Fertility Cliff: Is It Real?
Play episode · 43 min

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.

With the recent passing of Ruth Bader Ginsburg, there's been a lot of debate about how much power the Supreme Court should really have. We tend to think of the Supreme Court justices as all-powerful guardians of the constitution, issuing momentous rulings from on high. They seem at once powerful, and unknowable; all lacy collars and black robes. But they haven’t always been so, you know, supreme. On this episode of More Perfect, we go all the way back to the case that, in a lot of ways, is the beginning of the court we know today. Also: we listen back to a mnemonic device (and song) that we created back in 2016 to help people remember the names of the justices. Listen, create a new one, and share with us!
