An example stimulation device for stimulation of an area inside a human body includes a first portion configured to at least partially be inserted into the human body, a pressure field generation device configured to generate a pneumatic pressure alternating field, and a pressure chamber coupled with the pressure field generation device, the pressure chamber configured to accommodate a pressure alternating field generated by the pressure field generation device. The pressure chamber is disposed in the first portion and includes an opening formed in the first portion, the pressure alternating field in the pressure chamber to be applied via the opening to the area to be stimulated inside the human body.
