A mammalian embryo in the first stage of development, when the fertilised egg has grown into a hollow ball made up of a few hundred cells.
US researchers have developed a means to predict which human embryos produced through IVF are most likely to result in healthy births. Researchers filmed 242 one-cell embryos and predicted, with more than 93 percent accuracy, those that would survive up to five days. These findings may improve the success rate of IVF....
The probability of having a male baby is affected by fertility treatments, Australian scientists have found. The national population-based study is the first to assess the impact of fertility treatments on the ratio of boys to girls born...
At the beginning of this month, following the European Society for Human Reproduction and Embryology (ESHRE) annual meeting in Rome, a workshop was held to celebrate 20 years of preimplantation genetic diagnosis (PGD)...
Women using assisted reproductive technology (ART) to conceive have a higher rate of miscarriage if they are overweight, say a group of UK scientists....
Research at Newcastle University funded by the Muscular Dystrophy Campaign has shown that it might be possible to prevent mitochondrial diseases being passed from mother to child...
A US company has been granted beneficial 'orphan drug' status by the American Food and Drug Administration (FDA) for an embryonic stem cell therapy it's developing to treat a rare form of blindness...
The US National Institutes of Health (NIH) has proposed a broader definition of 'human embryonic stem cell' (HES), which would allow Federal funding of research using cells at an early development stage....
Preimplantation genetic screening (PGS) for aneuploidy was first reported by Verlinsky et al (1995) and Munne et al (1995). Both of these initial studies analysed polar bodies. The aim of the technique is to help determine the best IVF embryo for transfer on the grounds of the polar body or embryo's chromosomes, by performing biopsy and analysis of the chromosomes using fluorescent in situ hybridisation (FISH). There have been hundreds of papers on the use of PGS. It is well known that for pa...
Elective single embryo transfer (eSET) policy implementation has raised many issues among patients, IVF experts and fund holders. The main concern in relation to this policy is that we do not know how much, and by what percentage, it will reduce the pregnancy rate in our patients. The policy says...
Nataly Atalla's uncritical advertorial 'freeze and share: an evolution of egg sharing' in BioNews 476 (week 15/9/2008 - 21/9/2008) did not address a number of important points. I would have expected some comment on the success rate of the vitrification technique in their hands. She cites 100,000...
