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.
The spermatozoon can easily pass through the 'net' that is formed by the condom.
For these reasons, HIV transmission within long-term serodiscordant relationships, especially heterosexual ones, may be rarer than it is between casual sex partners.
For all these reasons, large studies may be needed to establish differences in HIV (and HSV and HPV) incidence between condom users and non-users.
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 evidence we have is based on three types of trials, and each has potential weaknesses.
For efficacy against HIV and other chronic STIs, studies of the incidence of HIV (or HSV or HPV) in monogamous serodiscordant couples provides the best evidence.
The next problem is deciding what kind of study provides truly reliable evidence.
It would be unethical to mount a randomised trial of condom use because the control group would have to stop using them altogether.
Consistently used condoms provide significant protection against HIV, pregnancy and sexually transmitted infections (STIs).
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.
Laboratory studies and product testing have shown that reputable condoms tested in the laboratory are completely impermeable to micro-organisms as small as viruses.
