This post is a reprint of
a
post by Jad Abumrad & Robert Krulwich that originally
appeared at WNYC's Radiolab.

Our new season is just a little over a month away, so we decided to give everyone a teaser of what’s to come. This season, we devote a whole hour to the topic of “Sperm” … And if you think you learned all there is to know about sperm from that junior high school filmstrip, think again.
In today’s podcast, we give you two short pieces that hint at the new ideas and amazing stories we came across once we started following the trail of this wriggly little cell. First, in a twisted tale of twisted tails, fertility specialist Joanna Ellington, cofounder of ING Fertility, gives Robert a guided tour of all the sperm that are doomed to fail. Then Tim Birkhead, a biologist at the University of Sheffield, tells Jad and Robert how a dead wood mouse completely upended the idea that it’s “every sperm for himself.”
And there are more amazing sperm tales to come! The full show will be released in November.
