Conclusive evidence from studies of serodiscordant couples (where one partner is HIV-positive and the other is not) shows that using a condom reduces the probability of HIV
transmission during penetrative sex by about 90%. Thus, the best estimate that may be deduced from all these studies is that condoms used correctly and consistently reduce the risk of transmission by about 90%.
