There have been plenty of studies of condom failure breakages, slipping off, etc. For instance, a Dutch study 26 of gay men, one-third of them HIV-positive, found that the overall failure rate during male-to-male anal sex was 3. The failure rate with the use of water-based lubricants was 1.
However in the yearresearchers from London's City University presented a study 2728 of gay male couples who had been randomised to use either standard or thicker condoms for anal sex and additional water-based lubricant. Each couple was provided with nine condoms and completed a questionnaire after each sexual act. The researchers marriage not dating ep 5 preview that condoms broke for the same reasons as previously identified in studies among heterosexual couples: Use of additional inappropriate lubricant oil-based or saliva was also associated with condom breakage.
Penis length was also associated with condom breakage, yet girth was not. The study found no significant differences between the two types of condoms with respect to breakage or slippage.
Condoms were more likely to slip if lubricant was placed on the penis under the condom. A low incidence of breakage was reported for both condom types during appropriate use.
The meta-analysis noted the direction of transmission male-to-female, female-to-male, and unstated and date of study enrolment. Condom usage was classified into the following three categories: To cite one of the 12 studies in more detail, 18 researchers looked at Italian serodiscordant couples in which the male partner was HIV positive.
Annual HIV incidence was 7. Davis and Weller subsequently published another meta-analysis in19 this time of 14 studies. The studies with the longest follow-up time, consisting mainly of studies of partners of haemophiliac and transfusion patients, yielded an HIV incidence estimate of 5.
In these nine studies there were only four seroconversions reported among 1. In contrast, when condoms were used inconsistently or not at all, of This is about the highest standard of proof we can expect from studies of condom efficacy.
