The degree of protection they offer against HIV and STIs is significantly better than any other single prevention method, taken in isolation, other than sexual abstinence or complete mutual monogamy between two people who have tested negative for HIV.

In one of the most highly publicised statements, in October 2003, the President of the Vatican's Pontifical Council for the Family, Cardinal Alfonso Lopez Trujillo, said: "The AIDS virus is roughly 450 times smaller than the spermatozoon.

The spermatozoon can easily pass through the 'net' that is formed by the condom.

In these circumstances, it is easy to see why condoms sometimes fail, even in consistent users.

In addition, however, people are not consistent in their use of condoms, and may not even be consistent when they claim to be, or think they are.

The main findings of studies we look at in more detail below are as follows: These degrees of protection may be lower than some readers expect, and rates of 98% reliability are still sometimes quoted for condoms.These are based upon observations of their use in contraception: studies have shown that 98% of women relying on condoms as their sole form of contraception remain pregnancy free if condoms are used perfectly, meaning that they are used consistently and correctly at every act of sexual intercourse.Another kind of study is to conduct a prospective cohort study, looking at differences in HIV incidence between two groups of people according to their usage of condoms.This cannot be a randomised controlled study, but participants’ HIV and STI incidence can be related to their condom use either at baseline or preferably (because behaviours change over time) by means of regular questionnaires and monitoring.The next problem is deciding what kind of study provides truly reliable evidence.
