The Mirror reports:
“The brain doctor suggests smoking and synthetic hormones can increase the likelihood of girls being lesbian or bisexual.
Poor lifestyle choices such as drinking alcohol or taking drugs while pregnant can lower a child’s IQ, claims Prof. Swaab.
He writes in the controversial book that brain development during pregnancy is altered by the tiniest chemical changes.
And if a woman has given birth to older brothers the chances of her baby being gay is greater.
