A wearable penile lengthening vacuum device, comprising a hollow body (2), which enables the
insertion of a
penis (1) without any problem, whereby both a part of the outer surface of a hollow body (2) and the proximal part (1a) of a
penis protruding from the hollow body (2) are wrapped in an airtight manner by the same highly elastic jacket (14) (a standard
condom (5) or a
silicone penis sleeve (6)), which thereby connects the penis (1) and the hollow body (2). The user can create a vacuum (lowered pressure) in the hollow body (2) by introducing a
tractive force on a pulling means (7) fixed to the sealed hollow body (2). An extension of the penis (1) will be caused by the continuous stretching effect of a continuously exerted
tractive force, as a large part of the
tractive force is (due to the vacuum resulting from this traction force) transformed into a
suction force, as the exterior air with
atmospheric pressure is prevented from penetrating into the hollow body (2). Said
suction force is evenly distributed on the tissue of the penis (1) surrounded by the vacuum.
