Gut microbes emerge as potential players in estrogen-driven cancers

A new review maps how the endocrine-microbiome axis expands the estrobolome concept, showing that gut microbes may alter estrogen recycling, produce hormone-like metabolites, and shape inflammation and tissue environments in hormone-driven cancers. Human evidence remains mostly associative, so the authors call for causal models, longitudinal multi-omics, multi-kingdom profiling, and sex-stratified studies before microbiome-guided cancer strategies enter routine care.

Recognizing perinatal heart failure early reduces life-threatening risks

Early detection and timely treatment of heart failure in pregnant or postpartum women are crucial to prevent serious complications, such as irregular heartbeat, stroke and death, according to a new American Heart Association scientific statement, "Heart Failure Occurring in the Perinatal Period."

Immunotherapy may help women with early ovarian insufficiency to conceive babies

A pilot study from Karolinska Institutet shows that immunotherapy may enable stimulation of egg maturation in women with autoimmune POI (premature ovarian insufficiency) – a condition that usually leads to infertility.

Study compares menopause symptom burden across different age groups

There has been a lot of discussion about how the age at menopause can affect menopause symptoms. A new study compared the prevalence and severity of menopause symptoms in women experiencing menopause around the average age of 51 years and those with premature ovarian insufficiency, showing similar symptom burden in the psychological and urogenital domains.

Oral contraceptive pills may increase binge eating in some women

A new study from Michigan State University found increases in binge eating when taking hormone pills in the form of oral contraceptives - but not in all women.

Higher BMI raises risk for 19 cancers as global review expands the obesity-cancer link

A major systematic review and meta-analysis links higher BMI to increased risk of 19 cancer types, including leukemia, non-Hodgkin lymphoma, bladder cancer, and glioma, which were not previously recognized in major consensus reports. The study also reveals regional and sex-based variation in cancer risk, with genetic evidence generally supporting many observational links while highlighting the need for more diverse global cohorts.

Hormone cycles dictate how the brain absorbs neuroprotective drugs

Consider what we ask of a clinical trial. We gather people who differ in nearly every way that matters, we give them the same drug at the same dose, and then we average the result and call the average truth.

Study maps biological pathways of weed killer during pregnancy

Exposure to glyphosate, the active ingredient in many weed killers, was linked to changes in several hormones that support pregnancy and fetal development-in one of the few studies to examine how a widely used herbicide may affect the body during pregnancy. The results come from a new study led by University of Michigan School of Public Health researchers.

Fluctuating hormones during menopause reshape brain activity patterns

Research at the Robert Larner, M.D. College of Medicine at the University of Vermont reveals how menopause, once a taboo topic, affects brain function, reinforcing the idea that the menopause transition is not only a reproductive milestone, but also a critical neurological phase.

Study links menstrual cycle timing to COVID vaccine side effects

A study of 1,474 Clue app users found that women vaccinated against COVID-19 during the follicular phase had higher odds of self-reported side effects than those vaccinated during the luteal phase.

Brain-targeted estrogen reduces breast cancer treatment side effects

Most breast cancers are worsened by estrogens. To combat the recurrence of these cancers, clinicians treat patients with inhibitors for estrogen production, like letrozole. But many patients do not adhere to this treatment due to negative side effects.

Wearable devices may help detect menstrual health changes earlier

Digital health tools, including wearables, provide critical data on menstrual health, enhancing understanding of hormonal fluctuations and women's well-being.

Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.
