  • Patent number: 8607799
    Abstract: A male chastity comprises a first loop, a cup, a second loop hinged to the first loop and optionally to the cup, and a removable fixing mechanism. The first loop is configured for being traversed by the user's penis and scrotum, and for encircling the penis behind the scrotum. The second loop is configured for being traversed by at least the penis, and for encircling the penis ahead of the scrotum, so that the user's testicles are located between the first loop and second loop. The cup is configured for enclosing at least a head of the penis. The removable fixing mechanism is configured, when joined to the device, for preventing removal of the device form the penis by limiting or blocking relative rotation between the first loop and the second loop, and, if needed, by limiting or blocking relative rotation between the cup and the second loop.
