Author Guidelines

The International Journal of Gynecology and Obstetrics (IJGO)—which is the official publication of the International Federation of Gynecology and Obstetrics (FIGO)—publishes articles on all aspects of basic and clinical research in obstetrics/gynecology and related subjects, with emphasis on matters of worldwide interest. See journal homepage for the IJGO Statement of Purpose.

The IJGO will consider for publication unsolicited submissions of the following: Clinical Articles; Review Articles; and Brief Communications (including Case Reports).

The requirements of the IJGO are in accordance with the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" published by the International Committee of Medical Journal Editors (ICMJE).

It is the general policy of the IJGO to ensure that papers from individual low- and middle-income countries include local co-authors and collaborators. These research and academic colleagues should be identified early and be involved in research question development, Institutional Review Board approval, data collection and analysis, and manuscript preparation. Principles of community-based participatory research should be strongly considered. Co-authors should satisfy accepted requirements for authorship. The Editorial Board believes this supports FIGO priorities for capacity building and prevents any perception that data or research is being co-opted by scholars from high-income countries. Multi-country studies or analyses of internationally available databases do not necessarily have to meet this requirement and will be considered individually by the Editors, as are all submissions. Any questions or issues can be sent to the Editorial Office at prior to submission or may be raised during the editorial process.

All manuscripts should be prepared according to the guidelines detailed below. Any manuscript that has not been formatted per the IJGO requirements will be returned to the author. All manuscripts should be created and submitted in Word format.


Authors must submit manuscripts online through Editorial Manager (EM). Hard-copy submissions will not be considered or returned.

If you are using EM for the first time, please click the ‘Register’ button at the top of the page and enter the requested information. If you are a returning user, please click the ‘Login’ button at the top of the page and enter your username and password.

To submit a manuscript: please click the ‘Submit a manuscript’ button at the top of the page. You will then be asked to log in using your username and password. If you have not already registered with the system you will need to do so before submitting your manuscript. For more information on the system, please click here.

Please have the following information and documentation ready when you submit your manuscript via EM:

  • Each author's name, address, and email address.
  • Each author's affiliation and qualifications.
  • The name of the author who is to deal with correspondence and proofs.

Authors should send queries concerning the submission process or journal procedures to

Once submitted, manuscripts undergo initial screening by the editorial staff and editors. To ensure timely processing of the large number of submissions received, papers that do not meet the journal's submission requirements, standards, or topic suitability will be rejected at this stage, without peer review, and the authors will receive prompt notification. All other papers will undergo peer review.

Authors can check the status of their manuscript during the review process by logging into EM. All communication, including notification of the editor's decision and requests for revision, is via email.

Please ensure that the email address of the corresponding author is entered correctly and up-to-date on EM. All correspondence regarding the submission will be sent to this email address.


The Author(s) Guarantee Form and the Submission Requirements Form (both available on EM at the "Select Article Type" stage of the submission process) must be completed and submitted with each manuscript. The article's corresponding author is responsible for ensuring that all of the necessary forms are completed accurately.

2.1. Author(s) Guarantee Form

In the Author(s) Guarantee Form, the article title and the names of all authors must be listed as they appear in the manuscript. The author(s) must guarantee:
(1) that all authors have met the criteria for authorship and have participated sufficiently in the work to take responsibility for it;
(2) that all authors have reviewed the final version of the manuscript and approve it for submission to the IJGO;
(3) that neither this manuscript nor one with substantially similar content by the authors has been published elsewhere or is being considered for publication elsewhere;
(4) that the manuscript has been submitted with the full knowledge and approval of the institutions or organizations given as the affiliation(s) of the author(s);
(5) that the authors have informed the editor in a cover letter and in the manuscript itself of any conflicts of interest; and
(6) that the corresponding author affirms the manuscript to be an honest and transparent account of the study being reported.

In line with ICMJE standards, the IJGO’s criteria for authorship are as follows:
(1) Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
(2) Drafting the work or revising it critically for important intellectual content; AND
(3) Final approval of the version to be published; AND
(4) Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Submission of multi-authored manuscripts implies the consent of each of the authors.

2.2. Submission Requirements Form

In the Submission Requirements Form, authors must check the boxes relevant to their submission. The checklist must be completed by the author(s) for inclusion in the submission.


All submissions must be accompanied by a cover letter. The letter, which should be addressed to the Editor (Dr Richard Adanu), should briefly describe the study/paper and state the word count, in addition to any conflicts of interest for any of the authors.

If copyright permission is required to reproduce any material in an article, include confirmation in the cover letter that such permission has been obtained from the copyright holder (see section 5.11.2).

If any writing assistance—other than copy editing—was provided, details (including information about any funding for such assistance) must be given in the cover letter.


4.1. EQUATOR Network

The EQUATOR Network website explains what reporting guidelines are and why they are needed. It contains links to the checklists described below and provides useful guidance for authors and editors.

4.2. Clinical trials

Submission of clinical trials must include reference to ethics approval (or explanation of why ethics approval was not received). Authors must consult the CONSORT statement and checklist and submit a CONSORT flow chart as an editable figure in Word/PowerPoint format.

Information regarding power calculations must be included (see section 5.4.1).

4.2.1. Clinical trial registration

In compliance with ICMJE requirements, all clinical trials must be registered in a public trials registry.

The ICMJE defines a clinical trial as “any research project that prospectively assigns people or a group of people to an intervention, with or without concurrent comparison or control groups, to study the cause-and-effect relationship between a health-related intervention and a health outcome.”

Registration should occur prospectively, before or at the time of enrolment of the first patient.

Suggested registries can be found here:

In line with ICMJE standards, purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

Please consult the ICMJE website for further information on clinical trial registration.

The clinical trial registration information should be included at the end of the abstract of the submitted manuscript.

4.3. Review articles

Reviews based on the following recommended guidelines and checklists will be given preference. Systematic reviews and meta-analyses should follow the PRISMA guidelines.

Meta-analyses of observational studies should follow the MOOSE guidelines.

The IJGO endorses the use of the GRADE system for grading evidence when recommendations are made as a result of a systematic review.


Manuscript text should be in English (US spelling), double-spaced, font size 12, in Arial font.

5.1. First page

The first page of the manuscript should contain the following: (1) title; (2) full names of authors (6 maximum, although listing more authors may be considered on an individual basis if authorship requirements have been met and a request has been included in the cover letter); (3) affiliations of authors (i.e. department, section or unit of an institution, hospital or organization, city, and country where it is located; please note that street name/numbers are not required); (4) full contact details (postal address, email address) of the corresponding author; (5) a list of up to 8 keywords for indexing and retrieval; (6) synopsis (no longer than 25 words, stating the primary conclusion of the paper).

Footnotes linking author names to affiliations should be listed as 1,2,3 etc., rather than *,†,‡ or a,b,c etc.

The first page should also list the type of article: Clinical Article; Brief Communication; or Review Article.

5.2. Abstract

5.2.1. Clinical articles

A structured abstract not exceeding 200 words is required for all full-length clinical articles. It should contain all and only the following headings: Objective; Methods; Results; and Conclusion.

The Objective reflects the purpose of the study: that is, the hypothesis that is being tested.

5.4. Power calculations, statistics, and reporting of numbers

5.4.1. Power calculations

Where appropriate (e.g. for clinical trials), power calculations should be performed as part of the study design, and a statement providing the power of the study should be included in the Materials and methods. Authors should state how the power calculation was determined, including what type of difference the calculation was powered to detect and on what studies the numbers are based.

5.4.2. Statistics

The statistical tests used and the significance level set should be listed in the methods for all studies that employed statistical analysis. Information regarding the statistical software programs used should be included in the methods: for example, “SPSS version 20 (IBM, Armonk, NY, USA).” This information should not be included in the reference list.

P values should be provided where calculated. The largest P value that should be expressed is P>0.99. The smallest P value that should be expressed is P<0.001.

For measures of effect (e.g. relative risks, risk ratios, odds ratios), authors should also report confidence intervals (e.g. 95%) so that the precision of the effect estimate can be assessed.

5.4.3. Reporting of numbers

Authors are urged to ensure that all reported numbers are accurate and listed consistently throughout the manuscript, tables, and figures.

All clinical trials should include the results of intention-to-treat analysis, and all surveys should include response rates.

5.5. Ethics approval and informed consent

Studies of patients, patient records, or volunteers require Ethics Committee approval and informed consent.

5.5.1. Ethics approval

Include a statement in the methods that the research protocol was approved by the relevant Institutional Review Board or Ethics Committee before the study began; if such approval was not needed/obtained, include an explanation. Authors must provide copies of the appropriate documentation if requested.

5.5.2. Informed consent

Include confirmation in the methods that all human participants gave written informed consent before the study began; if consent was not needed/obtained, include an explanation. Authors must provide copies of the appropriate documentation if requested.

Each author’s individual contributions should be listed in support of their right to authorship. Their role in the design, planning, conduct, data analysis, and manuscript writing should be stated.

5.7. Acknowledgments

Sources of funding should be acknowledged by the author(s), along with the names of individuals who do not fulfil the criteria for authorship, but who have made a substantial contribution to the manuscript. Please note that only named individuals can be included. The corresponding author must verify that permission has been obtained from individuals named in the Acknowledgments; such permission does not need to be submitted to the journal but should be available if requested.

5.8. Conflict of interest

A conflict-of-interest statement must be included in the cover letter and before the reference list in the manuscript. It should list any relationships (for any author) that may be deemed to influence the objectivity of the paper and its review, or state that no such relationships exist. Commercial associations, either directly or through immediate family, in areas such as expert testimony, consulting, honoraria, stock holdings, equity interest, ownership, patent-licensing situations or employment that might pose a conflict of interest should be stated. Conflicts for other reasons, such as personal relationships or academic competition, should also be stated.

5.9. References

The number of references should not exceed 25 for clinical articles, 40 for review articles, and 4 for brief communications; in general, they should be limited to the past decade.

Text references should be indicated by Arabic numerals in square brackets on the line (not superscript): for example, [1–4] and [1,5,11,17]. To avoid any delays in the editing process, authors must make every effort to ensure that each reference is correct and complete.

All references must be in English. Citation information of those originally in other languages must be translated into English in the reference list. The IJGO should be cited as Int J Gynecol Obstet in the reference list.

Numbered references to personal communications, unpublished data, statistical software, or manuscripts that have not been accepted for publication (i.e. "submitted" or "under consideration") must not be included. Reference to such material, if required, can be incorporated at the relevant location in the text.

If bibliographic software has been used for managing the reference list (e.g. EndNote or Reference Manager), the reference list and citations must be unlinked before submission.

5.10. Tables

Each table should be titled, numbered (with Arabic numerals), and placed on a separate page after the reference list (not embedded within the main text).

All tables must be created and submitted in editable Word format. Only standard, universally understood abbreviations should be used. Authors should prepare tabular material in an easily readable form, eliminating tables presenting information that can easily be incorporated into the text. All tables must be cited in numeric order in the main text as "Table 1" etc.

Use the Word table function (not the "enter" key, spaces, or the "tab" function) to create a separate cell for each table entry.

Footnotes to tables should be listed as a,b,c etc., rather than *,†,‡ etc.

If tables are deemed to be too large or there are too many, they may be published as online-only supporting information (see section 5.12).

5.11. Figures and photographs

Advice on the preparation of electronic artwork can be found here.

Figures and photographs should be submitted as separate figure files (not embedded within the manuscript file), preferably in TIFF or JPEG format (at least 300 dpi). CONSORT flow charts should be created and submitted as editable Word/PowerPoint files. All figures must be cited in numeric order in the main text as "Figure 1" etc.

If labeling images, use lettering that remains clearly readable even after reduction to approximately 66%.

There are no charges for color figures.

5.11.1. Figure legends

For every figure, a titled legend must be provided in the manuscript file after the reference list; legends should be numbered consecutively in the order of their citation using Arabic numerals.

5.11.2. Figure permission

All authors wishing to use figures (or any material) that have already been published must first obtain the permission of the original author and publisher and/or copyright holders, in addition to giving precise reference to the original work. This permission must include the right to publish in electronic media. Confirmation should be included in the cover letter (the actual permission correspondence from the copyright holder does not need to be submitted).

5.11.3. Photograph/video consent

If photographs or videos of identifiable people are used, authors must obtain and submit a signed statement of informed consent from the identifiable person(s) or their next of kin. Authors should not try to conceal identity with black bars over eyes etc.

5.12. Supporting information

Authors may submit supporting information such as additional tables and figures, animations, presentations, and short videos. Supporting information will be hosted online only (it will not appear in the print version).

The submission of videos and other media is strongly encouraged.

Supporting information will not be edited or formatted but the editors and reviewers may suggest changes. All patient/participant identification must be removed or informed consent must be obtained from the identifiable person(s) or their next of kin (see section 5.11.3).

All supporting information should be cited in the main text of the article as “Table S1”, “Figure S1”, “Movie clip S1”, etc.

Supporting information will not be accepted if the associated manuscript is rejected.


Papers are published in English, using US spelling. The editors reserve the right to make any necessary editorial changes.

6.1. Numerals

Arabic numerals should be used for weights, measures, percentages, and degrees of temperature. Weights and measures should be abbreviated according to the International System of Units (SI) or non-SI units mentioned in the SI, followed by conventional units in brackets on first mention. Provide percentages after numerals throughout.

6.2. Drugs

Give generic names of all pharmaceutical preparations and, where appropriate, include the trade name and manufacturer's name and address in parentheses. Review drug names and dosages with care. The author is responsible for all recommended dosages.

6.3. Manufacturer information

Give the manufacturer's name and address (in parentheses) following the name of any instruments or equipment cited by brand name. Do not include the trademark or registered trademark symbol.

6.4. Plagiarism

Plagiarism entails the "use or close imitation of the language and thoughts of another author and the representation of them as one's own original work." Self-plagiarism, a form of misconduct in which an author reuses his/her previously written text, data, or ideas, wholly or in part, without indicating previous dissemination, will also be considered plagiarism by the IJGO. Verbatim copying of sentences, even if a citation is provided (unless the sentence appears in quotation marks), is considered to be plagiarism. Papers are checked for plagiarism (including self-plagiarism); if plagiarism is detected, action will be taken following the Committee on Publication Ethics guidelines.

6.5. Language editing

Authors whose first language is not English are encouraged to have their manuscripts reviewed by a native English speaker or a professional editing service before submission, e.g. It is important for all submissions to be clear and coherent for the editors and reviewers.


The IJGO will consider appeals of rejected manuscripts only if factual errors are believed to have been made during the review process. Appeals can be directed to the Editorial Office at


If your paper is accepted for publication, you will receive an email informing you of this decision. All papers accepted by the journal are published on the understanding that they have not been, and will not be, published elsewhere without prior approval from Wiley.

8.3. Proofs

Once the paper has been typeset, the corresponding author will receive an email alert containing instructions about how to access the proof online. A working email address must therefore be provided for the corresponding author. The proof can be downloaded as a PDF (portable document format) file from this link. Corrections to the proof should be annotated on the PDF. Further instructions on proofing and returning corrections will be provided in the proof notification email.

NOTE: You will only be able to annotate the file using Acrobat Reader 9.0 or later. The latest version can be downloaded free of charge here:

Corrections must be returned to the publisher within 48 hours of receipt. The author is responsible for detecting typesetting errors; no major changes in–or additions to–the edited manuscript will be allowed at this stage.

The IJGO has no page charges.

8.4. Accepted Articles

'Accepted Articles' have been accepted for publication and undergone full peer review and copyediting, but have not been through the typesetting, pagination and proofreading process. Accepted Articles are published online a few days after final acceptance, appear in PDF format only (without the accompanying full-text HTML) and are given a Digital Object Identifier (DOI), which allows them to be cited and tracked. The DOI remains unique to a given article in perpetuity. More information about DOIs can be found online at Given that Accepted Articles are not considered to be final, please note that changes will be made to an article after Accepted Article online publication, which may lead to differences between this version and the Version of Record. The Accepted Articles service has been designed to ensure the earliest possible circulation of research papers after acceptance.

Accepted articles will be indexed by PubMed; therefore, the submitting author must carefully check the names and affiliations of all authors provided in the cover page of the manuscript, as it will not be possible to alter these once a paper is made available online in Accepted Article format. Subsequently, the final proofed articles will appear either as Early View articles in a matter of weeks or in an issue on Wiley Online Library; the link to the article in PubMed will automatically be updated.

8.5. 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. 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. The nature of Early View articles means that they do not yet have volume, issue or page numbers, so Early View articles cannot be cited in the traditional way. They are therefore given a DOI, which allows the article to be cited and tracked before it is allocated to an issue. After print publication, the DOI remains valid and can be used to cite and access the article.


Free access to the final PDF offprint of your article will be available via Wiley’s 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.

Should you wish to purchase additional copies of your article, please visit and follow the instructions provided. If you have queries about offprints please email:


Please note that unless specifically requested, Wiley will dispose of all hardcopy or electronic material submitted 2 months after publication. If you require the return of any material submitted, please inform the editorial office.
