Is your paper suitable for BJOG?

BJOG welcomes submissions of papers on all subjects relating to women's health. We give priority to papers containing original data, systematic reviews and commentaries suggesting innovative approaches to women's health problems. We have a global remit and publish papers from all around the world, including from both developed and developing countries.

Our readership is predominantly clinical but we welcome basic science submissions that have clinical implications. We are happy to consider qualitative studies provided they are written with the clinician in mind. The best way of appreciating the sort of papers we publish is to read some of our recent issues. We particularly appreciate a clear writing style with a minimum of jargon.

Initial assessment of submissions is done by our three Deputy Editors-in-Chief, who reject about 20% of papers at that time if they consider them not appropriate for our readership. This means you will get a quick assessment of your paper’s suitability for the journal, giving you the opportunity to submit elsewhere with a minimum of delay if it is not suitable. Papers judged to be on a suitable topic will then be allocated to an editor for more detailed assessment.

A further 10% will be rejected at this point if the presentation, the methodology etc are judged to be inadequate. The remaining 70% will then be sent to referees, and following receipt of their reports, if one or more of the referees recommend publication, the paper will then be discussed between editors, with the final decision being based on at least a majority of five opinions. We currently accept about 15% of submitted papers.

For our editorial process please see the following flow chart.

How to submit your paper to BJOG

Submissions to BJOG must be made online through Allen Track: http://bjog.allentrack.netPaper manuscripts and email submissions are not accepted.

Authors must register on the site. Once this has been done you can use your login and password to access your home page (please avoid creating duplicate accounts). From the home page, you will have access to the status of your manuscripts throughout the editorial process and, therefore, you need to retain your login and password for future reference.

It is essential that the email address for the corresponding author is entered correctly and is updated via the home page if it becomes invalid at any time. All correspondence regarding the submission will go to this email address.

If you have any problems accessing your AllenTrack home page please email:

Before submitting your manuscript please read both these instructions to authors and the BJOG editorial policies.

Once you have logged into AllenTrack click on ‘Submit Manuscript’. After reading the instructions on this page you will need to select the appropriate article type at the bottom of the page and click ‘Continue’. You will be asked to enter specific information about the manuscript (e.g. title, type of manuscript, clinical category) prior to uploading your actual manuscript files. There are also publication ethics questions to be answered. Please read carefully the authorship criteria in BJOG editorial policies

You will upload manuscript files from your computer as the last stage of the submission process. Once your files are uploaded to the database, they will be converted by the system to PDF files that can be viewed, downloaded and printed.

• Manuscript files and your cover letter should be in MS Word or RTF format.
• Table files can be submitted as MS Excel files or MS Word files.
• Figures must be submitted separately from the text as TIFF, EPS or JPEG files. They should be in order and clearly labelled.

Converting most files takes under ten minutes, but sometimes a large file will take longer. Conversion time also depends on the speed of your connection. The system will ask you to confirm that all files have converted correctly - please check your files to make sure that the system has converted each element properly. Your paper will be considered officially submitted only after the system receives this confirmation when you click on ‘Approve the Converted Files’.

If your submission is not in the correct format, the file will be returned to your home page for you to make any necessary corrections, as detailed in an email from

Please follow the instructions below to increase the chances of your paper passing this initial quality control stage first time, avoiding delays to your submission. Once a paper has been correctly submitted through the online system, it is assigned a tracking number and is accessed by one of our Deputy Editors-in-Chief.

How to improve your paper

Writing style and terminology

Manuscripts should be written in clear concise English. If you are not a native English speaker you may wish to have your manuscript professionally edited before submission. For more information regarding this see Wiley-Blackwell Author Services

Some style guidelines specific to BJOG can be found below:

• 'Fetus' and 'fetal' should be spelt without 'o', and 'ise' spellings are preferred to 'ize' spellings.
• Numbers one to ten should be spelled out; for more than ten people, objects, days, months, etc., use Arabic numerals.
• 'Women' is generally preferred to 'patients' when reporting on obstetrics.
• 'Termination of pregnancy' is preferred to 'therapeutic abortion' and 'miscarriage' is preferred to 'spontaneous abortion'.
• Authors should always use the generic names of drugs unless the proprietary name is directly relevant.
• Any specialised equipment, chemical or pharmaceutical product cited in the text must be accompanied by the name, city and country of its manufacturer.
• Any abbreviations or acronyms used should be defined at first use in the main body of the article.

Please refer to this paper for terminology of lower urinary tract function and this paper for early pregnancy events.

The following paper may also be useful: Use of Race and Ethnicity in Biomedical Publication (J. Kaplan, T Bennett, JAMA. 2003:289(20): 2709-2716.)

Further guidance on scientific writing can be found on the Equator Network website.

Search engine optimization

To help improve the search engine ranking of your paper you should ensure you optimize your title and abstract. For more information and tips on how to do so please refer to Wiley Blackwell Author Services or view the following SEO tips sheet [PDF]. 

Study design and statistics

The design of investigations, methods of analysis and the source of data should be described in sufficient detail to permit the study to be repeated by others, and must include specification of all statistical methods. Measurements should be expressed in SI units with the exception of haemoglobin (g/dL) and blood pressure (mmHg).

If human participants were involved, manuscripts must be accompanied by a statement that the experiments were undertaken with the understanding and appropriate informed consent of each. If experimental animals were used, the materials and methods (experimental procedures) section must clearly indicate that appropriate measures were taken to minimize pain or discomfort, and details of animal care should be provided.

Supporting Information (online only)

Please note that the length of papers in the printed journal is restricted, and so authors should consider what information can be published on the online version, as Supporting Information.
Supporting Information must be important, ancillary information that is relevant to the parent article but which is not essential in the print edition of the journal. A maximum of 4 tables and figures can appear in print, and each should be no longer than 1 page. All other tables and figures can appear online only as Supporting Information.

All supporting information must be referred to in the manuscript, and labelled Table S1, Table S2, Figure S1, Video S1 etc. Please note that tables, figures etc. have separate numbering sequences. Please do not include supporting information within the main manuscript file, but upload as Supporting Information file(s). Videos will be included as supporting information. For further instructions please refer to Wiley Blackwell Author Services.

Supporting Information files are published online only. Supplementary Information files are not published. Therefore ICMJE forms and extra tables and figures should be submitted as Supporting Information files. Ethics approval letters, PRISMA/MOOSE checklists ect should be uploaded as Supplementary Information.


The BJOG editorial team are committed to optimising the discoverability of your article, and therefore encourage the submission of videos relevant to your paper. The readers of BJOG are busy professionals and access content for different reasons, from keeping up to date with the latest original research to preparing for a lecture or journal club. To help meet these needs, we have developed different routes to BJOG content. All videos submitted with a submission will be available as supporting information if the paper is accepted. In particular we encourage the submission of videos for surgical technique papers.

We also accept video abstracts from authors. These will be available on our website and our dedicated album on Vimeo, and promoted across social media to increase the visibility of the work. They could also be used for promotional purposes in other marketing material. We expect video abstracts to increase the impact of the work and result in more downloads. Ideally, the video should be no longer than 60 seconds, and answer 3 questions:

1. Why was the study carried out?
2. What are the main findings?
3. What are the implications for future research and practice?

Please check our guidance on how to create a video abstract for your BJOG paper.

Good reporting guidelines

The Scientific Editors reserve the right to edit a manuscript for grammar, house style, scientific and statistical clarity, and overall length, while maintaining the scientific accuracy of the report. Authors may be asked to incorporate editorial amendments of spelling, grammar, house style and to check minor inconsistencies in the text or reference list, together with scientific and/or statistical corrections, before returning a revised manuscript for final approval by the Editor. Failure to make either scientific/statistical or editorial amendments could result in delayed acceptance and publication.

Once the manuscript has been typeset the corresponding author will receive an email alert that their proofs are ready. A working email address must therefore be provided for the corresponding author. This email will contain a link to a web site and the proof can be downloaded as a PDF file.

Acrobat Reader will be required in order to read this file. This software can be downloaded (free of charge) from the following website: This will enable the file to be opened, read on screen and edited electronically. You may prefer to print the pdf and add your corrections offline.

Further instructions will be sent with the proof. To avoid publication delays proofs should be checked immediately and returned by email, fax or by express post to the address indicated on the proofs. Do not send proofs to the BJOG editorial office. Telephone corrections will not be accepted.

Authors are advised that they are responsible for proofreading of the text, references, tables and figures for absolute accuracy. New material cannot be accepted at this stage and substantial rewriting of paragraphs is not permitted. Should authors insist in doing so, then the costs will be charged to the author and the journal will not be responsible for typesetting errors arising from these changes.

Early View

Early View articles are complete full-text articles published online in advance of their publication in a printed issue. Articles are therefore available as soon as they are ready, rather than having to wait for the next scheduled print issue. On average it takes 6-8 weeks from being sent to production (usually straight after acceptance) to a paper appearing online. Early View articles are complete and final. They have been fully reviewed, revised and edited for publication, and the authors' final corrections have been incorporated. Because they are in final form, no changes can be made after online publication. They are given a Digital Object Identifier (DOI), which allows the article to be cited and tracked. After publication, the DOI remains valid and can continue to be used to cite and access the article.


Authors should advise the publisher ( of corrections, apologies and retractions to the publisher who will publish them as the next available opportunity. The Editor-in-Chief may be consulted as appropriate.

Author services

Online production tracking is available for your article through Wiley-Blackwell Author Services.

Author Services enables authors to track their article - once it has been accepted - through the production process to publication online and in print. Authors can check the status of their articles online and choose to receive automated e-mails at key stages of production so they don't need to contact the production editor to check on progress. 

Visit the Author Services area for a wealth of resources including FAQs and tips on article preparation, submission and more.


Free access to the final PDF offprint of your article will be available via author services only. Please therefore sign up for author services if you would like to access your article PDF offprint and enjoy the many other benefits the service offers.
