A meta review of 11 studies comparing outcomes of some 37,000 pregnancies using IVF shows that cryopreservation seems to reduce the chances of premature birth, low birth weight and ante-partum haemorrhage. An associate risk with the use of cryopreservation seems to be an increase in caesarean section, although overall the difference in risks following fresh and cryopreserved embryo transfer was low.
Researchers from the University of Aberdeen and Aberdeen Maternity Hospital, lead by Dr Abha Maheshwari, undertook the study and published results in the journal Fertility and Sterility presenting it at the British Science Festival recently. http://www.fertstert.org/article/S0015-0282(12)00573-0/abstract
This follows another study undertaken by the British Fertility Society, who presented similar findings, reported by the BBC http://www.bbc.co.uk/news/health-16430139
Estimates say there have been perhaps half a million cryopreserved births since Zoe Leyland's in 1984. The Aberdeen research goes back many years in some cases - when nearly all embryos were cryopreserved using slow freezers. The new vitrification technique has been experimented with since the 1980s but has only been in mainstream use over the last four or five years, so much of the data being used may relate to controlled rate freezers.

The Society holds at least one main meeting each year. This year it is in Lodon, Thursday 11th of Ocotober to Friday the 12th. The programme includes both a symposium on a topical subject and a session of free communications on any aspect of low temperature biology. Recent symposia have included long-term stability, preservation of aquatic organisms, cryopreservation of embryos and gametes, preservation of plants, low temperature microscopy, vitrification, freeze drying and tissue banking.

ASRM 2012- Annual Meeting & Exhibition - takes place at the Convention Center in San Diego, USA on 20-24 August 2012, where Planer will be exhibiting the DATAcentre monitoring & alarm system, and the ShipsLog temperature /data logger for Vapour Shippers and our Kryo 360 - 1.7 controlled rate freezer. We look forward to welcoming you at booth number 514. You can find more information at the show here: http://www.asrm.org
We recently welcomed Distributors from Canada to learn more about the DATACentre range - our old friends Diamed from near Toronto and a new face - Somagen Diagnostics based in Edmonton, Alberta. Andrew Johnson attended from Diamed and representing Somagen was Marcus Crombie - pictured here. They were joined by our Dutch distributors CryoSolutions for part of the time.
The DATACentre is our stand alone monitoring and alarm system for labs An economical system, it can monitor temperature, humidity, CO2, liquid nitrogen level, O2, door status - and more. It connects to up to 120 wireless sensors. Real time and historical data can be viewed in graphical or text format and alarms can be acknowledged and managed. Optionally the system may also be connected directly to a PC or to a LAN port in the building and we then offer further data management solutions.
We don't like our guests to leave without a taste of good English food and Nick Pattenden organised a trip to Red Dog Saloon in Hoxton (www.reddogsaloon.co.uk)
