Effects of maternal exercise on fetal breathing movements

Researchers found that maternal exercise was associated with increased fetal breathing movements and improved fetal heart rate variability. Fetal breathing movements are a marker of fetal well-being and reflect functional development of the respiratory system and central nervous system control.

Fetal heart rate yields clues to children's later development

A new study found that fetal heart rate patterns before birth can predict children's mental, motor, and language abilities through toddler years. Greater variation in fetal heart rate was associated with better performance on standardized developmental exams and more proficient language skills.

Congenital diaphragmatic hernia

Research suggests that congenital diaphragmatic hernia does not disrupt pulmonary surfactant maturation in human fetuses, contrary to previous findings. The study provides new insights into the development of this complex condition.

Pitt study notes decline in male births in the US and Japan

A study published in Environmental Health Perspectives reports a significant decline in the number of male births in the US and Japan over the past three decades. The researchers found that the decline is equivalent to 135,000 fewer white males in the US and 127,000 fewer males in Japan, with environmental factors such as prenatal expo...

Fetus heart races when mom reads poetry

A recent study published in Psychological Science reveals that fetuses can recognize their mother's voice before birth and prefer it after delivery. The research found that fetuses responded differently to their own mother's voice versus a stranger's, suggesting they were learning about language in the womb.

Fetal heart diagnosis doesn't always predict survival

Research from the University of Michigan found that even with prenatal diagnosis, infants with one or more risk factors have a significantly lower chance of survival. However, in utero diagnosis has led to more pregnant women receiving specialty care, resulting in a higher-risk group of patients.
