V-Y plasty is a surgical technique in which the suspensory ligament that anchors the penis to the pelvic bone is severed, releasing the shaft and allowing it to extend forward. The procedure is so named because it involves a triangular incision, the edges of which are pulled together and sutured in a "Y" shape. While effective in elongating the penis, it also makes the penis less stable when erect.
Stretching with weights. Weights or stretching exercises won't bulk up your penis -- it's not a muscle. But hanging weights off your flaccid penis may stretch it a bit, O'Leary says. The catch is that it requires a freakish degree of dedication. "You might have to wear a weight strapped to your penis eight hours a day for six months," says O'Leary. At the end of it, you could be lucky enough to gain about half an inch. Risks include tearing of the tissue, burst blood vessels, and other problems.
