The history of condoms goes back at least several centuries, and perhaps beyond. For most of their history, condoms have been used both as a method of birth control, and as a protective measure against sexually transmitted diseases. Condoms have been made from a variety of materials; prior to the 19th century, chemically treated linen and animal tissue (intestine or bladder) are the best documented varieties.
