One clue: in gay fathers, but not heterosexual ones, the brain also had extra communication lines between emotional and cognitive structures. The more time a man spent as primary caregiver, the greater the connectivity. It was as if playing both parental roles caused the brain to integrate the structures required for each.
I'm looking at the last paragraph in the OP quote and it says, "in gay fathers, not heterosexual ones" as if they studied both? Maybe gay fathers are more attuned to their feminine, nurturing side allowing for more of the emotional and cognitive structures suited for playing both parental roles?

Anyway, I wasnt aware that they had identified the hormones...do you have any links that show they believe it's estrogen? I understand that you said it's still being researched.
And have they identified any stage(s) during fetal development when they believe the hormones have affect/the most affect? I'd be interested in reading your sources.
I dunno, I'd imagine it depends on the gay guy. But I always find it a little funny when people attribute this to "femininity," given the very cold realism that many women usually face relationships and children with (and not without good reason -- they're the ones asked to give up everything). However, what we clearly see here is that neither normative role is balanced, and there's every possibility it's not natural either.
