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: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
