  • Male Lactation May Have Been Conditioned Out of Humans

    In the book Sex Is Fun? by Jared Diamond, the author hypothesizes about the possibility that men don't naturally lactate because the desire to nurture their young has been conditioned out of their genetic code.

    If you're dying to see what the other half lives like and you don't want to wait around for a pituitary tumor, it turns out that all you have to do is play with your nipples a lot. Intense nipple stimulation naturally releases prolactin, the hormone that produces milk, and once there's enough of it in your system you never have to worry about whether or not you have half and half again. 

  • Charles Darwin Noted the Lactation Habits of Many Male Mammals

    Leave it to Darwin to blow the lid off this whole male lactation thing while he was also discovering evolution. In The Descent of Man, Darwin stated, "It is well known that in the males of all mammals, including man, rudimentary mammae exist. These in several instances have become well developed, and have yielded a copious supply of milk. Their essential identity in the two sexes is likewise shown by their occasional sympathetic enlargement in both during an attack of the measles." He further speculated that both sexes nursed their young in early stages of the Earth's development.
