Longer studies are needed to confirm these associations and understand the long-term effects of in utero COVID-19 exposure.
A new multicenter study found that pregnant women with COVID-19 in Sub-Saharan Africa have a significantly increased risk of needing intensive care and dying compared to uninfected hospitalized pregnant women. The study also highlighted the importance of COVID-19 vaccination as part of prenatal care to improve mother and infant outcomes.

The study found a lower incidence of confirmed SARS-CoV-2 infection in infants born to vaccinated mothers compared to unvaccinated mothers.
A new study found that pregnant women's use of alcohol correlates with that of their partner, highlighting the importance of both parents reducing their alcohol consumption. The research, which analyzed data from 14,822 Finnish women and their partners, showed that exposure to alcohol can have detrimental effects on fetal development.
Researchers discovered that pregnant women produce super antibodies to protect their newborns by altering the structure of sugars attached to the antibodies. This molecular change allows immunoglobulin G to stimulate immunity through receptors that respond specifically to deacetylated sugars, providing expanded protective role.
Babies born to mothers infected with COVID-19 show differences in motor function and relaxation, especially when held. Preliminary analysis suggests increased risk of neurodevelopmental changes compared to uninfected babies.
The UK Maternal Mortality Reports show that heart disease remains the leading cause of death among women during pregnancy, followed by epilepsy and stroke. Anaesthetists are working to improve outcomes through better risk assessment, anti-clotting medication, and multidisciplinary training.

Male mice exhibit increased stress hormones and decreased pain sensitivity when near pregnant or lactating females, which is linked to a specific olfactory signal. This finding has significant implications for improving experiment reliability and represents a breakthrough in mammalian social signaling.
New experiments in mice contradict fears that COVID-19 vaccination affects fetal growth and fertility. Vaccination is shown to protect the fetus from infection, while infection reduces fetal growth. The study adds further evidence against popular claims of vaccine harms during pregnancy.
A review of 38 randomized controlled trials found that counseling patients about contraceptive use and providing contraceptives increases use without increasing STI risk or reducing condom use. The interventions also decrease unintended pregnancy in trials designed to evaluate this outcome.
A study published in Human Reproduction found that men with obesity who lost weight saw a 50% increase in sperm concentration and a 40% increase in sperm count over an 8-week period. This improvement was sustained for up to 52 weeks and even doubled for those who maintained weight loss after a year

The researchers discovered that the scream sound reduced estrogen and Anti-Mullerian hormone levels, as well as the number and quality of eggs, resulting in smaller litters.
Rates of postpartum depression symptoms increased nationwide during the pandemic, reaching a high of 7.7% in December 2020 to March 2021. States with fewer COVID-19 deaths and lower unemployment rates showed greater increases in symptoms, likely due to reduced access to support systems.
Women with hypertensive disorders of pregnancy are at a 63% higher risk of cardiovascular disease compared to those with normal blood pressure. The majority of the increased risk is accounted for by chronic hypertension, hypercholesterolemia, and type 2 diabetes.
A study funded by NIH found that women who had high blood pressure during pregnancy had a 63% increased risk for developing cardiovascular disease later in life. Early screening and monitoring in targeted areas can help delay or prevent future cardiovascular events among these women.
A study suggests that women who have had weight loss surgery should wait at least two years before trying for a baby due to the risk of having an underweight (small for gestational age) baby. The longer interval from surgery to conception is associated with a lower risk of SGA babies.
A new study by Children's Hospital of Philadelphia found that neighborhood poverty and crowding are associated with higher rates of COVID-19 in pregnancy. Researchers analyzed data from over 5,991 pregnant patients and found disparities in SARS-CoV-2 positivity among different racial and ethnic groups.

A cohort study of nearly 1,000 pregnant persons in NYC found that neighborhoods most affected by racism and economic inequality had higher rates of COVID-19 infection and preterm births. The researchers linked structural racism and community unemployment to increased risk of preterm birth.
Research by Kerim Can Kavakli and Valentina Rotondi finds that restricting US foreign aid for NGOs providing abortion information leads to higher maternal and child mortality, as well as increased HIV incidence. The study estimates that this restriction may be responsible for up to 27,000 deaths per year.
A study by Children's National Hospital found that elevated anxiety, depression, and stress in pregnant women can alter key features of the fetal brain, decreasing their offspring's cognitive development at 18 months. This alteration also increased internalizing and dysregulation behaviors.
A Canadian research team found that pregnant women and their unborn babies are sensitive to environmental contaminants like endocrine disruptors. The study highlighted the role of the placenta in regulating maternal physiology and fetal development, and linked early exposure to certain EDs with breast cancer and prostate cancer risk.
A new study published in the New England Journal of Medicine found that treating even mild forms of high blood pressure during pregnancy is safe and beneficial for both mother and developing baby. The study's results demonstrated a significant decrease in pregnancy complications, including severe preeclampsia and preterm births.
