  1. JBRA Assisted Reproduction (JBRA Assist Reprod) is the official publication by both the Brazilian Society of Assisted Reproduction (SBRA –, the Latin America Network of Assisted Reproduction ( and Pronúcleo - Brazilian Association of Embryologists destined to scientific-based and quarterly issued papers. It is designated to specialists and researchers in the health area, in particular to gynecologists, andrologists, biologists, urologists and embryologists. Basic and clinical studies in the areas of assisted reproduction, infertility, reproductive genetics, reproductive immunology, andrology, reproductive microbiology, laboratory in assisted reproduction and gynecological endocrinology will be accepted for evaluation in the form of original articles, reviews, update articles and case reports (as detailed below). Articles must be submitted in English.
  2. Papers submitted to JBRA Assisted Reproduction must be original, that is, they cannot have been either published or submitted for analysis by other journals, partially or in the whole. In cases where the illustrations have been published previously, an authorization must be granted and the source cited.

The complete version of the text is available at Manuscripts not in accordance with the instructions presented herein will be returned for modifications to be made before the Editorial Board has evaluated them.
    Authors should state that the study was approval by the Research Ethics Committee /REC from the institution where it was carried out (or from another that has a constituted and been appropriately designed), also mentioning the approval or exemption of the free informed consent by the same committee. If needed, the journal reserves the right to require the authors its sending.
    When studies in humans are being reported, authors should indicate if the study processes are in accordance with the ethics standards defined by the committee in charge for studies in humans (institutional or national, if applicable) and in accordance with the 1975 Helsinki declaration, which was reviewed in 2013. If studies are performed in animals, authors must indicate if the institutional/national guidelines for care and use of animals were followed. In any research, be it clinical or experimental.

  4. Every article published in JBRA Assisted Reproduction undergoes a review process by specialists (peer review). Submitted articles are primarily sent to editors for an initial evaluation as to the scope of the work and the editorial demands of the journal. In case of a positive evaluation, the article is then sent to two reviewers specialized in the appropriate area. Every process is anonymous, that is, reviewers are not aware of author’s identity and place of origin and vice versa. After the articles are evaluated by reviewers, they can be accepted without alterations, refused or returned to authors along with suggestions for modifications. Each article may return to its author several times for clarification and alteration, without necessarily meaning a future acceptance of the article.
  5. The co-authorship concept connotes substantial contribution in the creation and planning of the paper, analysis and interpretation of data not to mention the writing and critical revision of the text. Significant contributions given to the study which do not fit these criteria must be cited in the acknowledgements section.
  6. Clinical trials articles should be registered in the Clinical Trials Registry validated by the criteria established by the World Health Organization and by the International Committee of Medical Journal Editors (for instance,,,, and The study identification number shall be presented at the end of the abstract.

Authors should return approved papers by e-mail or fax 48 hours after receiving the message.

Original articles. Pieces of work resulting from scientific research presenting original data about experimental or observational aspects of medical, biological, biochemical and psychosocial character and including descriptive statistical analysis and/or inferences of own data. These articles have priority for publication. They must be composed of: title page, abstract and keywords, text (divided in Introduction, Material and Methods, Results, Discussion or equivalent, Conclusion), acknowledgments (if applicable), references, tables (if available), figure legends (if available) and figures (if available).
Reviews. Papers whose aim is to summarize, analyze, evaluate or synthesize investigative papers already published in scientific journals. They must include a synthesis and critical analysis of the researched literature and cannot be confused with update articles. They must be composed of: title page, abstract and keywords, text, references, tables (if available), figure legends (if available) and figures (if available).
Update or opinion articles. Papers reporting usually current information on themes of interest to certain specialties (such as a new technique or method). They have different characteristics from reviews, since they do not display critical analysis of the literature. They must be composed of: title page, abstract and keywords, text, references, tables (if available), figure legends (if available) and figures (if available).
Case reports. Articles representing descriptive data of one or more cases, exploiting a method or problem through example(s). The selected cases should be of great interest, with unusual disease or evolution or submitted to unexpected or alternative treatments. They must involve humans or animals and should present the studied individual’s characteristics (gender, age, etc.). They must be composed of: title page, abstract and keywords, text (divided in: Introduction, Case Description and Discussion or equivalent), references, figure legends (if available) and figures (if available).
Letters to the reader. Letters to the editor commenting, discussing or criticizing articles published in JBRA Assisted Reproduction will be welcome and published as long as they are accepted by the Editorial Board. They must be composed of: title, name of author, identification of the publication being commented on and references (if available).

The content of the texts should not exceed 250 words.
For original articles, the abstract should be structured as follows: Objective, Methods, Results and Conclusion. For case reports, reviews and update articles, the abstract should not be structured. The use of abbreviations should be avoided in the abstract, and references should not be cited. Right after the abstract, three to six keywords should be presented.
This part is dedicated to acknowledging the work of those who have helped intellectually, but whose contribution does not justify co-authorship or those people or institutions who  have given material support.
In the text, the citations will be identified by the author’s last name in parentheses followed by the publication year.
Examples: one author (Steptoe, 1978), two authors (Edwards & Steptoe, 1980), and more than two authors (Van Steirteghem et al., 1988).
The references should be presented in alphabetical order (each author’s surname followed by his/her first two initials), and should not be numbered. Papers by the same author should be chronologically organized; papers by the same author in the same year should be identified with letters after each year (2000a, 2000b, etc.). The presentation of references will follow the template Human Reproduction Style. We advise support Citation Style Language styles, such as Zotero, after which citations and bibliographies will be automatically formatted in this chosen Human Reproduction Style.
