As with existing contraceptives, accountability can only extend to the product itself. If a woman forgets to take her contraceptive pill and falls pregnant, she cannot hold the pharmaceutical company liable. If a condom is not tight enough because of improper application, one cannot hold the condom manufacturer accountable. Similarly, users of the Bimek SLV cannot hold the manufacturer accountable, because of undermining the valve’s intended effect through misuse or because of not properly checking the desired sterility via a spermiogram.
