Tell me about sex
For Canada, the story is the same. A standard Health and Welfare Canada test of condoms manufactured between 1987 and 1990, based on stringent tests of pressure, leakage, and volume (as in the U.S., there is no effort to examine micron-level leakage), reported that an astonishing 40% of the
condoms tested failed at least one of the tests. Tests in 1991 showed an "improved" 28% rate.

The few statistics illustrating the effect of condoms use on HIV transmission in homosexual acts do not give clear cut results.
R.Detels (1989)lxxxix observed a 2.9% drop in seroconversion when condoms were used in homosexual intercourse, in a cohort of 2915 active homosexuals initally HIV sero-negative.
But, in that statistic, the number of partners for each member of the cohort was almost as important a factor as the use or not of a condom.
L.Levin et al. (1995)xc found that most (71%) of the 140 active-duty young men with documented sero-conversion who were identified in various US army installations did use a condom during their homosexual or heterosexual relations.
Results seemed to indicate a paradoxal increased risk of seroconversion proportional to condom use in this series.

Potent Carcinogen found in Most Condoms
Recent study has discovered the presence of a very potent carcinogen in most condoms. Small amounts of this chemical are released whenever condoms are used.
