The sex of new babies is influenced by the mother's diet before she
conceives, a new study suggests. According to a survey of 740 British
mums to be, a high-calorie diet is more likely to lead to a baby boy in

The researchers are unsure of why this happens, although they suggest
that it could be to do with levels of glucose in the blood. Male

to survive in the lab — Mathews suspects that a similar process may
operate in the uterus, so women with higher sugar levels are more
likely to nurture a male embryo as it is implanted in the womb lining. [Nature News]
