John Watersone , Dr. Recommended reading. There are many reasons for this, of course, and there has been progress with, for example, increasing NHS funding in the UK.

But given that pregnancy rates following IVF have almost doubled over the period, with rates in women under 35 reaching almost 50 per cent, and that diagnostic accuracy has been transformed, I really believe it is time that PGD is accepted into mainstream clinical genetics and proactively promoted as an effective strategy, particularly for younger couples. Furthermore, with microarray-based tests now available to screen for hundreds of mutations causing a range of relatively common single gene defects, there is a real prospect of making an impact on the incidence of these diseases which could deliver substantial savings for health systems around the world compared with the cost of treating and caring for affected individuals in some cases over decades at a time of global recession.

So there are plenty of challenges for the next generation to tackle in the next 20 years! By posting a comment you agree to abide by the BioNews terms and conditions.

Report backs role of PGS in assisted reproduction. By Linda Geddes. Baby Connor has made history. Connor, a healthy baby boy, has made history. He is the first child to be born after his parents had the entire genomes of a batch of their IVF embryos screened for abnormalities, with the intention of picking the healthiest for implantation.

The technique could increase the number of successful pregnancies from IVF. IVF accounts for between 1 and 5 per cent of all births in developed countries, but it is very inefficient. The problem is that many abnormal embryos look normal under a microscope. To do this, he first took cells from seven 5-day-old embryos and extracted their DNA. He then used a technique called next-generation sequencing NGS to assess the number of chromosomes in each cell.

This involves breaking the DNA into fragments that a computer then reads and predicts where on the chromosome each fragment came from.

They were merely interested in the proportion of DNA coming from each chromosome. In earlier studies, the team had compared the DNA fragments produced using NGS from healthy cells, those taken from abnormal embryos and those taken from cells with known chromosomal abnormalities. These were used as a library against which the DNA from the seven embryos could be compared.

A second woman is also expecting a baby after undergoing the same process. Neither woman has a history of inherited disease, they merely wanted to maximise their chances of having a baby through IVF.
