LONDON — A new study from an Amsterdam University neurobiology professor suggests that choices made during pregnancy such as taking synthetic hormones, smoking, drinking and stress can raise the chance of having a gay child, the Sunday Times reports.
Professor Dick Swaab says smoking, drinking and taking drugs designed to combat depression during pregnancy can lower a child’s IQ, while living in an area with high levels of traffic pollution can raise the risk of autism, the Times reports.
Swaab’s claims follow a survey of the latest academic studies about links between the lifestyles of pregnant women and the development of their babies. Each provides evidence of the sensitivity of the brain to outside influences, the article said.
“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 fetal sex hormones,” the Telegraph quoted him as having said.
