A new study reveals that certain bacteria in the cervix and vagina may increase or decrease the risk of premature birth. Researchers found that some species, such as bifidobacterium and lactobacillus, lower the risk, while others, like anaerobic bacteria, significantly increase it.
Researchers found that treating subclinical hypothyroidism in pregnancy can reduce pregnancy loss, especially for those with higher TSH levels. However, treated women were more likely to experience preterm delivery and gestational diabetes.
A study published in The BMJ found that hormone treatment among pregnant women with subclinical hypothyroidism is associated with a lower risk of pregnancy loss, but an increased risk of preterm delivery, gestational diabetes, and pre-eclampsia. Women treated with thyroid hormone had a lower risk of pregnancy loss compared to untreated...

According to a new report from the USPSTF, nearly a quarter of reproductive-age women have sub-optimal folate levels, highlighting the importance of daily folic acid supplements. The FDA has also announced plans to fortify corn masa flour with folic acid, targeting Hispanic women at higher risk.
The US Preventive Services Task Force (USPSTF) strongly advises all women of childbearing age to take a daily folic acid supplement containing 400-800 μg to reduce the risk of neural tube defects in their developing fetus. This recommendation is based on high certainty that the net benefit is substantial.
A new study suggests that progesterone could be a key to preventing recurrent miscarriage in women who suffer multiple pregnancy losses. Researchers found that micronized plant-derived progesterone improved endometrial function and prevented pregnancy loss.

A study found that women with a history of recovered acute kidney injury had an increased rate of preeclampsia and delivered infants earlier than those with normal kidney function. Infants born to these women were also at higher risk for small-for-gestational-age births.
The USPSTF recommends against routine serologic screening for genital herpes infection in asymptomatic individuals, citing the lack of a long asymptomatic period and the high false-positive rate of current tests. This decision is based on the low test accuracy and potential harms of early detection and intervention.
Research finds pregnancy alters brain structure, particularly in regions related to social cognition and self-focused processing. The study suggests an adaptive process of functional specialization towards motherhood, with potential benefits for detecting the child's emotional state.
A new study published in the Journal of the American Medical Association found a significant rise in past-month marijuana use among women of reproductive age between 2002 and 2014. The prevalence increased from 2.4% to 3.9%, with higher rates among younger and pregnant women.
A recent study published in the New England Journal of Medicine found that Zika-linked abnormalities in human fetuses are more common and severe than initially thought.

A team of researchers suggests that the lifelong immunity to toxoplasmosis, once thought to be absolute, may not be as robust as previously believed. Studies have shown that even expectant mothers infected with Toxoplasma gondii at birth can still test positive for antibodies, challenging the long-held dogma.
Research from NC State University and UBC reveals a strong predictor for postpartum stress and anxiety. A woman's history of drug use is associated with heightened symptoms after childbirth, making it a valuable tool for healthcare providers to identify women at risk.
New research from Simon Fraser University aims to revolutionize In vitro fertilization (IVF) success rates using machine vision software. The software analyzes images of embryos with confirmed pregnancy outcomes to identify key developmental attributes, increasing the likelihood of successful clinical pregnancies.

This research suggests that the endometrial microbiome may play a crucial role in reproductive success.
A dose-response analysis found that pregnant women who take selective serotonin reuptake inhibitors (SSRIs) in early pregnancy are at a small but significantly greater risk of having babies with major congenital anomalies or stillbirths. The study analyzed data from over 500,000 infants and recommended enhanced scans for women prescrib...
Researchers from University of Liverpool are leading a multinational consortium to reduce mother-to-child transmission of HIV in developing countries. The DolPHIN-2 project uses a new drug Dolutegravir to rapidly reduce HIV levels, potentially preventing infant transmission and saving lives.
A recent study found that pregnant women who wanted to get vaccinated were often discouraged by healthcare professionals due to misconceptions about vaccine safety. The World Health Organization and Health Canada classify pregnant women as high-risk groups for severe flu complications.
A new study by researchers at University of California San Diego School found that women choosing to become first-time mothers later in life may increase their chances of living into their 90s. Women who had their first child at age 25 or older were more likely to live to age 90.
Researchers found that women who had their last pregnancy at 35 or older scored higher on verbal memory and executive function tests. The study suggests that hormonal changes during menopause can have a positive impact on cognitive function if they occur later in life.

Animals exposed before birth showed signs of hyperactivity, antisocial behavior, and decreased anxiety, similar to ADHD. The study could help explain the links between maternal al...
A study of over 60,000 births in South Australia found that women conceived in winter are more likely to develop gestational diabetes during pregnancy. This seasonal variation has implications for both child and mother health.
A new study published in Biological Psychiatry found that women experiencing depressive symptoms during and after pregnancy are associated with reduced cortical thickness in preschool-age children. This suggests that a mother's mood may impact her child's brain development at critical stages.
Researchers found a significant association between elevated blood sugar in early pregnancy and the risk of delivering a baby with congenital heart disease. The study, which analyzed data from 19,107 pregnant women, suggests that blood sugar levels may be a better predictor of this risk than current oral glucose tolerance tests.
A mouse study reveals that prenatal stress can alter the microbiome, leading to anxiety and learning difficulties in offspring. Researchers found lasting changes in the gut bacteria of stressed mothers and their female offspring, which persisted into adulthood.
Researchers found that women with CHD who are deemed high risk by conventional measures are more likely to have safe, healthy pregnancies than current risk-assessments suggest. The study used CARPREG and ZAHARA risk scores and found significant discrepancies between estimated and observed risks.
A study published in Diabetologia found that high iron biomarkers are linked to an increased risk of gestational diabetes in pregnant women. Higher iron stores may play a role in developing insulin resistance and oxidative stress, contributing to impaired insulin synthesis and secretion.
