Innate immunity genes may influence earlier breast cancer onset in BRCA1 carriers

Damaging variants in genes involved in a rapid immune response (innate immunity) are significantly linked to earlier breast cancer onset in carriers of the harmful BRCA1 genetic mutation, reveal preliminary findings published online in the Journal of Medical Genetics.

Why vaginal microbiota transplants aren’t working yet

Vaginal microbiota transplantation without antibiotics fails to restore microbiome balance, yet engraftment suggests avenues for enhancing treatment efficacy.

Liquid biopsy enables rapid diagnosis of Burkitt lymphoma in Africa

In a study published today in Nature Medicine, researchers from the University of Oxford and the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar es salaam, Tanzania have shown that a minimally invasive "liquid biopsy" test can diagnose Burkitt lymphoma rapidly and accurately in sub-Saharan Africa, where delays in traditional testing often prove fatal.

Menopause may raise women’s Alzheimer risk earlier than doctors once thought

This review argues that women’s higher Alzheimer disease risk may be shaped in part by midlife neuroendocrine aging, especially the menopause transition, rather than by longevity alone. It highlights early menopause, bilateral oophorectomy, vasomotor symptoms, and midlife cognitive changes as underinvestigated but potentially important risk markers, while calling for sex-specific, biomarker-driven prevention strategies.

Study identifies immune cells and RANK protein as fertility regulators

The kick off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a hormone that activates the hypophysis, at the base of the skull, which then releases other hormones to start gonad –ovaries or testicles –maturation.

Repurposed kidney drug finerenone shows promise in treating premature ovarian insufficiency

Premature ovarian insufficiency (POI) is a clinically significant cause of infertility that affects between 1 to 3% of women of childbearing age.

Minimally invasive ablation effective for early-stage kidney cancers

A large national study in Denmark following nearly 1,900 patients over almost a decade found that a minimally invasive procedure called ablation is as effective as surgery for treating small kidney cancers, with faster recovery and fewer complications. Results of the study were published today in Radiology, a journal of the Radiological Society of North America (RSNA).

Study links gut microbiome health directly to ovarian aging processes

A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all bacteria and other microbes present) of the gut and ovarian health and function.

Single prenatal exposure to fungicide linked to disease across 20 generations

A single exposure to a toxic fungicide during pregnancy can increase the risk of disease for 20 subsequent generations - with inherited health problems worsening many generations after exposure.

Hormone replacement therapy shows no rise in overall mortality

Menopausal hormone therapy (commonly known as hormone replacement therapy or HRT) is not associated with an increased risk of death, finds a Danish study of over 800,000 women published by The BMJ today.

Natural ovulation offers a safer path to IVF success

Researchers compare the effects of natural ovulation and external hormone replacement regimens for preparing the uterus before frozen embryo transfer.

New prevention strategy can reduce deadly ovarian cancer risk by nearly 80%

A prevention strategy developed by Canadian researchers can reduce the risk of the most common and deadly form of ovarian cancer by nearly 80 per cent, according to a new study published today in JAMA Network Open by researchers at the University of British Columbia (UBC).

Fish study reveals how ovulation triggers sexual receptivity in females

A research team led by Hiroshima University and Tokyo University of Agriculture and Technology have proposed a neuroendocrine mechanism in bony fish that signals ovulation from the ovaries to the brain, using the medaka fish as a model; the first step to elucidate the neural circuits for facilitation of sexual receptivity in female teleosts.

Estrogen drives gut pain and explains higher rates of IBS in women

Women are dramatically more likely than men to suffer from irritable bowel syndrome (IBS), a chronic condition causing abdominal pain, bloating, and digestive discomfort.

How Traditional Chinese Medicine may reshape the gut microbiome to ease insulin resistance in PCOS

This review synthesizes evidence that gut microbiota dysbiosis contributes to insulin resistance and symptom severity in polycystic ovary syndrome through impaired barrier function, inflammation, and altered microbial metabolites. It evaluates how Traditional Chinese Medicine may modulate these pathways while highlighting major gaps in clinical validation, safety, and standardization.

Menopausal hormone therapy shows no added breast cancer risk for BRCA carriers

Using menopausal hormone therapy (MHT) was not associated with an increased risk of breast cancer in women with inherited mutations in the BRCA1 or BRCA2 genes, according to the results of a matched prospective analysis presented at the San Antonio Breast Cancer Symposium (SABCS), held December 9-12, 2025.
