Penis-enlargement products: Do they work?

Tempted by products that claim to increase penis size? Get the facts about what to expect from male-enhancement pills, pumps, exercises and surgeries.

By Mayo Clinic Staff

Ads for penis-enlargement products and procedures are everywhere. Many pumps, pills, weights, exercises and surgeries claim to increase the length and width of your penis.

But, there's little scientific support for nonsurgical methods to enlarge the penis. And no trusted medical organization endorses penis surgery for purely cosmetic reasons.

Most of the techniques you see advertised don't work. And some can damage your penis. Think twice before trying any of them.

Penis size: What's normal, what's not?

The fear that your penis looks too small or is too small to satisfy your partner during sex is common. But most men who think their penises are too small actually have penises that are considered typical size.

Many men also have an exaggerated idea of what is considered a "typical" penis size.

The length of a non-erect penis doesn't consistently predict length when the penis is erect. If your penis is about 5 inches (13 cm) or longer when erect, it's of typical size.

A penis is considered small only if it measures less than 3 inches (about 7.5 centimeters) when erect. This is a condition called micropenis.

How partners view penis size

Advertisers would have you believe that your partner cares deeply about penis size. If you're concerned, talk to your partner.

Understanding your partner's needs and desires is more likely to improve your sexual relationship than changing the size of your penis.
