Semen Science #100

February 25, 2011

This episode was recorded when Science for the People was called Skeptically Speaking.

Evolutionary biologist John Logsdon returns to explain the amazing diversity of sperm design, and its connection with mating behaviour. And Scientopia blogger Scicurious joins us to discuss some of our favorites from her Friday Weird Science archives. We'll talk about everything from the antidepressant properties of semen, to smelly semen, to testicle receptacles, and so very much more.

Here are links to all the Friday Weird Science posts that we discussed with Scicurious.
