Correction: New method for egg freezing may improve IVF success rates

Appeared in BioNews 478

In BioNews 471 we published a story which used the term 'freezing' to describe a new embryo preservation technique known as 'vitrification'. It has been brought to our attention that 'freezing' is not an accurate description of the vitrification process, which in fact uses certain chemicals and processes to avoid the formation of potentially damaging ice crystals, and is therefore more accurately described as a way of avoiding freezing.

Furthermore, the story failed to acknowledge that, although promising, the superiority of vitrification over conventional methods of egg preservation has yet to be proven and further studies will be needed to assess its clinical utility before introducing it into routine care.

It was also pointed out to us that this was not in fact the first use of the vitrification procedure in the UK. In the light of these comments, rather than correct the version of the story online, we have decided to remove it entirely. We apologise for any misunderstanding this error may have caused.

Droplet size, temperature and composition can affect the vitrification process, according to research published in PNAS last month. The findings could be used to improve the vitrification techniques used to store biological materials, including eggs for IVF treatment...

Three new independent studies have provided further evidence that embryos stored using slow-freezing techniques may be better than fresh for IVF. The studies were presented at the American Society for Reproductive Medicine conference in San Francisco, US, last week. The studies indicate that using frozen embryos rather...

The recent correspondence on egg vitrification in BioNews (1,2), prompts me to wonder if the pioneering research spirit that started the IVF industry sometimes gets a little carried away in the reality of patient care. At the start of the IVF industry the players were researchers and academics, and new...
