A Dutch neuroscientist has warned that women who smoke and drink alcohol during their pregnancy have a higher chance of giving birth to children who may turn out to be gay.
The claim was made by Amsterdam University's Dr Dick Swabb in his new book 'We Are Our Brains' in which he cites multiple studies that show how an expectant mother's lifestyle affects her baby. one of the studies involved checking out the effect of synthetic oestrogen given to pregnant women between 1939 and 1960 to reduce the risk of miscarriages.

"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. Even in women who drink just a glass of wine a day we see effects [such as] lower IQ and hyperactivity. There is no safe level", Dr Swabb said.
