Abstract: A multi-function measurement condom includes an indicia that enables the user to accurately measure his penis in its erect state, while simultaneously aiding in the prevention of pregnancy and sexually transmitted diseases. The condom is comprised of a tubular-shaped sheath with at least an inner layer and an outer layer of an elastic material, a dome-shaped closed end, and an opposite open end. A protrusion on the sheath extends lengthwise, and an indicia is placed between the inner and outer layers of the sheath. This creates a dual length unit with two different scale marks positioned adjacently, and the indicia extending centrally over the elongated protrusion. The indicia are visible through the outer layer so that the proper measurement can be deciphered by an individual. A niche located on the inner layer of the sheath incorporates the long protrusion into the rest of the apparatus smoothly, and it extends from the tip of the condom to a point short of its open end.
