According to data presented by the European IVF Monitoring Group (EIM), 479,288 treatment cycles were reported in 32 European countries in 2007 . This compares globally with 142,435 cycles from the US and 56,817 cycles from Australia and New Zealand. "The number of cycles performed in many developed countries has grown by 5-10% per annum over the last 5 years," said Dr. Jacques de Mouzon, chairman of ESHRE's EIM. "The 4.5% increase we observed in Europe from 2006 to 2007 however is partly due to more clinics reporting to our database," he added.
In 28 countries where clinics reported deliveries, more than 90,000 babies were born in 2007. There were 118,667 regular IVF treatments, 246,687 intracytoplasmic sperm injection (ICSI) cycles, 74,855 frozen embryo transfer cycles (FER), 15,028 egg donor cycles (ED), 6,822 preimplantation genetic diagnosis/screening cycles (PGD/PGS) and 660 in vitro maturation cycles (IVM). "The reverse trend from IVF to ICSI continues with now 67.5% of fresh cycles using the latter technology, although the efficacy of ICSI in terms of pregnancy rates is the same as standard IVF," he added.
He pointed out that the overall rate of multiple births was very similar to the previous year with European ART twin deliveries at 20.5% and triplet deliveries at 0.8%. Most countries in Europe are now recording fewer than 1% triplet deliveries, except for Italy (2.8%), Latvia (11.1%) and Serbia (3.3%). "The good news is that since 1997, we have observed a decline from 30% to 21% in overall multiple birth rates and a fourfold reduction in triplet deliveries from 3.7% to 0.8%," he said.
Nordic countries like Denmark still have the highest availability of ART at 13,263 cycles per million of women aged 15-45. The lowest availabilities were recorded in the largest economies in Europe such as Germany (3,931), UK (3,794) and Italy (3,829). This is also mirrored in the number of infants born after ART with only 1.5% in Germany, 1.8% in the UK and 1.2% in Italy. In comparison in Denmark 4.9% of all children were born through IVF.
"In the last 11 years since the beginnings of the EIM we have seen a gradual increase of 26% to 33% of pregnancies per transfer for IVF and ICSI, from 15% to 22% for FER and from 27% to 46% for oocyte donation, and all this despite the transfer of fewer and fewer embryos," said Dr. de Mouzon.
In order to further assess the safety of ART, the EIM has initiated a major study (MART - the Morbidity in ART study), collecting data from a large series of ART children born in Scandinavia. Funded by ESHRE and the Medical Faculty of Copenhagen University, the team will analyse data from the national ART registers in Denmark, Finland, Norway and Sweden. "We estimate that we will have about 75,000 children in our database at the end. The data from Denmark and Finland are ready, the Swedish will finalise their data soon and in Norway the application to obtain these data is currently being processed," explains Prof. Anders Nyboe Andersen, past chairman of the EIM.
Due to the possibility of cross-linking ART data with data from other health registers, the researchers will be able to assess long-term morbidity in these children and compare it with appropriate control groups. "It is the long-term commitment of the EIM to expand this database to other European countries, but it will be at least a year before we can present the results to the public," Prof. Nyboe Andersen concluded.

On the way to developing a new active ingredient against chronic infections

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
