spontaneously without any intervention. CONCLUSION: Vacuum treatment of the penis is not an effective method for penile elongation, but provides psychological satisfaction for some men."
