Marketers offer many different types of nonsurgical penis enlargement, and often promote them with serious-looking advertisements that include endorsements from “scientific” researchers.

But if you look and read closely, you’ll see that claims of safety and effectiveness are groundless. No reputable scientific research validates any type of nonsurgical penis enlargement, so marketers rely on testimonials, skewed data and before-and-after photos that often aren’t authentic.

At the bottom of such advertisements, you’ll usually find a sentence such as “These statements have not been evaluated by the Food and Drug Administration (FDA).” Indeed, the FDA, the government agency that regulates medications and medical devices, has never approved any medications or devices for enlarging a penis.
