Scientists discover new way to measure success rate of IVF embryos

Scientists at University College Dublin have discovered a new way of measuring the potential success rate of an embryo before it is transferred back into the womb during in vitro fertilisation (IVF).

Scientists discover that sperm do not function like olfactory cells

According to a 2003 study by German and American scientists, a component of the Lily of the Valley scent known as Bourgeonal alters the calcium balance of human sperm and attracts the sperm. The "Lily of the Valley phenomenon" - also the title of a book about smelling - was born as a result of this discovery that sperm act as swimming olfactory cells which follow a "scent trail" laid by the egg. However, a detailed explanation for the Lily of the Valley phenomenon remained illusive as neither Bourgeonal nor other scents could be identified in the female sex organ.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Foreign Policy examines India's growing industry of fertility treatment

Foreign Policy examines "India's flourishing fertility treatment business," a multi-billion dollar industry that "has earned India the dubious reputation of being the world's baby factory."

Transgender man falls pregnant and becomes a natural mother

A transgender man in his 30’s was able to carry a child after taking female hormones to reverse the effects of his female-to-male sex change treatment. The man from the West Midlands, UK is in a long-term relationship. It is not clear whether his partner is male or female. Medical ethics experts have called for a full inquiry into the issues surrounding transgender births, saying the interests of the child should not be risked to “fulfill the rights of an adult”.

Viewpoints: Komen takes a lashing; Is the safety net really intact?; Romney assails HHS' rule on contraception

With its roster of corporate sponsors and the pink ribbons that lend a halo to almost any kind of product you can think of, the Susan G. Komen for the Cure foundation has a longstanding reputation as a staunch protector of women's health. That reputation suffered a grievous, perhaps mortal, wound this week from the news that Komen, the world's largest breast cancer organization, decided to betray that mission.

Longer looks: Enhanced scrutiny of IVF clinics; School-based health care

Republican presidential contender Newt Gingrich hit upon a reproductive minefield on Sunday when he called for deeper scrutiny of in vitro fertilization (IVF) clinics, where women go for high-tech help to conceive.

Abortion foes take aggressive position in 2012 debate

As part of their election-year strategy, some anti-abortion groups plan to force President Obama and congressional Democrats into a corner on an abortion-related issue.

Three-parent children may be born in near future in an effort to combat mitochondrial diseases

In the next couple of years the scientific community may witness creation of children with genetic material from three parents. British scientists want to start testing a new IVF technique to try to eradicate incurable genetic diseases such as muscular dystrophy. The concept took a leap forward yesterday after the Government announced a public consultation on whether the law should be changed to allow the technique.

Implanting more embryos for IVF may do more harm than good: Study

Researchers have suggested that implanting multiple embryos for In Vitro Fertilization (IVF) may do more harm than good. This finding appeared in the current online version of the journal Lancet. The study argues against common practice of implanting multiple embryos in order to maximize a woman’s chances of conception during in vitro fertilization.

DHA plays an essential role in creating healthy sperm

Who knew that male fertility depends on sperm-cell architecture? A University of Illinois study reports that a certain omega-3 fatty acid is necessary to construct the arch that turns a round, immature sperm cell into a pointy-headed super swimmer with an extra long tail.

Twin births on the rise in the U.S.

Over the last three decades there has been a rise in the number of twins born in the U.S. Mostly this is the result of test-tube babies and women waiting to have children until their 30s, when the chances of twins increase. In 2009, 1 in every 30 babies born in the U.S. was a twin, an astounding increase over the 1 in 53 rate in 1980, according to a government report issued Wednesday.

Cardiff University technique could help predict IVF embryos with best success chances

A new technique successfully used in mice to identify embryos likely to result in a successful pregnancy could be used in humans, potentially boosting IVF success rates and helping to reduce the number of multiple births, according to Cardiff University scientists.

Serotonin, wnt are in charge of asymmetrical right-left development in embryos

Spleen to the left, appendix to the right: In order for the body to sort itself out properly, two substances have to trigger a complex chain reaction, according to the latest findings at the University of Hohenheim.

Vaginal progesterone reduces rate of preterm birth and neonatal complications

A team of investigators of the National Institutes of Health housed at the Detroit Medical Center (DMC) and Wayne State University (WSU) published today that performing a cervical ultrasound in all pregnant women and treating those with a short cervix with vaginal progesterone reduces the rate of preterm birth and neonatal complications.

New substance can replace nucleoside thymidine in DNA biosynthesis

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies.

Researchers sequence entire transcriptome of mouse neural retina

The population of Eric Morrow's seminar "Neurogenetics and Disease" comprises mainly undergraduates who were skipping down the halls of their elementary schools when the first drafts of human genome sequences were published. When Morrow, assistant professor of biology, recently asked the class how to find the mutation behind a disease, a hand shot up in the back of the class to signal the answer: "Sequence the patient's genome."

“Gold standard” stem cells for clinical testing

British researchers claim to have created stem cells of a “gold standard” quality that could lead to a new wave of treatments for degenerative diseases. Taken from human embryos, they could be available to researchers before the end of next year for eventual use in clinical trials, The Daily Telegraph reported Tuesday.

King's College London submits first clinical grade xeno-free hES cell lines to the UKSCB

Stem cell scientists at King's College London will announce they have submitted to the UK Stem Cell Bank (UKSCB) their first clinical grade human embryonic stem (hES) cell lines that are free from animal-derived products, known as 'xeno-free' stem cells.

Established human embryonic cell lines vary from newly derived stem cell lines

Established human embryonic cell lines, including those approved for federal research funding under former President George W. Bush, are different than newly derived human embryonic stem cell lines, according to a study by UCLA stem cell researchers.
