For decades after a woman has carried a male child in her womb or shared her mother's womb with a brother, she carries a faint but unmistakable echo of that intimate bond: male fetal DNA that lodges itself in the far recesses of her brain.

That astonishing finding, published Wednesday in the journal Public Library of Science One (PLoS One), suggests that the act of having a child is no mere one-way transmission of genetic material and all that goes with it: There is an exchange of DNA that passes into the part of us that makes us who we are. That, in turn, may alter a woman's health prospects in ways her own DNA never intended.

In the study, researchers from the Fred Hutchinson Cancer Research Center and the University of Washington examined, post-mortem, the brains of 59 women. In 63% of the brains, they found fetal DNA that could only have come from a male. While scattered throughout the brain, the genetic traces of this other individual were clustered heavily in the brain's hippocampus -- a region crucial to the consolidation of memories -- and in the parietal and temporal lobes of the brain's prefrontal cortex, areas that play roles in sensation, perception, sensory integration and language comprehension.

It's the reason why a dad shopping alone with a cute baby will get the attention of women in child bearing state, they see a healthy, good looking child and their instincts are that the dad has good seed.

I pointed this out to my wife a couple times when our kids were young, great way to get out of shopping and watching the kids.

It may be true. I never wanted to have children until after 4 years on the pill during marriage I became pregnant. It changed me and yes my first was a boy. The way he kicked and rolled this may be true. :laugh:

He he...

Way back when my ex and I were not ex's yet, I found that taking the boy [not my son] anywhere got me lots and lots of attention.....

My ex was not the jealous sort in any way so that kind of spoiled it.

If she is or not, she could have shown something to make you feel like a king.Men thrive off this.

Brain change link to anti-social behaviour in girls
21 October 2012 - Brain scans showed significant differences


The brains of teenage girls with behavioural disorders are different to those of their peers, UK researchers have found. The Journal of Child Psychology and Psychiatry study of 40 girls revealed differences in the structure of areas linked to empathy and emotions. Previous work has found similar results in boys. Experts suggest it may be possible to use scans to spot problems early, then offer social or psychological help.

An estimated five in every 100 teenagers in the UK are classed as having a conduct disorder. It is a psychiatric condition which leads people to behave in aggressive and anti-social ways, and which can increase the risk of mental and physical health problems in adulthood. Rates have risen significantly among adolescent girls in recent years, while levels in males have remained about the same.

Fear detector

In this study, funded by the Wellcome Trust and Medical Research Council, UK and Italian researchers conducted brain scans of 22 teenage girls who had conduct disorder and compared them with scans of 20 who did not. They also checked the scans against others previously taken of teenage boys with conduct disorder. The team found part of the brain called the amygdala was smaller in the brains of male and female teenagers with conduct disorder than in their peers.

The amygdala is involved in picking up whether or not others feel afraid - and plays a role in people feeling fear themselves. Girls with conduct disorder also had less grey matter in an area of the brain called the insula - linked to emotion and understanding your own emotions. However the same area was larger in boys with conduct disorder than healthy peers, and researchers are not yet sure why that is the case. The brains of those with the worst behaviour were most different from the norm.

did you ever think it was because those women thought you were old, comfortable, safe.
