The male infertility crisis is an increase in male infertility since the mid-1970s. The issue attracted media attention after a 2017 meta-analysis found that sperm counts had declined by 52.4 percent between 1973 and 2011. The decline is particularly prevalent in Western countries such as New Zealand and Australia, Europe and North America, and has also been observed in non-Western countries such as China.
