IVF may be a risk factor for diabetes
Researchers from the University of Adelaide in Australia have found that children conceived through in vitro fertilization may have an increased likelihood of developing type 2 diabetes as adults. As IVF rates have risen, so too have rates of diabetes, though the two have yet to be correlated in any meaningful way.
Using a study of IVF mouse eggs, embryos were transferred to mice to develop, mimicking how the procedure would be followed in humans. The offspring were weighed weekly from birth and at adolescence, and were given either a regular diet or a high-fat diet. When they reached adulthood, the risk of developing type 2 diabetes was evaluated, and glucose levels were measured, along with the ability to handle glucose ingestion. The scientists found that, regardless of diet, IVF male mice showed an increased risk for developing diabetes, where only the female mice that ate a high-fat diet exhibited this higher susceptibility.
This test is one of the first to evaluate how IVF translates into adulthood, and if there are any long-term consequences. The researchers acknowledge that much more research needs to be done on the matter.
