Submissions are assessed by the Editorial Board
and are subject to external peer review using the single blind method whereby the authors are blinded to the identity of the reviewers and editors.
Due to the high volume of submissions received, the Editor-in-Chief and the Editorial Board operate a rapid triage system and only the top 40% of papers undergo full external peer review. This workflow is in place to allow authors to submit to a more appropriate journal with minimal delay.
The journal aims to return a decision on a peer-reviewed paper in less than a month.
Authors who feel they have grounds to appeal a rejection decision should send a rebuttal letter to the editorial office
, detailing the reasons for the appeal. Rebuttals will be considered by the Editor-in-Chief, often in consultation with the Editorial Board Member who handled the paper. Decisions on appeals are final.

Review articles are normally by invitation and undergo peer review by experts in the field. Authors intending to submit unsolicited reviews should send an outline of the proposed article to the editorial office
Please note that systematic reviews and meta-analyses are classified as clinical studies.
Case reports will only be considered if they represent exceptional insights or advances in clinical endocrinology.
Debate articles aim to cover the latest controversies in clinical endocrinology. Debates take the format of a general introduction written jointly by the proposer and opposer, followed by two distinct sections presenting the evidence for each point of view, followed by concluding remarks. Debates are published as single articles, providing readers with an excellent overview resource for topics around which there is no current consensus. Debate articles are commissioned by the editorial board and undergo peer review by experts in the field. If you would like to suggest a debate topic please submit a brief outline to the editorial office.
Clinical Practice Guidelines
Clinical practice guidelines are produced by the European Society of Endocrinology
, either in collaboration with other Societies or independently, and are aimed at providing recommendations for patient care for specified conditions. The ESE Clinical Committee
play a leading role in the development of guidelines.
The European Society of Endocrinology’s clinical guidelines are reviewed by our members and relevant interested parties (such as patient support groups) before publication and are presented during the annual European Congress of Endocrinology. Where it is considered beneficial, patient support literature will be prepared alongside the guidelines to provide patients with assistance in understanding and managing their condition.
Position statements are submitted by professional task forces, networks or society working groups, detailing an official view on a specific issue. Statements present all relevant background information and the rationale behind any recommendations set out.
All Editorials must be a maximum 1500 words (including references, legends and tables) and 10 references.
Commentaries are typically invited by the Editor-in-Chief, although unsolicited commentaries will be considered. Commentaries are opinion articles that will examine novel concepts and findings introduced into the scientific record. They are typically no more than 2500 words in length, should have no more than eight references, and have no figures or tables.
Letters to the Editor
Letters to the Editor have a flexible format and may be published on occasion, where comments on a paper published in European Journal of Endocrinology
or a topical issue in the field are of broad interest to the readership. Authors should submit letters through the journal’s submission system
for consideration by the Editor-in-Chief.
Supplementary data too large for print publication or exceeding the bounds of the manuscript may be submitted for online publication.
Supplementary data files intended for online publication should be submitted online via ScholarOne Manuscripts as ‘Supplemental File for Review’, and referred to as supplementary data in the text:
(Supplementary Table 1)
(Supplementary Figures 1 and 2)
Supplementary information will be reviewed as part of the manuscript, evaluated for its importance and relevance and, if accepted, will be referenced in the text of the article, directing readers to the website. There is a charge
for publication of supplementary data. Should authors not wish to publish their supplementary data, they must notify the editorial office prior to acceptance.
Human Subjects Research
Authors must include a statement that consent has been obtained from each patient after full explanation of the purpose and nature of all procedures used. For research requiring ethics committee approval, please include a statement to this effect in the manuscript. Also indicate whether patient consent was obtained in line with the below policy. We will be unable to accept research papers without this statement.
Where possible, identifying information, including names, initials, or hospital numbers, should not be published in written descriptions, photographs, or pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Any identifiable patient must be shown the manuscript to be published before being asked to give consent. Authors should disclose to these patients whether any potential identifiable material might be available online or in print after publication. Informed consent should be obtained if there is any doubt that anonymity can be maintained. We no longer publish pictures with black bands across the eyes without a signed consent form, because bands fail to mask someone’s identity effectively.
Authors submitting case reports are required to state that they have obtained informed consent from the patient or the patient's guardian for publication of the submitted article and accompanying images. Authors should obtain written consent from the patient for use of potential identifiable material including photographs.
The patient (or parent or guardian) must give written informed consent for publication by signing our consent form
. Signed consent forms should then be retained in the patient's clinical notes for future reference, and a copy should be made available for review by the Editor on request.
The manuscript reporting this patient's details should state that 'Written informed consent for publication of their clinical details and/or clinical images was obtained from the patient/parent/guardian/ relative of the patient'. If the patient is deceased the authors should seek permission from a relative and include a statement to this fact. If neither the patient or a relative can be traced, we can only publish if we are satisfied the information has been sufficiently anonymised, making it impossible to identify the patient with any certainty.
Permission is not required to publish the 'recordings' listed below, provided that, the recordings are effectively anonymised by the removal of any identifying marks, and patient details (i.e. patient name, date of birth, name of hospital) from images before submission:
- Images taken from pathology slides
- Laparoscopic images
- Images of internal organs
- Ultrasound images
When such an image is accompanied by text that could reveal the patient's identity through clinical or personal detail, however, a signed consent form and declaration as listed above, will be required before publication.
Papers reporting clinical trials will only be considered if the trials have been pre-registered according to the guidelines set out in The Lancet 364 (9438) 911--912
Authors should also refer to the CONSORT 2010 Statement
, and in particular the checklist within it, when preparing manuscripts detailing clinical trials.
Authors must state the clinical trial registration number within their article.
Experiments with animals must be performed in accordance with international, national and institutional requirements. Include a statement that investigations have been approved by the local ethical committee, along with the following:
- Give the full binomial Latin names for all experimental animals other than common laboratory animals
- State the breed or strain and source of animals, and give details of age, weight, sex and housing
- Detail the procedures and anaesthetics used, including doses given
Articles will only be considered if the procedures used are clearly described and conformed with the international and national legal and ethical requirements, as well as the requirements outlined by the institution in which the work took place. A statement identifying the committee approving the study must also be included in the Methods section.
Authors are encouraged to refer to the ARRIVE guidelines
, and in particular the checklist within them, when preparing manuscripts detailing animal experiments.
Editors reserve the right to request further information on the exact procedures and ethical approval obtained as part of the review process. Papers may be rejected on ethical grounds should the editors feel the study does not adequately meet current international guidelines for humane research.
Experiments with genetically engineered mice
In inbred mice, genetic strain effects can have significant effects on phenotype. Because of this the following controls for experiments with genetically-manipulated mice should be used: parental inbred strain, or wild-type littermates.
Human genotype–phenotype association studies
Until recently almost all genotype–phenotype observations were done using candidate gene approaches. The sequencing of the human genome and the comprehensive mapping of haplotypes of human SNPs have revolutionized gene association studies, which can now be conducted through genome-wide approaches. Unfortunately, many of the reported genotype–phenotype associations are questionable, and have not been replicated. European Journal of Endocrinology
recognizes that genotype–phenotype association studies, performed by either genome-wide or candidate gene approaches, are of potential interest as a first step in the discovery process, although subsequent validation will be needed to confirm or refute the observation. However, these initial association reports must be methodologically sound. To ensure this the Journal has adopted the recommendations made by the NCI-NHGRI Working Group on Replication in Association Studies (Nature 447 (7145) 655--660
), and authors should adhere to these criteria as listed below.
These criteria are intended for studies of genotype–phenotype associations assessed by genome-wide or candidate-gene approaches:
- Statistical analyses demonstrating the level of statistical significance of a finding should be published or at least available so that others can attempt to reproduce the reported results
- Explicit information should be provided about the study’s power to detect a range of effects
- The study should be epidemiologically sound, with careful accounting for potential biases in selection of subjects, characterization of phenotypes, comparability of environmental exposures (when possible) and underlying population structure in cases and controls
- Phenotypes should be assessed according to standard definitions provided in the report
- Associations should be consistent (within the range of expected statistical fluctuation) and reported for the same phenotypes across study subgroups or across similar phenotypes in the entire study group
- Significance should not depend on altering the quality control methods beyond standard approaches that could change inclusion or exclusion of large numbers of samples or loci
- Measures to assess the quality of genotype data should include results of known study sample duplicates or publicly available samples
- The results for concordance between duplicate samples (if applicable) as well as completion and call rates per SNP and per subject should be disclosed, along with rates of missing data
- A subset of notable SNPs should be evaluated with a second technology that verifies the same result with excellent concordance, because no technology is error-free
- Associations with nearby SNPs in strong linkage disequilibrium with the putatively associated SNP should be reported (and should be similar)
- The results of replication studies of previous findings should be reported even if the results are not significant
- Testing for differences in underlying population structure in case and control groups should be performed and reported
- Appropriate correction for multiple comparisons across all statistical tests examined should be reported. Comparison to genome-wide thresholds should be described. Similarly, for bayesian approaches, the choice of prior probabilities should be described
Wherever possible, manuscripts must be prepared in accordance with approved gene nomenclature.
- In gene and protein symbols, substitute Greek letters with the corresponding roman letter, e.g. TGFBR2 not TGFβR2
- Avoid hyphens unless they are part of the approved symbol, e.g. IGF1 not IGF-1
- Use arabic rather than roman numerals, e.g. BMPR2 not BMPRII
Follow species-specific formatting standards as follows:
Humans, non-human primates and domestic species
- Gene symbols should be in italics with all letters capitalised, e.g. SOX2
- Protein designations should be the same as the gene symbols but not italicised, e.g. SOX2
- Please use symbols approved by the HUGO Gene Nomenclature Committee (HGNC)
Mice and rats
- Gene symbols should be in italics with only the first letter capitalised, e.g. Sox2
- Protein designations should be the same as the gene symbols except that all letters should be capitalised and in roman (i.e. not italicised), e.g. SOX2
- Please use symbols approved by the International Committee on Standardized Genetic Nomenclature for Mice and the Rat Genome and Nomenclature Committee, which can be queried at the MGI website
Digital image integrity
No specific feature within an image may be enhanced, obscured, moved, removed, or introduced. The groupings of images from different parts of the same gel, or from different gels, fields or exposures must be made explicit by the arrangement of the figure (e.g. using dividing lines) and in the text of the figure legend. Adjustments of brightness, contrast, or colour balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. Nonlinear adjustments (e.g. changes to gamma settings) must be disclosed in the figure legend. Adjustments should be applied to the entire image. Threshold manipulation, expansion or contraction of signal ranges and the altering of high signals should be avoided.
Microscope images should be made available to referees in images that are at least 300 dpi at the size which they will be published. 'Pseudo-colouring' and nonlinear adjustment (for example 'gamma changes') are only allowed if unavoidable and must be disclosed.
Digital image guidelines
Recognizing that the inappropriate use of computer software for digital image analysis and processing can raise concerns, the journal has produced the following requirements for the representation of research data:
- No specific feature within an image may be enhanced, obscured, moved, removed, or introduced
- Adjustments of brightness, contrast, or colour balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. Any such adjustments should be applied to the entire image
- Threshold manipulation, expansion or contraction of signal ranges and the altering of high signals should be avoided
- The legend to a digital image should state if and what digital modifications were applied
The following guidelines apply to digital images that that result from gel electrophoresis and blotting procedures:
- Band intensity should be quantified from several independent experiments. If only a "typical" experiment is shown in the figure, authors should be prepared to provide unprocessed images of gels or blots at the request of the Editor-in-Chief.
- Extensively cropped images are not acceptable. Images can be cropped to enhance clarity of presentation, but should always contain at least two markers (one with a smaller, one with a larger molecular size than the band of interest) with their molecular sizes indicated.
- Producing spliced images by combining lanes from gels or blots from different experimental runs should be avoided. A lane containing markers should be on the same gel for each run. If spliced images are presented, the vertical lanes obtained from gels or blots from different experimental runs should be clearly demarcated with lines.
- As the validity of immunoblots relies heavily on antibody specificity, an appropriate control (tissue from knockout mice or protein knockdown in cell lines) must be included, or alternatively a reference should be given in the methods section referring to such a control (Saper 2009; Burry 2011).
- The reuse of images of loading controls from other experiments or previous publications is unacceptable.
Burry RW 2011 Controls for immunocytochemistry: An update. Journal of Histochemistry & Cytochemistry 59 6–12. (doi:10.1369/jhc.2010.956920)
Saper CB 2009 A guide to the perplexed on the specificity of antibodies. Journal of Histochemistry & Cytochemistry 57 1–5. (doi:10.1369/jhc.2008.952770)
It is the author’s responsibility to document that the results are reproducible and that the differences found are not due to random variation. No absolute rules can be applied but, in general, quantitative data should be from no fewer than three replicate experiments. Appropriate statistical methods should be used to test the significance of differences in results. The term ‘significant’ should not be used unless statistical analysis was performed, and the probability value used to identify significance (e.g. P < 0.05) should be specified.
When several t-tests are employed, authors should be aware that nominal probability levels no longer apply. Accordingly, the multiple t-test, multiple range test, or similar techniques to permit simultaneous comparisons should be employed. Also, in lieu of using several t-tests, it is often more appropriate to utilize an analysis of variance (ANOVA) to permit pooling of data, increase the number of degrees of freedom, and improve reliability of results. Authors should use appropriate nonparametric tests when the data depart substantially from a normal distribution.
In presenting results of linear regression analyses, it is desirable to show 95% confidence limits.
When data points are fitted with lines, specify the method used for fitting (graphical, least squares, computer program). If differences in slopes and/or axis intercepts are claimed for plotted lines, these should be supported by statistical analysis.
Give sufficient details of the experimental design and analysis so that the reader can assess their adequacy and validity for testing the hypotheses of interest. In particular:
- Describe the numbers of experimental units used and the way in which they have been allocated to treatments
- Justify the omission of any observations from the analysis
- Describe methods of analysis precisely and state any necessary assumptions, as these may affect the conclusions that can be drawn from the experiment
