AB Through use of a new bacteriophage assay capable of detecting a single
viral plaque-forming unit (PFU), viral leakage through multiple
replicates of several types of latex condoms has been evaluated. Stocks
were used that had been preserved from a previous large study in which
viral leakage had been assessed preliminarily in several brands. In the
present research, much larger numbers of replicates--on the order of
magnitude of 100 condoms per brand--were used. Leakage was demonstrated
in single production lots of each of seven brands of condoms. With one
notable exception, percent leakage ranged from 0.9 to 22.8%; 100% of the
specimens of one profoundly flawed brand leaked. All test condoms were
subjected to conditions intended to model these prevailing during
coitus. Because the condoms used in this study were aged, current stocks
of two widely sold brands were tested for comparison. Of these, 11.8% of
one brand leaked, 25.7% of the other. The relevance of the results,
which gave a high, albeit physiologically appropriate, challenge to the
test brands, is discussed--so too is the significance to condom users of
results deriving from a leakage assay of exquisitely high sensitivity.
