Imam ti i ja jedan link: http://www.righto.com/theories/condoms1.html

Citati:
" Risk of condom failure (breakage
or slippage) on a single occasion is estimated for four sexual acts
reported over 12 months by a sample of gay New York City men (n =
741)."

"A meta-analysis conducted on data from in vivo studies 
of HIV discordant sexual partners is used to estimate the
protective effect of condoms. Although contraceptive research
indicates that condoms are 87% effective in preventing pregnancy,
results of HIV transmission studies indicate that condoms may
reduce risk of HIV infection by approximately 69%. Thus, efficacy
may be much lower than commonly assumed, although results should
be viewed tentatively due to design limitations in the original
studies. "

Dakle onako na pamet sa procjenom od 70% efikasnosti sam bio jako blizu
znanstveno dobivenim podacima.

"The test couples were generally quite experienced in the
use of condoms. It appears that the condoms rarely (1.3%) ruptured
or slipped off during the actual intercourse. This means that
emphasis must be put on consistency and skill in the use of condoms
rather on technical improvements in the promotion of condoms as a
means of preventing the spread of sexually transmitted infections
like HIV. "

"A suspension of fluorescence-labeled, 110-nm
polystyrene microspheres models free human immunodeficiency virus
(HIV) in semen, and condom leakage is detected spectrofluoro-
metrically. Leakage of HIV-sized particles through latex condoms
was detectable (P less than 0.03) for as many as 29 of the condoms
tested. Worst-case condom barrier effectiveness (fluid transfer
prevention), however, is shown to be at least 10(4) times better
than not using a condom at all, suggesting that condom use
substantially reduces but does not eliminate the risk of HIV
transmission."

"The studies, conducted two years apart, compared the
breakage rates of condoms from the same lot during human use to
their performance in laboratory test results. Breakage rates of
12.9% for Barbados, 10.1% for St. Lucia and 6.7% for the United
States compared to passing ASTM laboratory tests suggest that
existing laboratory tests as used with the current pass/fail
standards are either not sufficiently sensitive or not well-defined
to reliably predict condom performance during human use. The study
also suggests that user behaviors and practices may be a factor in
condom breakage."
