Abstract: A system and method of selecting a prophylactic for a body part, such as a condom for a penis. The system is run as a software application running on a handheld electronic device that contains an integrated digital camera. To operate the software application, a user selects a measurement standard having known dimensions. The measurement standard is positioned near the body part and a digital image is taken. Points along the periphery of the imaged body part are manually selected. From the selected points, the software application can calculate the distance between the points and size the body part. In the case of a penis, the length and girth of the penis can be readily calculated by the software application. Once the body part is sized, the software application uses the measured sizes to determine what prophylactic device would fit best. This information is communicated to the user.

Abstract: A loose fitting male condom which is held in place by a simple, yet reliable closure. The closure can be a continuous elastic band or a fastening strip. The loose fit makes application and removal easier, and during intercourse increases sensation for the wearer. The closure provides a seal at the base of the penis to protect from disease and pregnancy resulting from fluid leakage, and if suitably tight, can prolong erections.
