A patient presented with scrotal cellulitis as a complication of infusing 900 ml saline into his scrotum. He had obtained a kit along with explicit instructions for performing the infusion through the Internet. This practice may be more widespread than expected. An Internet search revealed many references to this procedure, but a MEDLINE search showed virtually no information in the medical literature. Patients who are considering scrotal inflation, as it is called in the lay literature, should be warned of the potential complications of this procedure.
