The research group from the University of Valencia (UV) that carried out the bibliometric research sought to identify the most productive authors and institutions between 2003 and 2005, as well as the composition of scientists in collaborative projects between authors and centres publishing their work in the leading reproductive biology journals.
The study has been recently published in Fertility and Sterility. The scientists appearing on the league table “can be considered as the elite in terms of research in the area; in other words they are at the cutting edge of scientific developments in this discipline”, Gregorio González-Alcaide, lead author of the study and a researcher at the López Piñero Institute of the History of Medicine and Science, a joint UV and CSIC centre, told SINC.
In total, the researchers studied 4,702 papers, of which 96.75% were the written in collaboration between two or more authors, while 73.73% of the research stemmed from collaboration between institutions. The authors identified 106 authors who had published more than nine studies, and calculated an average number of 5.24 researchers per study.
On this basis, Antonio Pellicer Martínez, Dean of the Faculty of Medicine and Odontology, and chair in Obstetrics and Gynaecology at the University of Valencia (UV) took fourth position, with 30 pieces of research published and 72 collaborations. The other Spaniard, in the number nine slot, is Carlos Simón, chair in Obstetrics and Gynaecology at the UV and the first researcher in Spain to have obtained cell lines from human embryo stem cells, with 24 papers. He is a researcher at the Valencian Stem Cell Centre and a member of the Valencian Infertility Institute (IVI).
Spain, among the top 20Spain takes the number 11 spot in terms of production of scientific research in the field of reproductive biology, with 159 studies published between 2003 and 2005, or 2.82% of total world production. In terms of work carried out, Spain undertook 100 collaborative projects, with the United States being the most frequent partner, in 19 projects. The United States and the United Kingdom are world leaders in terms of scientific production, with the US producing 1,541 papers (27.32% of total world production). These two countries “have led the league tables of absolute productivity (number of studies) in the area since the 1990s, although research is now emerging strongly in countries such as Canada and the People’s Republic of China”, points out
In terms of Spanish scientific centres, the Valencian Infertility Institute (IVI) is the most productive Spanish institution in the field of reproductive biology, occupying the number 33 spot at international level. France’s National Institute for Health and Medical Research and the University of Texas, USA, lead the productivity ranking, with 94 and 65 studies, respectively.
The bibliometric leader
At 1,491 pieces of research, the American journal Fertility and Sterility has published more studies within this discipline than any other scientific magazine. It is followed by the British journal Human Reproduction, with 1,400 and the highest average rate of papers per issue, and Biology of Reproduction, with 1,322.
The researchers chose reproductive biology as a subject to look in more depth at ‘scienciometric’ studies related to scientific sociology, because it is “an area of knowledge with great social relevance, and which has undergone significant growth over recent decades”, explained González.
During the bibliometric analysis, however, the researchers found some limitations in the quality of data sources (authors who do not always sign their studies in the same way), the coverage of the study, (which does not include all research within this field), and the way in which the study included analysis of co-authorship (with no uniform criterion for identifying networks of authors).

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
