There is no such thing as a tampon for men. By definition, a tampon is a feminine product designed to help absorb menstrual blood, according to Dictionary.com. Men have no need for such a product, and as such, no tampon for men has ever been manufactured commercially.
Tampons are created by a number of different brands, including Tampax, Kotex and Playtex. These brands all create tampons in standard sizes of absorbency, which are light, regular, super, super plus and ultra, according to Tampax. If kept in the body for too long, tampons can cause toxic shock syndrome, as noted by Mayo Clinic. The larger the size of the tampon is, the greater the risk for toxic shock syndrome.
