The condom itself is not 100 % safe. Result of examination show the
following :

A condom is made of rubber (latex), a hydrocarbon compound with
polymerization, which means that it is fibrous and porous like woven
cloth. By means of an electronic microscope the pores of the condom can be
seen in a non-stretched state with a width of 1/60 micron, while the
HIV/AIDS virus has a width of 1/250 micron. When the condom is stretched
the pores of the condom are 10 times as wide as that of the virus; in
other words, the virus can go through the wall of the condom. The condom
was designed for family planning (to strain sperm, not viruses); and a
condom is not meant for fornication/prostitution.

Research carried out in the U.S. on 89 condoms in circulation on the
market proved that 29 out of 89 leaked, which means that the leakage was
about 30 %. In Indonesia condoms imported from Hong Kong in 1996 were
withdrawn from market because 50 % leaked. In practice in the field there
is often failure of condoms use for family planning because of leakage,
let alone for fornication/prostitution. As a comparison, sperm are as
large as oranges and viruses as large as a period (dot).

Another examination conducted in the U.S. ( the Physical Division of Human
Sciences, Maryland, USA, 1992) showed that particles as minute as viruses
can be detected going through the wall of condoms.
In every condom there are 0.4 % pinhole, microscopic defect in the
manufacturing process. The area of the condom is 80 cm2 and if you count
32,000 pinhole in each condom, and if each pinhole is 1/1000 micron, you
can imagine the total number of pinholes in a condom.

Based on the above finding, the anti-AIDS campaign in the U.S. no longer
uses the Safe Sex Use Condoms slogan, but just the reverse (a turn of
180o),

At the same time an expert of the University of Utah, Professor Victor
Cline, state in 1995 that if we believe that by using condoms we are
protected from sexually transmitted diseases including the HIV/AIDS virus,
we really have gone astray.
