Why Do Men Fall Asleep After Sex?

Fri 16 Mar 2007 – 20.46

Oh, the question that has riddled women since the dawn of time. It’s actually pretty simple science:

Prolactin levels are naturally higher during sleep, and animals injected with the chemical become tired immediately. This suggests a strong link between prolactin and sleep, so it’s likely that the hormone’s release during orgasm causes men to feel sleepy.

So read the article, and next time you get mad at your fella for some dumb reason, remember that Biology beats Society every time.
