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: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
