Choosing healthy embryos in IVF

07.05.2002


A revolutionary method for detecting which human embryos are most likely to develop successfully to the stage at which they implant in the womb has been developed by scientists at the University of York and clinicians at Leeds General Infirmary.


The research has been funded by the Medical Research Council.

The discovery, if confirmed in clinical trials, could bring new hope for many couples undergoing fertility treatment since current failure rates are high. One of the problems is that embryos for replacement in the womb are currently judged by eye under the microscope but this method has not proved particularly successful in predicting their potential to give rise to a pregnancy.

The new method has been developed by Professor Henry Leese and colleagues in the Department of Biology at the University of York, together with members of the IVF Unit (In Vitro Fertilisation) at Leeds General Infirmary. Two days after fertilisation, embryos are placed in a culture medium containing amino acids and monitored in the laboratory to see how they consume or produce these amino acids.



Professor Leese said: “We’ve found a marked difference between the embryos which develop successfully in culture and those which do not. The healthy embryos have a ‘quieter’ metabolism.

‘The method is completely non-invasive and does not harm the embryos in any way. It opens up the prospect of selecting high-quality embryos to replace into the womb, increasing success rates, reducing the financial and emotional cost to patients and greatly eliminating the risk of multiple births. If all goes well with the clinical trials, we hope to have a diagnostic test for use in clinics in two or three years’ time.”

Professor Leese is a member of the Human Fertilisation and Embryology Authority (HFEA) which regulates, licenses and collects data on fertility treatments such as IVF and donor insemination, as well as human embryo research, in the UK.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
