Abstract

As early as 1931 McKenzie designed an artificial vagina for the collection of boar semen. For convenience, it will be referred to as the Type A vagina. It consists of a soft rubber tube, 16 in. long, one end of which is fitted over the mouth of a test tube. The other end is fitted over a 15/8 inch key-ring. An ordinary clamp completes the outfit. The rubber is band tubing, 13/16 in. inside diameter and 1 Y2 in. outside diameter.
