The Revista Peruana de Ginecologia y Obstetricia (The Peruvian Journal of Gynecology and Obstetrics) is the official publication of the Peruvian Society of Obstetrics and Gynecology. Its aim is to disseminate knowledge of the specialty of OB/GYN and human reproduction among partners, professional employees in the area of sexual and reproductive health and related specialties.

The Revista Peruana de Ginecologia y Obstetricia (RPGO) was founded in 1955 and since then publishes the results of original research in the field of OB/GYN and subspecialties such as: maternalfetal medicine, reproductive endocrinology and infertility, gynecologic oncology, urogynecology, laparoscopic surgery, family planning, obstetrics, pediatric and adolescent gynecology, menopausal and geriatric gynecology. In addition, issues related to gender and violence, teaching and research, and public health are published. Unpublished items of interest for the Revista Peruana de Ginecologia y Obstetricia may pertain to basic sciences, controlled clinical trials on therapeutic agents, effectiveness of diagnostic tests, epidemiological aspects, public health, and continuing medical education related to the field of the OB/GYN. The RPGO has an editorial committee designated by the Peruvian Society of Gynecology and Obstetrics, chaired by the journal’s Director; additionally, the mission, vision, objectives and functions of the editorial board are established in its internal regulations.

The Peruvian Journal of Gynecology and Obstetrics is published quarterly in four issues that comprise one volume per year. Our journal is peer-reviewed and indexed in the following databases: LIPECS, LATINDEX, IMBIOMED, REDALYC, DOAJ, HINARI, REDIB, SciELO and DIALNET. These databases periodically provide statistical information about the reading and impact of the articles published in the RPGO. Also, the RPGO is entirely financed by the Peruvian Society of Gynecology and Obstetrics, implying no cost for the authors who wish to publish nor charge for the processing of articles. Its print version is distributed among its associated members and academic institutions, with a print run of 1000 copies per issue, with free access to full text of the digital version through the Open Journal Systems platform: revista/index.php/RPGO/index. Articles published in The Peruvian Journal of Gynecology and Obstetrics are distributed into the following sections: Editorial, original articles, short communications, clinical cases, systematic reviews, symposia, controversies in obstetrics and gynecology, recent research in obstetrics and gynecology, adverse events in gynecology and obstetrics, opinion articles, special articles, historical articles, biographical sketch and letters to the Editor. It is not required to be a member of the Peruvian Society of Obstetrics and Gynecology, or to be a specialist in GYN/OB to submit articles. However, the main author must be a registered physician. The Revista Peruana de Ginecologia y Obstetricia is published according to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, last version updated in December 2018: annotated_dec18.pdf


submission of articles to the RPGO

Articles submitted to the RPGO must be unpublished. This means that neither the entire article nor parts of it have been published, nor are in the process of being published in another journal or any other form of scientific communication. The article cannot be simultaneously submitted for publication in another journal.

Articles submitted to the RPGO can be written in Spanish, English or Portuguese, according to the origin and preference of the authors. The Editorial Board may suggest authors who originally present their article in Spanish or Portuguese to translate it personally into English. This translation will be provided by the author.

The submission of papers will be exclusively in electronic format, to the following electronic addresses:

The following three files must be attached:

  1. The article prepared and written following the requirements of the RPGO:

  2. Statement of authorship and permission for publication of the scientific article with the respective signature of all authors recording their institutional affiliation, profession and highest academic degree, e-mail, telephone and the specific contribution to the development of the article. The electronic format for this affidavit is available at:

  3. Checklist, available at:

The RPGO policies, including those related to conflict of interest, ethical aspects and misrepresentation of data and documents, apply to all submitted articles. The documentation is required to start the publishing process; otherwise, the article will be returned to the author.

If the article was previously submitted to another journal, the authors must provide a detailed copy of the comments of the peer-review.

Initially, the submitted articles are evaluated by the Editorial Committee of the RPGO.

Some articles will be rejected immediately if they do not meet the stipulated requirements; all articles are subject to review by peers.


The Revista Peruana de Ginecología y Obstetricia follows the standards described in the ethical behavior and publication malpractice statement, published in the Best Practice Guidelines by the Committee on Publication Ethics COPE (

Academic ethics are a fundamental axis in research and publication, and form the basis for the reputation of scientists and physicians. In order to promote academic integrity and the publication of high quality scientific papers, the RPGO issues the following Ethics and Publication Malpractice Statement. This addresses the ethical behavior of all parts related to publishing at the journal of the Peruvian Society of Obstetrics and Gynecology (Sociedad Peruana de Obstetricia y Ginecología SPOG), including the author, the reviewer and the editor of the RPGO. The RPGO will be careful that commercial needs do not compromise intellectual and ethical standards, and will be always willing to publish corrections, clarifications, retractions and apologies when necessary.

1. Pubilcation and authorship

Authorship must be based solely on: a) substantial contributions to the conception or design of the study; or the acquisition, analysis or interpretation of the information; b) the drafting of the paper or the critical review of its intellectual content; c) the approval of the final version to be published; and d) the agreement to be responsible for the article on every aspect, ensuring that all matters related to the accuracy or integrity of any part of the work have been adequately investigated and solved: (

An author must be capable of identifying the coauthors to be responsible for specific parts of the article and must trust each of their contributions.

The corresponding author is the person who assumes the responsibility of pertinently communicating with the RPGO, during the presentation of the manuscript, the peer-review and the publication process. Those who contribute to less than 4 of the criteria mentioned above must not be listed as authors, but must be mentioned in the acknowledgments.

2. Author’s responsibilities

All authors significantly contribute to research and must send a statement that all data presented in the article are real and authentic.

Authors are required to participate in the peerreview process and must provide retractions and correct mistakes.

Before presenting articles to the journal, we encourage authors to review the suggestions by the Committee on Publication Ethics, compiled in the Code of Conduct and Best Practice Guidelines for Journal Editors ( These recommendations are endorsed by the Editorial Board of the RPGO. In accordance with these guidelines, the RPGO considers the following as ethical misconduct: plagiarism, fictitious authorship, changes in authorship, redundant publication, data manipulation, and non-revealed conflict of interest.

A. Conflict of interest

Objectivity and transparency are essential in scientific research and the review process. Researchers and authors, as well as editors and reviewers, must always declare conflicts of interest when publishing a document.

The most evident conflicts of interest are financial relations, such as:

  • Direct relations: employment, shareholding, subventions, patents.

  • Indirect relations: remunerations, consulting services to sponsoring organizations, mutual investment funds, indemnities for expert opinion.

Readers must be informed about who have financed the research and the role of the investigation’s funders. Conflicts may also arise as result of personal relationships, academic competition and intellectual appetence. The best course of action is always that of total transparency and, when in doubt, to reveal the problem. Enumerating the funding sources does not imply a conflict of interest.

B. Protection of individual information

The RPGO protects the confidentiality of individual information (e.g. that obtained by means of the doctor – patient relationship). The names of patients, initials, medical record numbers or general information that may allow identifying studied subjects must not be mentioned. Images of patients used in the publication of original articles of case reports must have a written authorization and informed consent. All recognizable traits of identifiable persons will be covered in the photographs. It is possible to publish without explicit consent if the report is important to public health.

Studies of patients, or studies of registries of patients or volunteers, require approval by the Committee of Institutional Ethics, as well as informed consent. If the study addresses topics in occupational or environmental medicine, besides ethical considerations and protecting individual information, we also require the approval for dissemination by the company where the research was performed.

C. Experimentation in humans and animals

Articles describing experiments carried out in humans must indicate whether the performed procedures followed the ethical rules of the institutional or regional Ethics Committee and the Declaration of Helsinki: en/30publications/10policies/b3/;

In Peru, the rules to follow for experimentation on humans are established in the Clinical Trials Regulation. The National Institute of Health of Peru is the authority responsible at the national level for ensuring compliance with that regulation and the related rules governing the authorization, implementation and registration of clinical trials in the Peruvian Registry of Clinical Trials: In our country, the authors of clinical trials in humans require approval by the National Institute of Health before starting the experiment. At the request of the RPGO, the author must deliver copies of documentation evidencing authorization.

For animal experimentation, the authors will take into consideration international standards, in particular those recommended by the Office of Animal Care and Use of the National Institutes of Health (, as well as the guidelines of the institution or national law governing the care and use of laboratory animals. The animals used must be named in the title, abstract, keywords and materials and methods. Such experimentation should be thoroughly detailed in the materials and methods section. Experimental research on animals performed in Peru must have the approval of the Committee of Ethics and Animal Welfare at the Faculty of Veterinary Medicine of the Universidad Nacional Mayor de San Marcos (

3. Peer review and responsiBilities of the reviewers

Review by peers or arbitration is a method used to ensure the quality, originality, feasibility and scientific rigor of a research paper. Peer review is a process that is mandatory for all types of articles which are presented to the RPGO, except for editorials, special articles, symposia proceedings, articles addressing controversies and letters to the Editor, which are evaluated by the Editorial Committee. Papers submitted to the RPGO are evaluated by reviewers with experience and knowledge in the subject referred to in the article they assess. The aim of the peer review process is that the paper’s concepts are clearly presented and achieve a high quality in order to be published. Generally, reviewers are external to the Peruvian Society of Gynecology and Obstetrics and the RPGO.

The requirements to be a reviewer in the RPGO are: knowledge of the topic, impartiality, academic rigor, research experience, innovation, responsibility and ethical conduct. The reviewer’s opinions will be objective, without any conflicts of interest concerning the research, authors or research funders. Should the contrary happen, they will not accept to undertake the peer review process. Reviewers will work with confidentiality. They must highlight relevant published papers that have not been cited in the reviewed article.

Reviewers selected for the RPGO are not remunerated, but they are mentioned in the printed volume where they contributed. When required by the article, there are reviewers with expertise in the field of biostatistics and epidemiology. The authors of articles should not suggest reviewers, since this constitutes a conflict of interest.

Papers submitted to the RPGO will be initially evaluated by the Editorial Committee to ensure they follow the established requirements. Afterwards, they will be subject to peer review. For this, the Editorial Committee will invite 2 or more reviewers per article who will anonymously qualify the article in a period of 15 days through an evaluation form provided by the journal. The content of these evaluation forms is available in the following URL as information for authors and readers: The review process is double blind. Referees or reviewers issue suggestions and recommendations on how to improve the article. The Editorial Committee and the reviewers for methodology may require that the authors send the database described in the methods and employed to obtain the results presented in the article.

The evaluation of referees considers the article:

  • Suitable for publication without changes

  • Suitable for publication with minor changes

  • Suitable for publication with major changes

  • Not suitable for publication.

The received suggestions and recommendations are sent to the author, who is given 15 days to submit the modified article. No article will be definitively accepted until all of the corrections have been clarified and modified. In this first stage, if the author doesn’t send the modified paper within the given timeframe, he or she will be notified for immediate submission; after the deadline, the article will be considered for the next issue of the RPGO.

To ease the task of the Editorial Committee, when the authors send a manuscript previously evaluated, they must enclose a letter enumerating the new modifications (section, page, line) and, when necessary, diverging points of view. Depending on the case, the RPGO can resubmit the corrected article to a reviewer before considering its publication. Should there exist any controversy or tie in the evaluation by external reviewers or by the members of the Editorial Committee, the journal’s Director is responsible for the final decision regarding the paper’s publication. If the corrections were not sent within a period of up to six months, the article will be rejected for publication, and the manuscript’s file will be eliminated.

The RPGO reserves the right to make changes or amendments to the article for the sake of a better understanding. These changes will not modify the article’s content. The corresponding author will approve the pdf file before final publication. Reviewers may suggest for the original article to be published as a short communication or as a letter to the editor.

The average time of the editorial process from reception of the item to the final decision of the Editorial Committee to publish it, including the peer review process and corrections, varies between 2 and 4 months. The author may request information on the progress of the review of the article as well as the stage of the publishing process in which the article is.

In order to promote open access, the dissemination of scientific research, and the contribution of readers, the Editorial Committee will consider publishing articles in electronic format before the respective peer review (Preprint). Also, the Editorial Committee will consider publishing in electronic format items that have been peer-reviewed and are suitable for publication prior to the quarterly deadlines of regular publication of the RPGO (advance publication).

4. Editorial responsiBility

According to the recommendations issued by the Committee on Publication Ethics COPE (, the RPGO has the commitment to satisfy the needs of both readers and authors, to constantly improve the journal, to ensure the quality of the published content, to defend freedom of expression, to maintain the integrity of academic records, to prevent commercial needs from compromising intellectual standards and, as expressed at the beginning, to be always willing to publish corrections, clarifications, retractions and apologies when necessary.

5. Statement on publication ethics

The editor’s decision to accept or refuse to publish an article will be based solely on the importance, originality and clarity of the paper, as well as on the relevance of the study. The RPGO is committed to act free of discrimination based on authors’ gender, sexual orientation, religious or political beliefs, ethnic or geographic origin.

We adopt and follow reasonable proceedings to handle complaints of conflict or of ethical nature, according to societal policies and methods, as the case may require. We will give the authors the pertinent opportunity to answer to the claim. The Sociedad Peruana de Obstetricia y Ginecología guarantees that the RPGO subscribes to the aforementioned principles.

The editor will not revoke his decisions to accept the presentation of articles unless serious problems in said presentation are identified. The new editors must not override the decisions to publish presentations made by the previous editor, unless grave issues are found.

Misconduct and ethical misbehavior can be identified and mentioned to the editor and the Sociedad Peruana de Obstetricia y Ginecología at any time, by any person, as long as enough information and evidence are provided in order to begin an investigation.

Intentional distortion or negligence in the research publication process that may lead to the fabrication of data, text, hypotheses or methods in the manuscript, or the publication of another researcher’s work, or the distortion of the research process in other ways, all represent scientific misbehavior. The RPGO will not accept plagiarism or fraudulent information.

In case any misconduct in publication ethics were detected, the RPGO will reject the article and will follow the steps recommended by the Committee on Publication Ethics, which include to inform the author’s misconduct to the other authors, to the institution he/she belongs to, to his superiors, to the research funders, to his institution’s ethics committee, and to other scientific journals. Besides, in the case of Peruvian researchers, ethical misconduct will be informed to Concytec for the corresponding sanctions, according to their faculties stated by the law: The RPGO will use computer software to detect misconduct in publication ethics.


We recommend authors submitting articles to the RPGO to follow the internationally established standards for design, development and presentation of different types of studies:

  • Randomized controlled trial: CONSORT(

  • Systematic review and meta-analysis: PRISMA (

  • Systematic review and meta-analysis of observational studies: MOOSE (http://www.consort-statement. org/esources/downloads/other-instruments)
