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.
Papers are seen by editors prior to being sent to full peer review, and those that are not in the remit of the journal or that do not meet the standards of science required may be rejected without full review.
The journal aims to return a decision on a peer-reviewed paper in less than a month.
- Approval – Ensure all authors have seen and approved the final version of the article prior to submission and are aware it is being submitted to Reproduction and Fertility.
- Open access – The appropriate open-access option must be selected on submission. Authors are responsible for ensuring any funder mandates are followed. For further details, please see the open access policy.
- Charges – Reproduction and Fertility is an open-access journal, and an article publication charge is payable upon acceptance. Full details are available on the publication charges page.
- Ethical compliance – All articles are required to meet the requirements outlined in our ethical policy. Ensure you have included all relevant ethical approval statements.
- Reported data – Data accuracy is crucial. Authors are strongly encouraged to double-check all reported data for accuracy and to confirm that all units of measurement are correct and consistent.
- Author list – All authors must be listed on the title page and entered on the ScholarOne Manuscripts submission in the correct order. Ensure all author email addresses provided are valid. Author information entered into ScholarOne Manuscripts will be used to generate PubMed listings for published papers.
- Cover letter – This letter should introduce your paper and outline why your work is important and suitable for publication at this time.
- English language – Non-native English speakers are encouraged to have their manuscript professionally edited before submission. See Bioscientifica’s recommended English language editing services. Manuscripts may be written in either UK or US English.
Reproduction and Fertility offers a flexible submission process for first time submissions wherein authors can submit in any recognisable manuscript format, but should be complete such that editors and peer reviewers may easily assess the scientific merit of the study.
Revisions, where invited, should follow the standard Reproduction and Fertility formatting outlined below, using the highlighter function to indicate changes, and should be accompanied by a full response letter to editor and reviewer comments.

If you would like to submit a review please email the editorial office
with a brief outline (0.5–1 page) of your topic.
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.
Research Letters are short reports of original research. Research Letters should be a maximum of 500 words, have a maximum of 1 figure or graph, 5 references, and up to 5 authors. An abstract is not required for a Research Letter, so please write 'not applicable' in the Abstract box when submitting your manuscript.
Supplementary data exceeding the bounds of the manuscript may be submitted for online publication, and 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.
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.
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.
In general, studies that are based on observations performed in a single cell line will not be considered for publication if other lines of the same general lineage and characteristics are available. If at all possible, observations should be replicated in multiple cell lines.
Authentication of cell lines
We require that all cell lines are authenticated for correct origin. Specifically, the author should include the following information supporting the authentication of lines:
- Source of cell lines. Gifts of cell lines from individuals will not be acceptable
- Please state what the method of authentication is. For example, ATCC uses STRS analysis
- State the passage number(s) of cell lines used for the experiments described in the submission. Unless the research is specifically about senescence, lines >35 passages would not be acceptable.
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, eg TGFBR2 not TGFβR2
- Avoid hyphens unless they are part of the approved symbol, eg IGF1 not IGF-1
- Please use arabic rather than roman numerals, eg BMPR2 not BMPRII
Follow species-specific formatting standards as follows:
Mice and rats
- Gene symbols should be in italics with only the first letter capitalised, eg Sox2
- Protein designations should be the same as the gene symbols except that all letters should be capitalised and in roman (ie not italicised), eg 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.
Humans, non-human primates and domestic species
- Gene symbols should be in italics with all letters capitalised, eg SOX2
- Protein designations should be the same as the gene symbols but not italicised, eg SOX2
- Please use symbols approved by the HUGO Gene Nomenclature Committee (HGNC).
- Gene symbols should be in italics with all letters in lower case, eg sox2
- Protein designations should be the same as the gene symbols but not italicised and with the first letter capitalised, eg Sox2
- Please use symbols approved by the Zebrafish Nomenclature Committee (ZNC), which can be queried at the ZFIN website.
Digital image integrity
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. 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 (eg 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 (eg 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.
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 (eg 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.
Bar charts are discouraged; scatter plots more faithfully describe the data being presented. 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.
- 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
