Fertility Cliff: Is It Real?

We’re often told to have kids quickly, before our biological clock strikes and we fall off the fertility cliff. This week we find out if that’s true for women or men. And if the cliff is real, can you do anything about it, like freezing your eggs? Plus, the sperm-aggedon! We speak to epidemiologist Prof. Lauren Wise, reproductive endocrinologist Dr. Mary Sabatini, and andrologist Prof. Allan Pacey. UPDATE 7/10/19: A previous version of this episode incorrectly identified the nationality of a character in Indiana Jones. The episode has been updated accordingly. Check out the full transcript here: http://bit.ly/35DfLE8 Selected references: Lauren’s two studies looking at the fertility cliff. Click here if you want to be in one of her studies!
