Say What!! Smoking during pregnancy increases your child's chances of being gay-Research claims

Ladies get in here .A controversial new study claims that decisions made by women when they are pregnant can affect their babies brains including determining their sexuality, intelligence and chances of developing autism.
The suggestion that the lifestyle of an expectant mother can affect their offspring's development has  been put forward in Professor Dick Swaab's new book We Are Our Brains.
The professor of  neurology at Amsterdam University claims that the chance of having a child who is gay can be determined by a range of factors including how stressed pregnant women are as well as whether they smoke and their exposure to amphetamines.
'Pregnant women suffering from stress are also more likely to have homosexual children of both genders because their raised level of the stress hormone cortisol affects the production of foetal sex hormones,'
Research has previously found that boys with older brothers are more likely to be homosexual than those with sisters, younger brothers or no siblings at all.
For every older brother a man has, the chances of him being gay increases by 33 per cent, according to Canadian psychologist Ray Blanchard.
