From Britain’s Daily Mail tabloid:
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. ‘Pre-birth exposure to both nicotine and amphetamines increases the chance of lesbian daughters,’ said Swaab. ‘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,’ Swaab said reported The Sunday Times. The development of the brain is such a delicate process during pregnancy that Swaab believes any small changes can have a major impact on a person’s life. A key example of this was in a study which found that women who took the synthetic estrogen DES when pregnant were more likely to have daughters with bisexual or homosexual tendencies.
