Why you're less fertile than your grandparents were

Despite our population across the globe exceeding 8 billion, several reports say that the fertility of both men and women has been decreasing since the 1950s.

On this extra episode of The Briefing, we hear from fertility experts Dr Manuela Toledo and Professor Robert McLachlan, to find out whether you are less fertile than your parents or your grandparents were.
