Abstract: A condom tester and applicator comprises a hollow cylinder (10) having an open proximal end (12) and a distal end (14). The hollow cylinder is constructed of a transparent material, such as clear plastic. The distal end of the cylinder possesses an end-face (16) which contains a one-way valve (18). The inner surface of the hollow cylinder accommodates a plurality of longitudinal grooves (22). A mounting flange (24) is formed at the periphery of the proximal end of the hollow cylinder. A condom is tested by sealingly installing it into the hollow cylinder and creating a pressure differential across the condom membrane by forcing out the air inside the cylinder through the one-way valve and thus distending the condom. The condom is donned onto a penis by inserting the penis inside the hollow cylinder with the condom inflatably installed therein, and transferring the hem ring of the condom from the mounting flange onto the base of the penis.
