We have the BEST time teaching our Breastfeeding 101 classes because they are filled with education, laughter and support.  Usually we get questions about milk supply, how to balance work and breastfeeding, what a mamma can eat/drink while breastfeeding, etc.  But at last Saturday’s class one of the daddy’s had a question that, in the moment, but stumped Michelle and I and made us laugh.  He said, “You guys seem to be the experts on nipples, so why do men have them?”  We decided to do our research and answer this age old biological question…here is what we found cited from the Post Graduate Medical Journal:

Men have nipples because embryos are always female in their early stages, and males only differentiate from the female prototype after a few weeks.

So there you have it!  We also learned that with enough estrogen men can lactate…maybe that will lead to a whole new class in the future…hehe!
