We hear many different theories from our friends about how to make sure you have a boy or girl, but here is an article that has a little different twist to it!
In an article written in Medical News Today, researchers looked at a change that has been occurring over the last few decades related to the ratio of boys to girls born each year. Around the world there are consistently more boys than girls born, however in industrialized countries the gap between the number of boys and girls born is closing. A professor of reproductive epidemiology in Sweden began to wonder if there were factors that were causing the change in numbers.
One thing he found, was that mothers who gained weight between their first and second pregnancy were more likely to give birth to boys. - He cautions folks not to intentionally gain weight in hopes of having a boy though. ![]()
Why he wondered? Since his findings were consistent among many countries including Canada, Denmark, England, Germany, Japan and the United States, it couldn’t be concluded this trend could be blamed on the obesity problem here in the United States. Also, the findings didn’t seem to change when factoring in obstetric complications, maternal smoking, the age of the parent, the total number of years between the first and second pregnancy or the sex of the first born child.
