Female reproductive cell development is the most vulnerable of all the organs, and women are not immune.
A new study in the journal PLOS ONE shows that, for some patients, having more than one daughter at the same time can lead to infertility, with one woman having multiple daughters and another having only one.
The findings add to a growing body of research showing that some women are at higher risk of having multiple children than others.
But even for those with no children, having multiple pregnancies may still lead to health problems, said lead author and postdoctoral researcher Toni A. Zuckerman, a senior research scientist in the Department of Epidemiology and Population Health at the University of Pennsylvania’s Perelman School of Medicine.
It can take up to five years to conceive, which is too long for most women, said Dr. Zuckerberg.
The results also are concerning, because many studies have suggested that having multiple births can have health consequences, said study co-author Jennifer T. Miller, an assistant professor of medicine at the Icahn School of Nursing at Mount Sinai.
It’s important to note that this study looked at a specific population, Miller said.
That’s a large group of women, and we wanted to see if it was really the case for women who were less likely to have multiple births.
The new study found that having more daughters at the time of conception may have negative health effects.
But having only two daughters did not seem to have an effect on the risk of infertility, Zuckberg said.
And having more sons may not lead to an increase in the risk.
However, having fewer daughters and more sons did increase the risk for infertility.
There’s no known reason for why more daughters and fewer sons would increase the rate of infertility.
And it’s unclear why the more sons increase the risks of miscarriage, Miller added.
So what can women do to lower their risk of developing multiple births?
The best way to do that is to have a normal, healthy pregnancy, Miller advised.
The best way, she said, is to avoid having a baby when you have fertility problems, especially if you’re in your 30s or 40s.
