When used properly, condoms provide excellent protection against sexually transmitted infections (STIs) and unintended pregnancies [1]. Non-use of condoms is the major risk factor for transmission of STIs, far overwhelming condom failure (slippage or breakage) or transmission of infectious agents through the latex barrier [2]. To increase acceptance and usage, condoms are manufactured and marketed in a variety of shapes, textures, colors and flavors. However, there are significant limitations imposed upon the sizes of condoms made available, and several recent studies highlight public health problems with current condom sizes and the need to expand the range of sizes [3–5].
