Adult male circumcision reduces HIV transmission through vaginal intercourse and is being promoted in areas where HIV is widespread. Conventional surgical circumcision involves suturing and thus requires practitioners with surgical skills. It is also associated with complications, including bleeding and infection, especially in resource-poor settings. The ShangRing (Wuhu Snnda Medical Treatment Appliance Technology Co. Ltd, Wuhu City, China) has been used to perform thousands of circumcisions in adult men, principally in China. It consists of two concentric plastic rings that sandwich the foreskin of the penis, allowing circumcision without stitches or notable bleeding. As well as substantially reduced operative times, ShangRing adult male circumcision is associated with a low complication rate, and the technique can easily be taught to both physician and nonphysician personnel. The simple technique and successful outcomes associated with the ShangRing procedure mean that the device could enable standardization of adult male circumcision, helping HIV prevention efforts throughout the developing world.
