Study finds that a woman's chances of having twins can be modified by diet
An obstetrician well known for his care of and research into multiple-birth pregnancies has found that dietary changes can affect a woman's chances of having twins, and that her overall chance is determined by a combination of diet and heredity. view more (2006-05-22)
New brain hormone puts brakes on reproduction
University of California, Berkeley, researchers have discovered a new actor in the mammalian reproductive system, a hormone that fills a role long suspected, but until now undetected. view more (2006-02-07)
Abortion-Rights and Anti-Abortion Groups Share Some Values
People with strong views on abortion and other controversial issues tend to exaggerate differences of opinion they have with their opponents, a new University of Florida study finds. view more (2006-01-27)
Bone marrow may be source of new egg-cell generation in adult mammals
Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood. view more (2005-07-28)
Flatworm genes may provide insights into human diseases, researchers say
Could vital information about many human diseases be deciphered from genes inside freshwater flatworms? A definitive yes is not the answer yet, but research at the University of Illinois at Urbana-Champaign has provided an important advance for pursuing both that idea and the biology of stem cells. view more (2005-12-14)
Eggs from embryonic stem cells could benefit sterile women
Monash researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs. view more (2005-06-20)
Hermaphroditic plants have genetic advantage in areas where extinctions are frequent
In one of the first studies to empirically compare the reproductive success of hermaphrodites and male and female populations, biologists from the University of Oxford make use of the rare and extreme sexual diversity displayed in a species of European weed to test the hypothesis that hermaphrodites have been selected in regions with frequent... view more...

Behavioural therapy can restore ovulation in infertile women
Fertility can be restored in some women by the use of behavioural therapy, thus avoiding recourse to expensive medicines and complex procedures, a scientist told the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic on Tuesday 20 June 2006. view more (2006-06-20)
Procedure allows women to freeze eggs to preserve future fertility
Researchers at the Yale Fertility Center are now offering a cutting edge reproductive procedure called oocyte cryopreservation that allows women to freeze their eggs and use them at a later time to conceive a child. view more (2006-01-30)
Fish evolve a longer lifespan by evolving a longer reproductive period, researchers find
A UC Riverside-led research team has found that as some populations of an organism evolve a longer lifespan, they do so by increasing only that segment of the lifespan that contributes to "fitness" - the relative ability of an individual to contribute offspring to the next generation. view more (2005-12-27)
Fewer wrinkles and firmer skin linked to earlier use of estrogen therapy
Long-term hormone estrogen therapy used earlier in menopause is associated with fewer wrinkles and less skin rigidity in postmenopausal women, Yale School of Medicine researchers report in the August issue of Fertility and Sterility. view more (2005-08-29)
Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory
Scientists in the UK have proved that human embryonic stem cells can develop in the laboratory into the early forms of cells that eventually become eggs or sperm. view more (2005-06-20)
Common pesticide may reduce fertility in women
Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology. view more (2005-09-13)
Markers of PCOS inherited, persist and raise risk for heart disease, diabetes
Menstrual irregularity and unhealthy metabolic traits associated with polycystic ovary syndrome (PCOS) are inherited and persist with age, putting women with PCOS at a high risk for cardiovascular disease and type 2 diabetes. view more (2006-04-18)
First frozen egg baby born in Canada
The McGill University Health Center (MUHC) in Montreal is pleased to announce the first successful birth in Canada resulting from frozen eggs. view more (2005-05-30)
Males with elevated levels of testosterone lead shorter lives but have more success siring offspring
Comparative studies have studied testosterone levels and related them to mating systems and aggression, but very few studies have attempted to relate testosterone to fitness, that is, the combination of lifetime reproductive success and survival, in the wild or experimentally. view more (2006-04-13)
Novel diagnosis of preeclampsia with proteomic analysis
Researchers at Yale School of Medicine have found that analyzing proteins in urine is a simple and objective method to diagnose and classify preeclampsia (PE), a complication of pregnancy causing high blood pressure after 20 weeks of gestation. view more (2006-02-06)
Study hints at role of stem cell genes in testicular, breast cancers
UCSF scientists have discovered that the activity of several embryonic stem cell genes is elevated in testicular and breast cancers, providing some of the first molecular evidence of a link between embryonic stem cells and cancer. view more (2005-11-30)
Migraine treatment and prevention in women
Migraines are more common in the United States than diabetes, osteoarthritis or asthma. Of the 28 million people who experience migraines in this country, 18 million are women. view more (2006-09-07)
South Pacific plant may be missing link in evolution of flowering plants
A new University of Colorado at Boulder study involving a "living fossil plant" that has survived on Earth for 130 million years suggests its novel reproductive structure may be a "missing link" between flowering plants and their ancestors. view more (2006-05-18)
