Hegar Sounds are now available individually, for those who would like to try just one instead of purchasing a whole set. The Hegar Sound is a urethral dilator with each end a slightly different diameter. The purpose of the sound is to gradually and gently enlarge the urethra using a smooth metal shaft that is inserted into the penis. Urethral play can be an adventurous new facet of your medical fetish or BDSM scene.

Measurements: 8 inches long, one end is 6 mm (0.3 inches) in diameter, opposite end is 5 mm (0.27 inches) in diameter

Material: Chrome Plated Brass

Please be well informed before you attempt this kind of play.  It is very important that everything is sterilized and that you use a sterile water based lubricant.
