RScientists believe that miscarriages that occur can be caused by an underlying infection, while they have launched a major trial to determine if the problem can be solved with simple antibiotic treatment.
Every year, in England and Wales, about 14,000 couples experience at least two consecutive miscarriages, but the reason is unclear.
Researchers at the University of Warwick and Coventry University Hospital found that the uterine lining of women who continued to miscarry was inflamed, a condition called endometritis.
Several countries, including Germany and the United States, already recommend antibiotics for endometritis, which can cause bleeding and pain, but no test has proven that it was an effective treatment against miscarriages.
At present, British scientists have received 1.9 million pounds from the Council for Medical Research and National Institutes of Health, the health branch of the NHS, to find out if the drug could work.
