A penile prosthesis (100) is provided, which includes at least one cylinder (112, 114), a reservoir (118), and a pump (116) including a pump housing, at least one reservoir channel (124) fluidly coupling the pump housing to the reservoir, at least one cylinder tube (120, 122) fluidly connecting the pump housing to the cylinders, a fluid passageway fluidly coupled to the reservoir channel and a transfer chamber, wherein the transfer chamber is fluidly coupled to the at least one cylinder tube, and a bypass chamber comprising bypass input and output channels and a bypass check-valve biased towards a closed position. The pump also includes a pump bulb fluidly connected to the fluid passageway between the bypass input channel and the bypass output channel along the length of the fluid passageway. Also disclosed is a pump for transferring fluid between a reservoir and at least one cylinder within a penile prosthesis.
