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

The natural estrogens produced by women are steroid molecules, which means that they are derived from a particular type of molecular skeleton containing four rings of carbon atoms, giving the shape shown here. The most prevalent forms of human estrogen are estradiol and estrone. Both are produced and secreted by the ovaries, although estrone is also made in the adrenal glands and other organs.
Incidence and severity emerging CVD risk factors may differ between genders

Incidence and severity emerging CVD risk factors may differ between genders

The incidence and severity of both traditional and emerging cardiovascular disease (CVD) risk factors as well as the response to treatment may differ between genders. In this narrative review, several emerging CVD risk factors (i.e. inflammatory and haemostatic markers, endothelial dysfunction, homocysteine, lipid disorders, microalbuminuria/proteinuria, coronary artery calcium score, arterial stiffness, periodontitis, inflammatory bowel syndrome, obstructive sleep apnea, impaired glucose metabolism, metabolic syndrome and non-alcoholic fatty liver disease) are discussed in the context of gender differences.

Women who eat more high-fiber foods during young adulthood may have lower breast cancer risk

Women who eat more high-fiber foods during young adulthood may have lower breast cancer risk

Women who eat more high-fiber foods during adolescence and young adulthood--especially lots of fruits and vegetables--may have significantly lower breast cancer risk than those who eat less dietary fiber when young, according to a new large-scale study led by researchers at Harvard T.H. Chan School of Public Health. [More]
Early puberty may increase risk of developing gestational diabetes

Early puberty may increase risk of developing gestational diabetes

Women who began having menstrual cycles at a younger age are at greater risk of developing gestational diabetes, a disease affecting up to 7 percent of pregnant women that can cause babies to develop type 2 diabetes and other complications, new research shows. [More]
Nutrition and breast cancer; starving triple negative breast cancer cells to death: an interview with Associate Professor Jeff Holst

Nutrition and breast cancer; starving triple negative breast cancer cells to death: an interview with Associate Professor Jeff Holst

While there are a range of reports that different foods and food groups can increase or decrease your risk of cancer, these associations are very difficult to scientifically verify. [More]
Oestrogen supplements could reduce dementia risk in women

Oestrogen supplements could reduce dementia risk in women

Women who take oestrogen supplements from before or at the start of menopause and continue with them for a few years have better preserved brain structure, which may reduce the risk of dementia. [More]
Migraines heat up as women near menopause

Migraines heat up as women near menopause

Migraine headaches heat up as women approach menopause, according to a new study from researchers at the University of Cincinnati, Montefiore Headache Center, Albert Einstein College of Medicine and Vedanta Research. [More]
Study findings may help explain why risk of stroke changes after menopause

Study findings may help explain why risk of stroke changes after menopause

Risk of stroke in women may come down to a compound the body produces from estrogen known as 2-methoxyestradiol (2-ME). Furthermore, the compound's therapeutic potential may extend beyond treating stroke in women to healing brain injuries in men, a new study in American Journal of Physiology—Endocrinology and Metabolism reports.

Estrogen helps women fight flu virus better than men

Estrogen helps women fight flu virus better than men

Estrogen dramatically reduced the amount of flu virus that replicated in infected cells from women but not from men, a new study by researchers at the Johns Hopkins Bloomberg School of Public Health shows. [More]
Estrogen may protect women against flu

Estrogen may protect women against flu

The female sex hormone estrogen has anti-viral effects against the influenza A virus, commonly known as the flu, a new study in American Journal of Physiology—Lung Cellular and Molecular Physiology reports. [More]
Having more kids may lead to slower rate of aging

Having more kids may lead to slower rate of aging

A study by Simon Fraser University researchers suggests that the number of children born to a woman influences the rate at which her body ages. [More]
Biocept introduces blood-based test for detection, monitoring of prostate cancer and breast cancer

Biocept introduces blood-based test for detection, monitoring of prostate cancer and breast cancer

Biocept, Inc., a molecular diagnostics company commercializing and developing biomarkers to improve the detection and treatment of cancer, announces the launch of the CLIA-validated androgen receptor expression assay using a patient's blood for the detection and monitoring of late-stage prostate cancer and a certain form of breast cancer.

Older age at menopause associated with lower depression risk

Older age at menopause associated with lower depression risk

A review of medical literature suggests older age at menopause was associated with a lower risk of depression for women in later life. Eleni Th Petridou, M.D., M.P.H., Ph.D., of the National and Kapodistrian University of Athens, Greece, and coauthors included 14 studies in a meta-analysis that represented nearly 68,000 women.

New phase III trial takes intravaginal DHEA a step closer to approval

New phase III trial takes intravaginal DHEA a step closer to approval

A new phase III trial with positive results is taking intravaginal DHEA a step closer to governmental approval. The formulation could provide women who cannot or do not wish to use intravaginal estrogen with an effective vaginal alternative for easing vaginal symptoms and pain with sex after menopause. [More]
Fraunhofer scientists use antibodies to detect cancer cells in tissue samples

Fraunhofer scientists use antibodies to detect cancer cells in tissue samples

Antibodies combat viruses and bacteria. They also attach themselves to cancer cells - in a typical, characteristic way. Fraunhofer scientists are using this property to detect cancer cells in tissue samples. Such rapid tests can already be applied by surgeons during operations - within a few minutes and without expensive equipment. [More]
Women suffering from blood clots can safely take hormone replacement therapy with anticoagulants

Women suffering from blood clots can safely take hormone replacement therapy with anticoagulants

New research published online today in Blood, the Journal of the American Society of Hematology (ASH), is the first to demonstrate that women on blood thinners can take estrogen-containing contraception or hormone replacement therapy without an increased risk of blood clots or uterine bleeding.

TSRI-led study finds potential new therapeutic approach for hard-to-treat breast cancers

TSRI-led study finds potential new therapeutic approach for hard-to-treat breast cancers

Findings from a new study led by scientists from the Florida campus of The Scripps Research Institute (TSRI) suggest a potent new therapeutic approach for a number of hard-to-treat breast cancers. [More]
Berkeley Lab researchers develop new mouse model for most common form of breast cancer

Berkeley Lab researchers develop new mouse model for most common form of breast cancer

The first clinically-relevant mouse model of human breast cancer to successfully express functional estrogen receptor positive (ER+) adenocarcinomas has been developed by researchers at Lawrence Berkeley National Laboratory. [More]
High testosterone levels in women may increase uterine fibroid risk

High testosterone levels in women may increase uterine fibroid risk

Women who have high levels of both testosterone and estrogen in midlife may face a greater risk of developing benign tumors on the uterus called uterine fibroids than women with low levels of the hormones, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
