ABSTRACT:
A method for testing a condom for viral penetration includes the steps of positioning a condom to be tested in a restraining device so that expansion of the condom is restricted to a size corresponding to the device anthropomorphic dimensions of a penis; pressurizing the condom via a liquid containing viral particles in suspension, and monitoring for passage of viral particles through the condom. The method which simulates conditions of human sexual intercourse while using a viral particle to test condom integrity can be effected using an apparatus with elements that are commonly found in a microbiology lab. The apparatus includes a conduit over which the open end of the condom to be tested is secured; a restrainer for restricting the expansion of the condom to a size corresponding to the mean anthropomorphic dimensions of a penis; a liquid containing viral particles in suspension, the liquid filling the condom; a pressurizing device for pressurizing the condom via the liquid; and a container filled with a collecting fluid wherein the condom and the restrainer are positioned so that the viral particles that have passed through the condom can be monitored.
