Pitocin linked to Postpartum Depression?

I stumbled across this article on Facebook the other day and found it so interesting!  While I knew that synthetic oxytocin did not lead to endorphin production like natural oxytocin does (leading to a pain relieving effect as labor progesses) but I had no idea it reduced oxytocin production after birth too!  Click through to read the article, which links up the study as well!
