Simple op 'can double chances of giving birth'

A cheap and simple technique that involves scratching the lining of the womb could double fertility rates in women, research suggests.
A global study found that women who underwent the procedure during natural or assisted conception had birth rates 2.2 times higher than those who did not.
There has long been debate among fertility experts about the merits of performing an 'endometrial scratch', in which a tiny tube - smaller than a drinking straw - is used to disturb the womb lining.
The review, by Cochrane, an international group of medical researchers, examined eight trials involving more than 1,000 women and found that the procedure appeared to significantly boost birth rates among both women trying to conceive naturally and those undergoing treatment.
Experts are still unclear how the procedure improves pregnancy rates. One theory is that it helps the womb lining to shed dead cells, encouraging new ones to grow.
Another is that the inflammation caused by the disruption makes the lining more receptive to embryo implantation.
