Being born even slightly premature might still raise a child's risk of developmental problems, a new study finds.
Preemies often have developmental issues, but previous research has tended to focus on those born extremely preterm (22-26 weeks' gestation), so less is known about children born moderately and very preterm (27-34 weeks' gestation). Average full-term gestation time is 39-40 w...
The growth patterns of kids born through fertility treatment differ initially from those conceived naturally, but those growth rates do catch up over time, a new study finds.
In-vitro fertilization and other forms of "assisted reproductive technology" (ART) has long been associated with lower birth weights in babies, but it wasn't clear how long differences in growth continue.
In what doctors call a breakthrough, a cancer patient in France gave birth to the first baby conceived from an immature egg that was matured in the laboratory, frozen, then later thawed and fertilized.
"We were delighted that the patient became pregnant without any difficulty and successfully delivered a healthy baby at term," said team leader Michaël Grynberg, head of reproduct...
Birthdays are a time of celebration. But, according to a new study, a spring or summer birth date could mean a higher risk of dying from heart disease.
The reasons aren't clear, but might include factors such as seasonal fluctuations in diet, air pollution levels, and the availability of sunlight before birth and in early life, the study authors said.
No, you're not seeing double as often these days: After decades of rising, twin births are declining in the United States.
Twin birth rates had been on the rise for 30 years, but dropped 4% between 2014 and 2018, health officials said in a new U.S. government study. That's the lowest level in more than a decade. In 2018, there were 32.6 twins for every 1,000 U.S. births.
More than 20 million babies are born across the globe weighing far less than they should, and the problem isn't limited to low-income countries, new research shows.
In 2015, nearly three-quarters of infants with low birth weight (less than 5.5 pounds) were born in Southern Asia and sub-Saharan Africa. But low birth weights persist in high-income countries in Europe, North America, A...
