Study explores pregnancy risks from heat and wildfire smoke

Wildfire smoke and extreme heat – increasingly the new norm – each have their own harmful effects on pregnant people and babies, including preterm birth and low birthweight.

Male contraception has barely changed in a century. What comes next?

A review traces more than 5,000 years of male contraception, from early penile sheaths and the development of modern condoms and vasectomy to today's search for reversible alternatives. Researchers are now testing hormonal gels, non-hormonal compounds and vas-occlusive technologies, although these approaches remain at different stages of preclinical and clinical development.

A large US study found no overall link between fluoride in pregnancy and children’s behavior

A US cohort study of 5,520 children found no overall association between prenatal exposure to fluoride in public drinking water and internalizing or externalizing behavioral problems across the primary analyses. Exploratory analyses identified some associations with externalizing problems at higher fluoride concentrations and in certain subgroups, but the researchers said these findings require further investigation.

Medicaid ACOs can improve maternal care quality and equity

A new study details how Medicaid Accountable Care Organizations can improve maternal healthcare quality and equity in the US by aligning performance mandates with innovative care coordination and social needs support among patients before, during, and after pregnancy.

Women use creatine differently from men, survey reveals

A cross-sectional survey of 2,094 current or recent creatine users found that women were more concentrated in shorter-duration use groups than men and reported different supplementation goals, information sources, and knowledge patterns. Women were less likely to cite athletic performance and more likely to cite healthy aging as a goal, while researchers cautioned that the survey design cannot explain why these differences exist.

The link between fish and pregnancy hypertension may start before conception

In a nationwide Japanese cohort of more than 86,000 women, higher fish intake before pregnancy was associated with lower odds of early-onset hypertensive disorders of pregnancy, while fish intake during pregnancy showed different associations with late-onset disease, particularly among women who had not previously given birth. Total dietary omega-3 and omega-6 PUFA intake showed much less consistent associations, suggesting that the relationship with fish consumption may not be explained by total PUFA intake alone.

Early pregnancy emotions may predict childhood developmental delay risks

Pregnancy is often one of the biggest emotional and physical transitions in a woman's life. Alongside the well-known physical changes, many women also experience shifts in mood and mental health during pregnancy and after giving birth, with anxiety and depression being quite common.

Prenatal paracetamol exposure linked to smaller ovaries in daughters

Researchers in Denmark have found that girls whose mothers took paracetamol during pregnancy had smaller ovaries, fewer ovarian follicles (the structures that contain immature eggs), smaller uteruses and lower levels of reproductive hormones at three months old.

Study identifies 14 egg-layer gene variants linked to female infertility

Researchers determine 14 variants in the egg's protective layer associated with female infertility which can affect assisted reproductive technology outcomes.

The vaginal microbiome may be an overlooked reservoir of antibiotic resistance

Researchers analyzed 1,957 vaginal metagenomic samples from 1,547 pregnant women and found that bacterial community structure was strongly associated with the diversity and distribution of clinically relevant antibiotic resistance genes. Lactobacillus crispatus-dominated communities carried comparatively few acquired resistance genes, while L. iners-dominated and anaerobe-rich communities showed greater resistance diversity, with PPROM associated with broader predicted resistance profiles among ARG-positive samples.

What mothers eat in pregnancy may shape a child’s weight years later

A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

Bariatric surgery restores menstrual cycles and reduces polycystic ovaries in obese women

Metabolic bariatric surgery improves menstrual cycle frequency and symptoms of polycystic ovaries in women living with obesity, a new study from the University of Surrey reports.

GLP-1 drugs appear psychiatrically safe, but one finding still raises questions

A systematic review of 11 observational studies representing more than 4.9 million patients found that GLP-1 receptor agonists were generally associated with neutral or potentially protective psychiatric outcomes, although one obesity-focused cohort reported increased risks of depression, anxiety, and suicidal behavior. Direct evidence for antidepressant effects remains limited, with only one cross-sectional study using validated mood scales and no randomized trials in the final synthesis, meaning causality cannot be established

What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.

Pregnant Filipina women reveal creative ways to manage stress

The everchanging social, political, and economic landscape in many countries has become more tenuous and intense in recent years.

Gestational diabetes history linked to earlier development of type 2 diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that, in women that develop type 2 diabetes (T2D), those who had gestational diabetes (GD) when pregnant are developing T2D on average almost 13 years earlier than those who did not.

Alpha-1 antitrypsin identified as potential target for preventing spontaneous preterm birth

Researchers at the University of Oulu have identified alpha-1 antitrypsin as a potential target for preventing spontaneous preterm birth.

Biodegradable 'nanobone' material helps body regrow jawbone

For children born with cleft lip and palate, repairing gaps in the jawbone often means waiting until they are 10 to 12 years old before undergoing invasive bone graft surgery.

Targeting KV7 proteins could help delay preterm labor

Scientists have found that targeting a particular group of proteins in the uterus muscle (myometrium) can suppress human uterine contractions in laboratory studies and delay preterm birth in a preclinical model.

High-dose folic acid appears safe from formaldehyde toxicity

Folic acid – an essential vitamin added to flour and cereals and prescribed at high doses for cancer patients and people with blood disorders – does not elevate toxic formaldehyde in the body, according to a new Cornell University study on mice and human cancer patients who consumed high doses.
