NEW YORK (Reuters Health) – Thousands of children born every year through so-called IVFs may be at risk of asthma, according to a recent scientific study.
According to the website of the Daily Mail, the researchers found that IVF increased the risk of asthma in children by 22%.
Scientists from the Norwegian Institute of Public Health, who have followed more than 500,000 children, believe that drugs given to mothers during IVF may cause asthma in their children.
They said the way embryos are handled and manipulated before they are implanted into the womb may also play a role in asthma.
More than 8 million children worldwide have been born through IVF since technology pioneered in Britain 40 years ago.
In the UK alone, 20,000 children are born every year using IVF, and in the United States, 60,000 people.
