London - Women who smoke during pregnancy may damage their daughters’ chances of becoming mothers, a study warns.
Baby girls born to smokers showed signs of increased testosterone exposure, which may affect their hormone and reproductive function.
Smoking during pregnancy is widely thought to damage the health of mothers and babies, but cigarette smoke is believed to have properties that disrupt hormones and may increase testosterone levels.
Scientists at the Cigli State Training Hospital in Turkey examined 56 newborn girls and 64 newborn boys from mothers who smoked during pregnancy.
Physical markers the scientists found indicated "significantly increased" testosterone levels that correlated with the amount the mothers had smoked.
