Is Yawning in Utero Real?

Is yawning in utero real? The answer might surprise you. Yes, it does happen during pregnancy. But it also differs from your mouth’s opening in utero. You’re not the only one wondering if it’s real! The article below discusses the science behind it. Read on to learn how fetal acoustic stimulation affects intelligence. And remember that it’s not a “reality show”!

Artificial utero womb

An artificial utero womb may seem like a perfect solution for the booming need for alternative birth control. However, such a womb would have several challenges. One of the main ones is that it would be transparent, which would encourage greater intervention in the womb process. Another hurdle would be to successfully develop an artificial blood supply, which would connect the womb to the placenta.


For centuries, ectogenesis in utero was not considered a serious medical problem. Most women carried their pregnancies on their own with the support of friends, family and lay midwives. They believed that a warm, safe environment analogous to the womb would ensure the health of their child. Although childbirth was once considered a natural phenomenon, today medical advances have made it safer and more effective.

Yawning in utero

There has long been controversy over whether yawning in utero is real. Many people have wondered if it’s contagious and if it is sleepy. But new research suggests that yawning in the womb may be a real phenomenon and it could be a good indicator of the development of a fetus’ brain. Scientists at Durham and Lancaster Universities in the UK conducted a study to find out. Despite the conflicting results, the study highlights the importance of observing the fetus’s face movements during the womb.

Effects of fetal acoustic stimulation on intelligence

The effects of fetal acoustic stimulus on a developing child’s intelligence were investigated by examining PI responses, as well as cerebral circulation changes and afferent activity. PI responses are the result of changes in the fetal auditory system. PI values were measured in parous and nulliparous pregnant women and after defined auditory stimulation. The researchers also observed changes in the mother’s PI values, a measure of her cerebral circulation and function.

Developing a sense of balance in utero

In utero, the fetus develops a sense of balance. While tumbling in the amniotic fluid, the fetus is sensitive to its surroundings, such as sound and light. The mother’s movements, as well as the sounds and light she emits, stimulate the fetus’s ear. This helps the brain process motion and body position. By 25 weeks, the fetus displays a righting reflex and turns down before delivery.
