Some men seek injections of natural and synthetic fillers to increase the girth of the penis. Others seek surgery if a smaller penis size or penile abnormality (like hypospadias) is interfering with the ability to urinate or quality of life. Small penis size usually is not an indication for surgery to treat infertility. In such cases, assisted fertility procedures may be the better option.
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.
