Some quack products may improve penis erection, mistaken by consumers for penis enlargement. Penile enlargement procedures are designed to increase the size of the cavernous cylinders of the penis or to stimulate blood flow to increase hardness. No complementary health approaches have been shown to be safe and effective for sexual enhancement or treating ED. Safety is a serious concern with regard to dietary supplements promoted for ED or sexual enhancement.
"The problem with injecting fat is that over time, the body will re-absorb it, which can result in a return to the penis' original size," he says. "Just like using lotions, this technique can help some men better appreciate the considerable difference in size between a flaccid penis and an erect one, which helps them become more comfortable with their body," says Professor Wylie. "But there's no scientific evidence to suggest jelqing can increase penis size." "There's some evidence that traction devices can have some impact, particularly with men who are smaller in size," he says. "Some patients using traction devices for 6 months have noticed a gain in size of 1-2cm. However, such treatments shouldn't be started without the supervision of a doctor."
