4D scans show fetuses yawn in the womb

Fox News: Growing into a fully formed human being is a long process, and scientists  have found that unborn babies not only hiccup, swallow and stretch in the womb,  they yawn too.

Researchers who studied 4D scans of 15 healthy fetuses also said they think  yawning is a developmental process which could potentially give doctors a new  way to check on a baby’s health.

While some scientists have previously suggested that fetuses yawn, others  disagree and say it is nothing more than a developing baby opening and  stretching its mouth.

But writing in the journal PLOS ONE on Wednesday, British researchers said  their study was able to clearly distinguish yawning from “non-yawn mouth  opening” based on how long the mouth was open. The researchers did this by using 4D video footage to examine all the times  when fetuses opened their mouths.

Nadja Reissland of Durham University’s department of Psychology, who led the  study, said the function and importance of yawning in fetuses is still unknown,  but the findings suggest it may be linked to fetal development and could provide  a further indication of the health of the unborn baby.

“Unlike us, fetuses do not yawn contagiously, nor do they yawn because they  are sleepy,” she said. “Instead, the frequency of yawning in the womb may be  linked to the maturing of the brain early in gestation.”

The study was carried out on eight female and seven male fetuses from 24 to  36 weeks ( 6 to 9 months old) gestation. The researchers found that yawning declined from 28 weeks  and that there was no significant difference in how often boys and girls  yawned.

I’m sure Planned “Parenthood” will not be posting this video on their website.  After all, “most women feel relief after an abortion.”

I think it’s amazing that we can see the development of a child, thanks to amazing technology!
