is an herbal nutritional supplement claimed to promote "natural male enhancement", which suggests a euphemism for penis enlargement. However, television commercials make few definitive claims, employing suggestion and euphemism or promising a "better" or "more fun" sexual experience. Websites selling the product make several more detailed claims, including acquiring a "larger penis". There, enlarging effects are described as "temporary", implying simply the achievement of an erection. Marketing may thus seem to be both oriented to erectile dysfunction, and to attracting na�ve purchasers seeking permanent enlargement of the penis. Early infomercials featured a studio audience and porn star (Pornographic actor) Ron "The Hedgehog" Jeremy (Ron Jeremy). Former Dallas Cowboys head coach (head_coach#American_football) Jimmy Johnson (Jimmy Johnson (American football coach)) has also appeared in an ExtenZe commercial.
