Seems like you're conflating (in)fertility levels with fertility rate. Fertility rate has been dropping steadily, particularly in developed countries; however, this doesn't mean individuals are slowly all becoming infertile. In fact, studies have shown infertility rates have plateaued in recent decades, at least among women [1]. Fertility rates are dropping for different reasons--fewer individuals choosing to enter into long-term relationships and have kids, and families choosing to have fewer children on average than previous generations.
