In common with many other developed regions, the USA has seen a downward trend in the number of children being born. According to the New York Times, supporters of president-elect Trump and some of his nominees are raising concerns about the lower birth rate and are calling infertility a 'crisis'.
US researchers say it is a difficult question to answer, but there are some health trends that are causing concerns. The nation's fertility rate is at an all time low, but the statistics do not differentiate between people who have decided not to have children and those who cannot conceive. Exposure to endocrine disruptors in common household products, obesity, and an increase in sexually transmitted infections have also been mentioned by researchers as possible reasons for a drop in fertility.
