More than one in three twin births and three of four births of triplets or more in the United States arise from fertility treatments, according to new estimates published in the New England Journal of Medicine. Although in-vitro fertilization (IVF) practices have improved to produce fewer triplets or higher-order births than at peak, multiples from non-IVF treatments continue unabated.

In a groundbreaking study, Yale School of Medicine researchers and colleagues at the University of Oxford have identified the chromosomal make-up of a human egg. This discovery may soon allow them to avoid using abnormal — or aneuploid — eggs during infertility treatments, and instead to pick eggs that are healthy enough for a successful in vitro fertilization (IVF) cycle.

A University of Adelaide study has identified the risk of major birth defects associated with different types of assisted reproductive technology. In the most comprehensive study of its kind in the world, researchers from the University's Robinson Institute have compared the risk of major birth defects for each of the reproductive therapies commonly available internationally, such as: IVF (in vitro fertilisation), ICSI (intracytoplasmic sperm injection) and ovulation induction. They also compared the risk of birth defects after fresh and frozen embryo transfer.

Controversy exists over how many embryos should be implanted during assisted conception (in-vitro fertilisation/IVF) therapy. New research by the University of Bristol and published in the The Lancet shows that, while discretion can be applied in whether to implant one or two embryos, three or more should never be implanted into women of any age.

Elsevier, a world-leading provider of scientific, technical and medical information products and services today announced the publication of an article in the December issue of Reproductive BioMedicine Online about miscarriage rates following IVF treatment with frozen thawed embryos which may revolutionize clinical and laboratory practice.

Researchers at Brown University and Women & Infants Hospital of Rhode Island have developed a way to extract information about gene expression from fertile human egg cells without hurting them. Expendable ‘polar bodies’ in the cells reflect much the same information as the eggs themselves, researchers have determined.
