A review of studies comparing non-latex with latex condoms has been produced based on the results of 11 trials on heterosexual couples, nine in the USA, one in the UK and one in France.
The non-latex condoms were made of polyurethane or a synthetic polymer. Most of them were coated with a silicone-based lubricant. The analysis focused on the risk of the condom breaking or slipping during vaginal intercourse.
The condom broke during the sex act in 3.8% of cases compared with only 0.8% with latex condoms.
The condom slipped off the penis in 1.5% of cases for both types of condom. Most of the trials did not report any adverse effects.
Condom users should be informed that condoms sometimes break during sex: in around one out of 120 cases with a latex condom, and one out of 26 with a non-latex condom.
It is advisable to take the time to put on the condom properly taking care not to damage it, stretch it or trap air in the tip; only a water-soluble lubricant should be used.
