You are not the man your grandfather was - the shocking decline of sperm and testosterone

You are not the man your grandfather was. And that is not an insult. It is data.

This is not an episode about shaming modern masculinity. It is about understanding how bodies respond to modern life, why the data matters, and how to think clearly about male reproductive health without fear, politics, or pseudoscience.
