While all the talk these days is about the Iraqi war, there are plenty of ex-servicemen from the first conflict who are still counting the cost.
Many have either become infertile or are having problems starting a family, researchers have discovered. The servicemen's sperm quality has been affected by 'Gulf War syndrome', the toxic overload - mainly from vaccinations - that they were exposed to during the 1990-1 conflict.
In follow-up research among 42,818 participants, made up of veterans and non-veterans alike, the veterans reported more problems with starting a family. Some were taking longer than normal, while others were infertile, compared with those who had not served in the Gulf.
The research team, from the London School of Hygiene and Tropical Medicine, said the differences were too small to draw definitive conclusions, but they were worthy of further monitoring.
