Dr Bea Lintsen, a physician at the Department of Obstetrics and Gynaecology, Radboud University Nijmegen Medical Centre (The Netherlands), and her colleagues used questionnaires to assess the levels of psychological distress in 783 women at two points before and during fertility treatment.
Results from the 421 women who completed both questionnaires showed that levels of depression or anxiety either before or during fertility treatment had no influence over cancellation rates and did not predict pregnancy rates either.
Until now, studies of the links between anxiety and depression and the success of fertility treatment have been inconclusive. Dr Lintsen believes hers is the largest prospective study yet to look at the influence of distress on the outcome of a first IVF or ICSI treatment, and that the findings are reliable. However, she and her colleagues say the associations between psychological factors and pregnancy rates after IVF are complex and require further research into mediating factors such as lifestyle and sexual behaviour.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
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...
