Dads are a lot more similar to moms than many of us realize. New or expectant fathers holding either their baby or a doll wrapped in their baby’s blanket experienced a rise in prolactin (a hormone usually associated with lactating mothers) and cortisol (a stress hormone associated with mothering) and a drop in testosterone. Also, when the men listened to a tape of a crying newborn and were shown a videotape of a newborn struggling to nurse, the ones who reported the greatest urge to comfort the baby were the ones whose hormone levels had changed the most.
Are there other hormonal similarities between the genders? Is male menopause a reality?
