the most significant new method is probably a surgical one, the Penuma penis implant. Like silicone implants for female breasts, it gives a permanent legthening effect and is, and that’s the most important part, easily reversible. As far as non-surgical methods are concerned, there is a lot of research on stem cells to make new tissue grow in general. Maybe the future to make your penis bigger, but so far it’s more like science fiction, even far from an experimental stage.
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.
