Mother’s Diet Could Influence Baby’s Gender

A study suggesting that a mother’s diet can help determine the sex of her baby meets skepticism, and raises ethical concerns.
30-Second Summary
Researchers studied 740 first-time pregnant mothers in the United Kingdom and learned that those who consumed a greater amount of calories around the time of conception gave birth to more male babies.
The incidence of male births was also higher in women who ate at least one bowl of cereal a day.
Scientists say the study could explain why the number of male births in developed countries has fallen during the last four decades; dieting is common in such places, and many women of childbearing age skip breakfast.
Scientists learned from research about in vitro fertilization that high levels of glucose help male embryos to grow and develop.
Some doctors, though, say the correlations drawn in this study are “spurious” at best, because the father’s sperm determines the gender of a child.
Others say the findings could just add to the toolbox some people are using to create “designer babies.”
Ethicist Nigel Cameron, president of the Institute on Biotechnology and the Human Future at the Chicago-Kent College of Law at the Illinois Institute of Technology, said, “We need a lot more social debate about the fact children should be received as-is.”

A study of 740 pregnant mothers in Britain has yielded the first evidence that a mother’s diet around the time of the conception of her baby could influence the child’s gender. Researchers noted that 56 percent of women with a higher caloric intake had a boy, while only 45 percent of women with a lower caloric intake had a male baby.

Scientists had mothers-to-be track their diets before conception and during the early stages of their pregnancies. In addition to high-calorie diets, mothers who ate breakfast cereal seemed to have a higher chance of bearing a male baby. Research about in vitro fertilization has shown that high levels of glucose help male embryos to grow and develop.

Opinion: Diet or biology?
Critics say the new study contradicts basic human genetics because the father’s sperm determines the gender of a baby. Dr. Paul Magarelli of the Pacific Coast Reproductive Society said that the correlation between mothers’ diets and male birth rates is “spurious.” However, animals have displayed similar trends. For example, horses, cows and some deer species give birth to more males if the mother has more nutritional resources.

Some U.S. parents are using pre-implantation genetic diagnosis (PGD) to choose the sex of their child. The process was initially created as a way to distinguish healthy embryos from those predisposed to genetic diseases during in vitro fertilization. Not everyone approves of using PGD for gender selection.
