Today, an intriguing paper published in Europe's leading reproductive medicine journal Human Reproduction  reveals for the first time the reasoning behind the MRC's much-criticised decision.
The authors of the research, led by Martin Johnson, Professor of Reproductive Sciences at the University of Cambridge, and funded by the Wellcome Trust, write: "The failure of Edwards' and Steptoe's application for long-term support was not simply due to widespread establishment hostility to IVF. It failed, we argue for more complex reasons".
These reasons included:
A strategic error by Edwards and Steptoe when they declined an invitation from the MRC to join a new, directly funded Clinical Research Centre at Northwick Park Hospital, Harrow. They preferred to ask for long-term grant support at the University of Cambridge, but this meant they had to compete for funding with all the other research projects bidding for MRC support. This was also difficult for Cambridge, which lacked the back-up of an academic Department of Obstetrics and Gynaecology at that time.
Most of the MRC referees who were consulted on the proposal considered, in line with government policy, that it was more important to limit fertility and the growth of Britain's population than to treat infertility. Treating infertility was seen as experimental research rather than as therapeutic.
Concerns about embryo quality (would babies be born with severe abnormalities?) and patient safety made the referees doubt the wisdom of funding embryo transfer without conducting studies in primates first.
Edwards' and Steptoe's high profile in the media antagonised the referees who strongly disapproved of this method of public discussion of the science and ethics of treating infertility.
An additional obstacle for Edwards and Steptoe was that they were seen by the MRC as not being part of the "medical establishment". In their paper, Prof Johnson and his colleagues write: "Steptoe came from a minor northern hospital, while Edwards, though from Cambridge, was neither medically qualified nor yet a professor." Edwards had a PhD in developmental genetics from the Institute of Animal Genetics at the University of Edinburgh, then the leading UK centre in the field.
Prof Johnson said: "The MRC's negative decision on funding of IVF, and their public defence of this decision, had major consequences for Edwards and Steptoe and set MRC policy on IVF research funding for the next eight years. This decision was only reversed after the birth of two healthy babies from seven IVF pregnancies. In its 1978/79 Annual Report, the MRC announced a change of policy and from that time on became a strong and major supporter of research on human IVF and human embryos, although curiously not research follow-up of IVF pregnancies."
Since then, an estimated 4.3 million babies have been born worldwide with the help of a range of fertility treatments developed since the birth of Louise Brown .
Prof Johnson and his colleagues, Sarah Franklin, Matthew Cottingham and Nick Hopwood, spent three years studying the MRC records at the National Archives at Kew in Surrey, and also documents from the Royal College of Obstetricians and Gynaecologists, Addenbrooke's Hospital, Cambridgeshire County Council and Cambridge University Library. Bob Edwards' wife, Ruth, gave them access to his private papers, and the researchers also interviewed many of the key players involved in the MRC's decision in 1971 not to fund the research.
In an accompanying editorial , Professor John Biggers from Harvard Medical School (USA), writes: "By taking us back 40 years, the authors have demonstrated the importance of understanding a decision in light of the culture and circumstances at the time the decision was made. Although the grant was rejected, Edwards' and Steptoe's visions and persistence have benefited an enormous number of infertile people, both male and female."
Prof Johnson said: "The story of the MRC's non-funding of IVF belies the cliché that science 'races ahead' of society. Similarly, the standard view, that ethical consideration of bioscience and biomedicine can only ever be reactive, is contradicted by the evidence of extensive ethical debate surrounding the prehistory of clinical IVF – most of it actively stimulated by Edwards himself. Although attitudes to medical scientists in the media have changed significantly since the 1970s, scientists and clinicians engaged in high-profile work still face a dilemma. If they encourage public discussion of their work – which they may see as both necessary to securing support and desirable to ensure full ethical debate – must they inevitably weaken their standing among their peers?
"Finally, our case study questions the myth of two courageous mavericks pitted against a conservative establishment. This myth does capture important elements of truth: Edwards and Steptoe were outsiders and did pioneer—against prevailing wisdom—new ideas, therapies, values, public discourses and ethical thinking. But the process of decision-making was more complex than the myth allows. Our research provides a fuller understanding of what happened at the birth of the IVF revolution."
Prof Johnson believes that today the decision-making processes involved in awarding funding for projects are more open and transparent, with discussion in the wider community and in the media actively welcomed, as was the case with the two Human Fertilisation and Embryology Acts in 1990 and 2008.
"A continuing problem, however, is more to do with the fact that there are some very fashionable topics that can create a buzz and attract huge research interest and funding, sometimes in disproportionate amounts; then it was fertility limitation, more recently genome sequencing would be an example. This can leave other Cinderella topics languishing in the ashes, with little financial support, even though they might well play an equally, if not more, important role in patient welfare."

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
