Estrogen

Estrogens are a family of related molecules that stimulate the development and maintenance of female characteristics and sexual reproduction.

What is Estrogen?

Estrogens (also called Oestrogens) are steroid compounds that are important for development and functioning of females of the species. They are named so because they play an important role in the estrous cycle. Their name comes from estrus/oistros (period of fertility for female mammals) + gen/gonos = to generate.

Many women suffer in silence from treatable pelvic floor conditions

Many women assume pelvic floor health issues are simply their fate—part of having vaginal deliveries, getting older, gaining weight or entering menopause. Perhaps they have watched their mothers and grandmothers live with symptoms, such as urinary incontinence and pain.

Injury burden is higher during menstruation in professional female footballers

The menstrual cycle is a key physiological process in women: it impacts performance, neuromuscular control, metabolism, and immune response.

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.

Researchers unravel why mRNA-based vaccines for COVID-19 can cause heart damage

Stanford Medicine investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents - and they've shown a possible route to reducing its likelihood.

Next-generation oral SERD therapy lowers the risk of breast cancer recurrence

In an international study led by UCLA, researchers have shown that giredestrant, a next-generation oral selective estrogen receptor antagonist and degrader (SERD), when given as an adjuvant therapy for early-stage (1-3) hormone receptor (HR)-positive, HER2-negative breast cancer, significantly lowered the risk of the disease returning when compared with standard hormone therapies long considered the backbone of treatment.

Sterilized fermented beverage targets obesity and type 2 diabetes pathways in computational study

Researchers profiled a terminally sterilized probiotic-fermented MFH beverage and identified aporphine alkaloids and flavonoids with favorable predicted ADMET properties. Integrated network pharmacology, molecular docking, and 100-ns MD simulations suggest multi-target engagement of metabolic-inflammatory pathways relevant to obesity and type 2 diabetes.

Scientists uncover why SETX-deficient cancer cells rely on error-prone DNA repair

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break-when both sides of the DNA helix are cut at once.

Study uncovers strategy to sensitize estrogen receptor–positive breast tumors to immunotherapy

A study led by researchers at the Hospital del Mar Research Institute advances one of the most significant milestones in breast cancer treatment, making immunotherapy effective against the most common tumor type, estrogen receptor-positive or luminal breast cancer.

Obesity-driven estrone emerges as a key driver of deadly postmenopausal breast cancer

A new analysis of research into the most common type of breast cancer has zeroed in on an overlooked hormone that may be responsible for the increased risk of breast cancer death in post-menopausal women with obesity.

Beer bellies linked to worse heart structure changes especially in men

A large new study using advanced imaging found that abdominal obesity, sometimes referred to as a "beer belly," is associated with more harmful changes in heart structure than overall body weight alone, especially in men.

Study explores how elevated growth hormone levels contribute to liver aging

A new research paper was published in Volume 17, Issue 10 of Aging-US on October 3, 2025, titled "Growth hormone excess drives liver aging via increased glycation stress."

Innovative research reveals FGD3 as a key player in breast cancer cell death

A naturally occurring protein that tends to be expressed at higher levels in breast cancer cells boosts the effectiveness of some anticancer agents, including doxorubicin, one of the most widely used chemotherapies, and a preclinical drug known as ErSO, researchers report.

Switching APOE4 to APOE2 in adult mice reduces Alzheimer’s pathology and improves memory

Replacing APOE4 with APOE2 in adult mice rapidly reshapes brain lipids and gene expression, even after development is complete. This switch, especially when targeted to astrocytes, reduces amyloid burden, dampens gliosis, and improves associative memory despite E2-like peripheral lipid risks.
