A '''ball stretcher''' is a [[sex toy]] that is used to elongate the [[scrotum]] and provide a feeling of weight pulling the [[testicles]] away from the body. This can be particularly enjoyable for the wearer as it can make an orgasm more intense, as testicles are prevented from moving up. Intended to make one's testicles hang lower than normal (temporarily or, if used regularly for extended periods of time, permanently), this sex toy can be potentially harmful to the genitals as the circulation of blood can be easily cut off if over-tightened.

Most ball stretchers are leather, rubber, or stainless steel. Leather ones usually are fastened with snaps, wrapping around the scrotum with the testicles hanging below. (See "Testicle Cuffs" below.) Rubber ones stretch enough for the testicles to pass through, and can be either a tube or a ring, where multiple rings can be added to create the desired length of "stretch". The length of a stretcher can range from {{convert|2|to|10|cm|abbr=on|in|0}}.<ref name="Hartley2006">{{Cite book

 }}</ref> Steel stretchers often use weight in addition to, or instead of, a physically restricted tube, to hold the testicles away from the torso. Steel weights need to come apart in order to fasten them securely around the scrotum. The removable segment might be held in place by friction, magnets, a set screw, or cap screws, and can range in weight from 150&nbsp;grams to 1200&nbsp;g or more. A more dangerous type of ball stretcher can be home-made simply by wrapping rope or string around one's scrotum until it is eventually stretched to the desired length.
