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

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
