Researchers at the NIPH’s Medical Birth Registry and the University of Bergen have collected data on all first-time births from 1967-1996 and subsequent births until 2003. This covers nearly 600 000 births, so the results are statistically significant.
– Our finding confirms that from other studies; that women who give birth to their first child by Caesarean section less frequently have child number two and three than women who give birth in the normal way. We have looked further to see which births the reduced fertility concerns, says researcher and head physician Dr Kari Klungsøyr from the Medical Birth Registry.
The study is published in the journal Obstetrics and Gynecology and is a joint effort between the Department of Public Health and Primary Health Care at the University of Bergen and the NIPH. The main author of the publication is Mette Tollånes from the University of Bergen.12 percent lower
The figures are as follows for women who had their first child between 1982 to 1996, who were then monitored until 2003:Probability of having child number two for women who had a Caesarean section: 12 percent lower than for women who gave birth vaginally.
For the sub-group who had a child who was stillborn or died in the first year: probability of having child number two was the same as for women who gave birth in the usual way.
- How can we explain this finding?
- We do not think it has anything to do with the medical reason for the Caesarean section, or any physical consequences of the operation. We can ask ourselves if it is such that if the women have had the child they want, maybe some cannot bear the thought of pregnancy, birth and any new operational procedures, says Klungsøyr.Reference

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
