Depression in early and mid-pregnancy seems to age the placenta more rapidly than not experiencing depression during pregnancy. Premature placental aging could account for higher rates of low birth weight, preterm birth, blood pressure disorders, diabetes, and other complications linked to depression in pregnancy, underscoring the need to diagnose and treat depression in pregnant people.

Director's Corner: Advancing Endometriosis Research
Endometriosis affects an estimated 10% of women, can cause severe pain and infertility, and typically has long delays in diagnosis. NICHD is accelerating efforts to definitively diagnose, prevent, and treat this chronic disease.
Spotlight: Scientific Advances from the Division of Intramural Research
The Division of Intramural Research provides fundamental knowledge about the nature and behavior of living systems through basic, clinical, and population-based research.
Science Update: Antibody treatment for cytomegalovirus appears to offer no benefit, suggests NIH-funded study
Two-year-old children showed no benefits from their mothers receiving antibodies that target cytomegalovirus (CMV) during pregnancy compared to those whose mothers received a placebo. Findings from this follow-up study were similar to the original, which also found no differences. Full effects of CMV infection during pregnancy may not appear until a child is two years old.
Science Update: Questionnaire may detect childbirth-related posttraumatic stress disorder, NIH-funded study suggests
An early study suggests that a questionnaire can detect posttraumatic stress disorder (PTSD) after childbirth with high probability. If large-scale studies verify its effectiveness, the questionnaire could provide a rapid and efficient method for postnatal PTSD screening, allowing timely referral for a thorough assessment and treatment.
Item of Interest: NICHD and CDC Partner on Healthy Native Babies Project
This collaboration will promote safe infant sleep with and within American Indian and Alaska Native communities.
Science Update: NIH-funded study finds no link between preconception COVID-19 vaccination and miscarriage risk
Among more than 1,800 women planning a pregnancy, those who received at least one dose of a COVID-19 vaccine before getting pregnant were no more likely to miscarry than those who were unvaccinated. The study also found no increased miscarriage risk among roughly 1,500 couples in which the male partner was vaccinated before trying to conceive.
Media Advisory: Umbilical cord milking appears to be safe in preterm infants born after 28 weeks
A treatment that moves blood from the umbilical cord into an infant’s body may provide a safe option for preterm infants born after 28 weeks who need rapid support, according to a study supported by NIH. Umbilical cord “milking”— gently squeezing the cord between the thumb and forefinger and pushing the blood into the newborn’s body—did not increase the risk of bleeding inside the brain for preterm infants born after 28 weeks of pregnancy.
Science Update: Maternal microbiome promotes placental development in mice, NIH-funded study suggests
Bacteria in the maternal digestive tract appear to stimulate blood vessel development of the placenta, suggests a mouse study. Studying the relationship between the mother’s microbiome and placental development may yield important insights into fetal and maternal health.
Director's Corner: Addressing the Tragedy of Stillbirth
Each year, more than 20,000 families in the United States experience a stillbirth, the loss of a fetus at 20 weeks or more of gestation. Stillbirth is a traumatic event that takes a devastating, lifelong psychological toll on families. October marks Pregnancy and Infant Loss Awareness Month, making this an opportune time to reflect on the work we must do to better understand the causes of—and ultimately prevent—these tragedies.
Science Update: NIH-funded study finds several potential risk factors for high blood pressure disorders of pregnancy in people with HIV
The risk for hypertensive disorders of pregnancy was higher for pregnant people with HIV if they had low CD4+ immune cell counts in the first or second trimester, or if they began taking antiretroviral drug regimens after 20 weeks of pregnancy, rather than at conception. The findings underscore the importance of getting HIV under control before becoming pregnant.
Science Update: MRI technique may predict impaired fetal growth and small size at birth, NIH-funded study suggests
A new imaging technique that measures the ability of the placenta to supply blood to the fetus may predict the chances of impaired fetal growth as early as the 14th week of pregnancy. The new method seems to allow earlier diagnosis than the standard ultrasound technique, which can detect reductions in placental blood flow at 20 to 24 weeks. Earlier detection of fetal growth restriction and risk of small for gestational age fetuses may lead to strategies for treating these conditions.
Director's Corner: Addressing the Health Effects of Climate Change
The effects of climate change on health are wide-ranging, from causing injuries and other medical concerns to disrupting vital supply chains. NICHD is committed to supporting scientific research to reduce climate-related health threats among its populations of interest—children, people of reproductive age, and people with intellectual and physical disabilities.
Item of Interest: NICHD renews funding for its Global Network for Women’s and Children’s Health Research
NICHD announced a new cycle of funding for research collaborations in its Global Network for Women’s and Children’s Health Research. The network, which is re-competed every seven years, includes U.S.-based research centers and counterparts in low- and lower middle-income countries. The Global Network has been improving maternal and child health outcomes worldwide and building health research capacity in resource-poor settings since 2001.
Science Update: Slight menstrual cycle length increase seen with SARS-CoV-2 infection, NIH-funded study suggests
Individuals with COVID-19 may experience a slight increase in menstrual cycle length, comparable to the menstrual cycle increase seen among those who received a COVID-19 vaccine, according to a study funded by the National Institutes of Health. The study authors stressed that the increase was small and temporary.
Release: NIH establishes Maternal Health Research Centers of Excellence
NIH has awarded $24 million in first-year funding to establish Maternal Health Research Centers of Excellence. The centers will develop and evaluate innovative approaches to reduce pregnancy-related complications and deaths and promote maternal health equity.
Science Update: NIH-funded researchers discover several differences in endometriosis-related gene expression
The gynecologic condition endometriosis has several differences in gene expression in the uterine lining, according to a comprehensive analysis of nearly 1,000 tissue samples by researchers funded in part by the National Institutes of Health. The differences stem from variations in DNA methylation—the binding of compounds known as methyl groups to DNA.
Science Update: Sleep-disordered breathing during mid-pregnancy may be linked to poor infant outcomes, NIH-funded study suggests
Infants born to mothers with sleep-disordered breathing—snoring, apnea, and other breathing difficulties during sleep—are more likely to develop complications such as jaundice, low blood sugar, seizures, or death during the newborn period, suggests a study funded by the National Institutes of Health. The authors called for studies to determine if treating mid-pregnancy, sleep-disordered breathing would improve infant outcomes.
Science Update: Green tea compound may inhibit processes promoting uterine fibroid growth, NIH-funded study suggests
Epigallocatechin gallate (EGCG), a compound found in green tea, appears to inhibit the biochemical processes that promote the growth and development of fibroid tumors cells, suggests a study funded in part by the National Institutes of Health. In laboratory tests of human fibroid cells, EGCG reduced the amount of a compound that promotes cell division and the quantity of proteins responsible for the tumors’ fibrous contents.
Director's Corner: Advancing Our Knowledge of Human Milk and Lactation
Strengthening our understanding of human milk biology and lactation is essential to support breastfeeding and to ensure the health of infants who do not have access to a lactating parent’s milk. NICHD supports a range of efforts to explore human milk as an active biological system and to promote the inclusion of pregnant and lactating people in clinical research.
