[Artificial penile nodules (tancho nodules) in Southeast Asian men].

Especially in Thailand, but also in other countries in Southeast Asia, the practice of implanting glass or other kinds of beads in the subcutaneous tissue of the penis for the purpose of increasing the sexual pleasure of the partner has become common. The inserted glass beads do not usually give rise to symptoms and normally they are only detected by chance. Here we describe our experience with a 27-year-old Thai with a penile nodule made from the polished material of a tooth brush.
