Six times more likely to have high blood pressure later in life have children born by IVF than those born naturally, which increases the risk of heart attack, stroke or other cardiovascular problems. New Swiss scientific research, small-scale, is the first to make this correlation. But other scientists consider it premature to draw definitive conclusions.
The sample of researchers, led by Dr. Emmy Rexatz of the University Hospital of Bern, who published the journal in the American College of Cardiology, was 96 teenagers. What they found, was that eight of the 54 who were born with extracorporeal patients had clinically high blood pressure up to 16, compared to just 2.3% of those born without IVF.
Both mean systolic and mean diastolic pressure of extracorporeal children were higher than those of the remaining children.
“There is growing evidence that assisted reproduction affects children’s blood vessels, but long-term effects are not known. Now we now know that it can reduce the risk of hypertension, “said Rexadj.
The first “tube baby,” Louise Brown, is 40 years old today (celebrating her 40th birthday in July), so the effects of assisted reproduction have not yet been studied over a long period of time.
But other British scientists have pointed out the small size of the sample of the Swiss study and said the issue should be studied in a much larger sample of the population to confirm that it is indeed the way of birth with extracorporeal hypertension.
An earlier study in 2014 had provided indications that IVF children are more at risk from type 2 diabetes due to their increased resistance to insulin hormone.
Approximately six million people living in the world who have been born using a method of assisted reproduction are currently counted. In any case, great clinical trials should be undertaken to better study the potential health risks over time.
