Therapeutic strategies for pregnant women with lupus
The disease, which has no cure, operates much like an allergic reaction gone awry: When activated, the immune system also attacks the body's healthy cells, tissues, and organs, causing inflammation and producing a host of symptoms that, though unique to each person, are universally called flares. A highly gender-biased disease, lupus afflicts females some nine times more than … [Read more...]

Sperm may offer the uterus a ‘secret handshake’
Why does it take 200 million sperm to fertilize a single egg? One reason is that sperm, when they arrive in the uterus, face a bombardment by the immune system. Perhaps, says molecular anthropologist Pascal Gagneux, many are needed so that some will survive. On the other hand, there may be a benefit to culling so many sperm. "I'm a lonely zoologist in a medical … [Read more...]

Single women freeze their eggs to avoid ‘panic parenting,’ study finds
Most single women who freeze their eggs for non-medical reasons are doing so to avoid 'panic parenting' (entering into unwise relationships to have a genetically-related child), a new study published in Human Fertility finds. The research also indicates that clinics need to be clearer about the likelihood of having a baby with these eggs in the future. Dr Kylie … [Read more...]
Stress during pregnancy increases risk of mood disorders for female offspring
High maternal levels of the stress hormone cortisol during pregnancy increase anxious and depressive-like behaviors in female offspring at the age of 2, reports a new study in Biological Psychiatry.

A team led by Dr Daniel Roth at The Hospital for Sick Children in Toronto, say some of the most critical questions about the effectiveness of taking vitamin D supplements during pregnancy "will probably remain unanswered in … [Read more...]
Does timing of IVF to avoid weekend procedures affects pregnancy success?
It's unclear whether there is a need to retrieve a woman's eggs on weekends, in connection with in vitro fertilization/intracytoplasmatic sperm injection (IVF/ICSI) treatment in couples wishing to conceive. In a recent Acta Obstetricia et Gynecologica Scandinavica study, scheduling of eggretrieval and single embryo transfer procedures only on weekdays did not result in … [Read more...]
Fertility research brings death of dogma, birth of hope
About 13 years ago, Northeastern professor Jonathan Tilly, a reproductive biologist, made a discovery that challenged everything scientists thought they knew about female reproduction. The long-held belief that mammals were born with a set number of eggs -- and no ability to create new ones -- was wrong. Now, Tilly and his colleagues have published a new study that "puts … [Read more...]

Women won’t be told to give birth naturally
Midwives have dropped their campaign encouraging women to give birth naturally, according to a report. The Royal College of Midwives' campaign had run since 2005, promoting birth without medical intervention, such as an emergency caesarean. But they will no longer be told they should have babies without this intervention. Professor Cathy Warwick, chief executive of … [Read more...]
Period Taboo Endangering Women’s Health
An enduring taboo surrounding menstrual bleeding is endangering women’s health, a new study has found. A "culture of silence" around vaginal bleeding, from puberty through to menopause, is failing the needs of women and girls and means many are unable to tell the difference between what is healthy and what is not, researchers said. The study, conducted at Columbia … [Read more...]
