English: In these images is demonstrated how penis size and appearance change after use of a penis pump.

The male (age 35) seen in these images has no previous history of penis pump use. The left image shows male's penis in normal erect state, the right image is taken 15 minutes after use of a penis pump (10 minutes of use, male's 4th day of pumping). The penis after pumping is slightly longer and thicker (both in flaccid and erect state) but the influence diminishes over time. It is claimed that if the penis is pumped regularly in long-term the size enhancement will become permanent but there are no scientific evidence.

The penis seen in these images is originally about 19 cm or 7.5 inches in length (both stretched flaccid and erect length, measured from the pubic bone), at the time the right image was taken the length was about 20.5 cm or 8 inches.
