Treatment with estrogen dramatically lowers rates of stomach cancer in male mice

Several types of cancer, including stomach, liver and colon, are far more common in men than in women. Some scientists have theorized that differences in lifestyle, such as diet and smoking, may account for the discrepancy, but growing evidence suggests that the differences are rooted in basic biological differences between men and women.

Smoking, social class may lead to POF in women

POF is not only associated with infertility but also with significantly increased morbidity and mortality, as well as a decreased quality of life equivalent to that of people with type 2 diabetes or rheumatoid arthritis, said Dr. Rumana Islam, from Imperial College, London, UK.

New insight into oocyte chromosome abnormalities

Ovarian stimulation undertaken by women of advanced maternal age receiving fertility treatment may be disrupting the normal pattern of meiosis - a critical process of chromosome duplication followed by two specialised cell divisions in the production of oocytes and sperm - and leading to abnormalities of chromosome copy numbers that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as Down's syndrome, which is caused by the inheritance of three copies of chromosome 21.

Early metformin treatment may prevent adolescent polycystic ovary syndrome

A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that early, prolonged treatment with the diabetes drug metformin may prevent or delay the development of polycystic ovary syndrome (PCOS) in adolescence.

Eating at wrong time of the day reduces fertility in fruit flies

Dieticians will tell you it isn't healthy to eat late at night: it's a recipe for weight gain. In fruit flies, at least, there's another consequence: reduced fertility.

Ovarian cancer screenings do not reduce risk of death

A University of Alabama at Birmingham study released today reports that ovarian cancer screenings do not reduce a woman's risk of death from the disease and the invasive medical procedures may create associated health problems.

Anti-Mullerian hormone test can indicate reproductive function in young women with cancer

A test that shows how many eggs a woman has in her ovaries may help young women with breast cancer know what their reproductive function will be after chemotherapy, a new study finds. The results will be presented Sunday at The Endocrine Society's 93rd Annual Meeting in Boston.

Women with ovarian cancer do not benefit from CA-125 and transvaginal ultrasound

In a clinical trial that included nearly 80,000 women, those who received ovarian cancer screening did not have a reduced risk of death from ovarian cancer compared to women who received usual care, but did have an increase in invasive medical procedures and associated harms as a result of being screened, according to a study in the June 8 issue of JAMA, a theme issue on cancer.

Screening unhelpful in lowering deaths from ovarian cancer

New research shows that women regularly screened for ovarian cancer are just as likely to die from the disease. This comes as no surprise as there are still no adequate detection methods, says Ovarian Cancer Australia. Of the 1,200 Australian women diagnosed with ovarian cancer each year, 800 die, often because it is diagnosed too late to be treated.

HRT reduces risk of breast cancer in women with BRCA mutations after ovary removal

Women with the BRCA1 or BRCA2 gene mutations, which are linked to a very high risk of breast and ovarian cancer, can safely take hormone-replacement therapy (HRT) to mitigate menopausal symptoms after surgical removal of their ovaries, according to new research from the Perelman School of Medicine at the University of Pennsylvania which will be presented Monday, June 6 during the American Society for Clinical Oncology's annual meeting.

New insights into pathogenesis and treatment of hereditary breast, ovarian cancer

5% to 10% of all breast cancers are monogenic in origin. In other words, there is a mutation of the genes BRCA1, BRCA2 or other high-risk genes. In this edition of Deutsches Ärzteblatt International, Alfons Meindl of the Klinikum rechts der Isar and coauthors report on new insights into the pathogenesis and treatment of hereditary breast and ovarian cancer and newly-discovered risk genes.

Caffeine reduces muscle activity in Fallopian tubes

Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb. "Our experiments were conducted in mice, but this finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman's chance of becoming pregnant," says Professor Sean Ward from the University of Nevada School of Medicine, Reno, USA. Ward's study is published today in the British Journal of Pharmacology

Study finds strong link between live birth rates and number of eggs retrieved in one IVF cycle

An analysis of over 400,000 IVF cycles in the UK has shown that doctors should aim to retrieve around 15 eggs from a woman's ovaries in a single cycle in order to have the best chance of achieving a live birth after assisted reproduction technology.

Treatment with estrogen-lowering drugs shrinks tumors and reduces mastectomy rates in breast cancer patients

In the first large trial of its kind in the United States, researchers have shown that estrogen-lowering drugs can shrink tumors and reduce mastectomy rates for patients with stage 2 or 3 breast cancer.

Study finds more evidence linking high-grade serous ovarian cancer to fallopian tubes

High-grade serous ovarian cancer (HGSOC), the fifth-deadliest cancer among American women, is thought by many scientists to often be a fallopian tube malignancy masquerading as an ovarian one. While most of the evidence linking HGSOC to the fallopian tubes has so far been only circumstantial, a new Dana-Farber Cancer Institute study suggests there is a direct connection, a finding that could aid in the development of better treatments for the cancer.

Organic pollutants in flame retardents cause molecular changes in reproductive organs

Polybrominated diphenyl ethers (PBDEs) are chemicals that have been widely used as flame retardants and are now classified as persistent organic pollutants. Health concerns in humans have arisen based primarily on studies with laboratory animals exposed to high levels of PBDEs. Three commercial mixtures of PBDEs have been manufactured in or imported into the United States which include penta-, octa-, and deca-brominated diphenyl ethers (BDEs).

New treatment approach raises hope for women with ovarian cancer

Researchers at Oregon Health & Science University's Oregon National Primate Research Center may have good news for women at high-risk for ovarian cancer who also want to have children.

Study shows immune therapy can prevent pregnancy in mammals including humans

Researchers at Weill Cornell Medical College have shown that it is possible to immunize mammals to control fertility. They say their technique could possibly be used on other mammals -- including humans -- because fertility hormones and their receptors are species-non-specific and are similar in both females and males.

EMA CHMP adopts positive opinion for Teva's NOMAC-E2 contraceptive pill

Teva Pharmaceutical Industries Ltd. today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion for NOMAC-E2, an investigational contraceptive pill combining 1.5 mg of 17-beta-estradiol with 2.5 mg of nomegestrol acetate in a 24/4 monophasic regimen.
