According to an aspect, an inflatable penile prosthesis includes a fluid reservoir, an inflatable member, and a pump assembly. The pump assembly includes a pump bulb, a valve body, a push valve movably coupled to the valve body, a first fluid port, and a second fluid port. The push valve includes a movable valve element configured to move between an inflation position and a deflation position within a bore of the valve body. The movable valve element in the inflation position defines a fluid passageway through the bore to transfer fluid from the pump bulb to the second fluid port. The movable valve element, when moved to the deflation position, is configured to change the fluid passageway through the bore to transfer fluid from the second fluid port to the first fluid port such that the pump bulb is bypassed.
