[Vasectomy using the Li method].

The no-scalpel vasectomy is described and evaluated. Nineteen out of 21 consecutive patients could be operated with this technique. The median operating time was 16 minutes, range 9-50 minutes. There were no complications and the scar was barely visible after ten days. The median score for pain was 0.4 cm (range 0.0-5.0 cm) and for discomfort 0.7 cm (range 0.0-5.0 cm) on a 10 cm long visual analogue scale. The method is minimally invasive and well-tolerated by the patients. When some routine is gained the operating time is short.
