Device for producing an effect upon a male reproductive system or part thereof

A device for producing at least one effect on a male reproductive system or at least one part thereof, the device comprising:

• a rigid cup for a penis head of a penis;
• coupling means for coupling the rigid cup to the penis with the penis head inserted in the cup;
• sealing means for sealing between the rigid cup and the penis when the penis head is inserted for preventing or hindering air from entering the cup or entering a region between the cup and the penis head;
• and
• a push/pull actuator configured to be coupled to the rigid cup and operable to move the cup together with the inserted penis head reciprocally back and forth;
• the coupling means and the sealing means being configured to obtain in use a vacuum lock effect between the rigid cup and the inserted penis head for substantially locking the penis head to the cup to so that the penis head is forced to move along with the cup upon push/pull movement.
