The womb is the small, hollow, pear-shaped organ in a woman's pelvis. This is the organ in which a baby grows. Also called uterus.

Maternal signals help synchronize babies’ circadian rhythms before birth

Humans and most other organisms have internal biological clocks that track the daily cycle of sunrise and sunset. These clocks help time our sleep, metabolism and other essential body functions over the course of a day, creating daily patterns called circadian rhythms.

Low birthweight increases stroke risk independent of adult BMI

In new research to be presented at this year's European Congress on Obesity (ECO2026) in Istanbul, Turkey (12-15 May), researchers show an increased risk of stroke in young adulthood for children of low birthweight, independent of their body mass index (BMI) as young adults or gestational age at birth.

New brain atlas reveals how the human neocortex forms over time

In a bid to better understand, and potentially treat, a host of conditions that affect early cognition, neurodevelopment and the brain later in life, investigators at Johns Hopkins Medicine and colleagues throughout the world have been mapping the molecular construction of the human brain.

Study connects ultra-processed diets to fertility and embryo development

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early embryonic development, according to new research.

Early prenatal shunt treatment improves outcomes for fetal megacystis

An interdisciplinary team from the University Hospitals Cologne and Bonn have conducted the first prospective study to investigate whether very early intervention in unborn children with congenital lower urinary tract obstruction (cLUTO) can improve their chances of survival and subsequent kidney function.

Maternal antibodies protect newborns from severe E. coli infections, study finds

A multi-center study led by researchers at Cincinnati Children's sheds surprising new light on why some newborns become severely ill from Escherichia coli infection, but others do not.

Decoding the purpose of fetal yawns in the womb

Even in the womb, where all oxygen is provided by the parental placenta, fetuses can-and do-yawn. More yawns during observation were associated with a lower weight at birth-potentially indicating mild fetal stress in the womb, according to a study published February 25, 2026 in the open-access journal PLOS One by Damiano Menin, of the Università degli Studi di Ferrara in Italy, and colleagues.

Prenatal infection increases risk of alcohol misuse in adulthood

Exposure to infection and other immune stress in the womb increases the likelihood of alcohol misuse in adulthood, a risk that may be reduced through prenatal antioxidant treatment, a new Washington State University study shows.

Hormone replacement therapy shows no rise in overall mortality

Menopausal hormone therapy (commonly known as hormone replacement therapy or HRT) is not associated with an increased risk of death, finds a Danish study of over 800,000 women published by The BMJ today.

MRI scans reveal human brain growth from pregnancy through birth

Analyzing brain growth across pregnancy and early life, this study offers new insights into sex-specific development and its implications for neurodevelopment.

Study explores how shared cells influence health across generations

During pregnancy, maternal and fetal cells migrate back and forth across the placenta, with fetal cells entering the mother's bloodstream and tissues.

Natural ovulation matches hormone therapy success in frozen embryo transfer

Natural ovulation before frozen embryo transfer is as effective as hormone treatment for achieving a healthy baby by vitro fertilization (IVF), finds a clinical trial from China published by The BMJ today.

Engineered womb lining model opens a window into embryo implantation

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and Stanford University have been able to study the implantation of human embryos, opening up this enigmatic process to investigation.

Study finds no specific harms linked to hydroxyurea exposure during pregnancy

Taking the sickle cell drug hydroxyurea during or shortly before pregnancy does not appear to cause specific issues in newborns, according to the first prospective study of pregnancies involving hydroxyurea exposure.

Maternal exposure to fatty food aromas predisposes offspring to obesity

A research team at the Max Planck Institute for Metabolism Research has found that the smell of fatty foods during pregnancy increases the risk of overweight and obesity in children.

Researchers use organoids to study the earliest moments of electrical activity in the brain

Humans have long wondered when and how we begin to form thoughts. Are we born with a pre-configured brain, or do thought patterns only begin to emerge in response to our sensory experiences of the world around us? Now, science is getting closer to answering the questions philosophers have pondered for centuries.

New Cochrane reviews confirm the effectiveness of HPV vaccines in preventing cervical cancer

Two new Cochrane reviews show strong and consistent evidence that HPV vaccines are effective in preventing cervical cancer and pre-cancerous changes, especially when given to young people before they are exposed to the virus.

Maternal stress linked to earlier baby teeth

Children have 20 milk teeth, 10 in each jaw. This set of teeth is important for chewing and speaking, and helps to keep space open for the subsequent set of 32 permanent teeth.

Schizophrenia risk detectable at birth through epigenetic signatures

Genetic susceptibility to neurodevelopmental conditions such as schizophrenia, autism, and ADHD can be linked, in part, to distinct epigenetic signatures in newborn cord blood.

New WHO guidance aims to strengthen care for preterm and low birth-weight babies

The World Health Organization (WHO) is marking its first official observance of World Prematurity Day with the launch of a new global clinical practice guide for Kangaroo Mother Care (KMC) – a simple, proven and life-saving intervention that significantly improves survival for preterm and low birth-weight babies.
