Are couples turning too soon to In Vitro Fertilization? A question, recently published in the British Medical Journal, raised by Professor Siladitya Bhattacharya, academic of obstetrics and gynaecology at the University of Aberdeen. According to his research team, in fact, the risks could outweigh the benefits when IVF is expanded to a wider range of fertility problems. According to their data, indeed, 1 million babies were born in the first 25 years of IVF between 1978 and 2003. It took only two more years for the tally to reach 2 million in 2005, with over 5 million estimated to have been born by the end of 2013, their paper says. But the extended use of IVF can increase the risk of harm, they warn. Multiple pregnancies are associated with complications for mothers and infants, and even single babies born through IVF have been shown to have worse outcomes – higher blood pressure, body fat distribution (adiposity), glucose levels, and more generalized vascular dysfunction – than those conceived naturally. “Until these concerns are resolved, there should be caution about using IVF in couples when the benefit is uncertain or the chances of natural conception are still reasonable,” the authors say.
