According to Professor Dick Swaab from the University of Amsterdam smoking while pregnant can lead to a child being born gay.
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.
Prof Swaab writes in his book: “Pre-birth exposure to nicotine or amphetamines also increases the likelihood of lesbian daughters.
“Pregnant women suffering from stress are also more likely to give birth to homosexual children, because their raised levels of the stress hormone cortisol affect the production of fetal sex hormones.
“The more older brothers a boy has, the greater the chance that he will be homosexual.
“This is due to a mother’s immune response to male substances produced by boy babies in the womb, a response that becomes stronger with each pregnancy.”
Past studies of women who took synthetic oestrogen between 1939 and 1960 to reduce the harrowing prospect of a miscarriage had a greater chance of having daughters who were bisexual or lesbian.
