Even those penile extenders and stretchers that claim to work over time would actually just be stretching your flaccid length, and that has absolutely no correlation to how big you get when hard, says Fisch. So don’t waste your money on a product or service that swears it can give you five more inches. “There’s no actual scientific study that they rely on."
A new review in the journal Urology found that strengthening a man's pelvic floor—the muscles that surround the base of your penis and form a shelf across the bottom of your pelvis—can help diminish erectile dysfunction and premature ejaculation. How so? When you get hard, your pelvic muscles keep blood in your shaft. This helps to enhance and maintain your rigidity, says urological surgeon Andrew Siegel, M.D., the study's author and creator of pelvic floor exercise DVD Private Gym. And for premature ejaculators, squeezing those muscles can delay your orgasm. The stronger these muscles, the better the effect, Dr. Siegel says.
It seems every guy either wants to tell you how huge his penis is, or make it bigger than it is. And there are lots of methods out there that claim to be able to help. From drugs and supplements to devices and injections and even surgery, there’s lots of options to make your penis grow. But do they actually work, and are they something you want or need to get involved in?
The vacuum pump. This is a cylinder that sucks out air. You stick your penis in and the resulting vacuum draws extra blood into it, making it erect and a little bigger. You then clamp off the penis with a tight ring -- like a tourniquet -- to keep the blood from leaking back into your body. What are the drawbacks? The effect only lasts as long as you have the ring on. Using it for more than 20 to 30 minutes can cause tissue damage. This is sometimes used as a treatment for erectile dysfunction, but has not been proven to actually increase the size of the penis.
