The Indonesian Journal of Obstetrics and Gynecology (INAJOG) welcomes submissions from researchers and practitioners in the field of obstetrics and gynecology. Manuscripts may be submitted as research articles or case reports. All manuscripts must be original, not previously published or under consideration elsewhere, written in English, and should not exceed 5,000 words or 10 pages in length.

The title of the manuscript should be brief, specific, and informative, accompanied by a short running title of no more than fifteen words. Authors are required to provide their full names, the corresponding author’s address for proofs, and the name and address of the department or institution to which the work should be attributed.

An abstract of no more than 250 words must be included, summarizing the background, objectives, methods, results, and conclusions of the study. Three to five keywords should be listed below the abstract. The introduction should present the background of the problem, the formulation of the research question, and the objectives of the study.

The methods section must clearly describe the materials and procedures used, with sufficient detail to allow replication. Established methods should be referenced, while new or modified methods must be explained thoroughly. Results should be presented in logical sequence, supported by tables and figures only when necessary to highlight key findings. Decimal numbers must use a point (.) as separator. Tables, figures, and photographs should be cited consecutively in the text. Non-standard abbreviations must be defined at their first mention in the text. Mathematical equations should be clearly stated.

The discussion should interpret the results, explain their significance, and compare them with previous studies. Authors should highlight how their findings contribute to solving the research problem, note any limitations, and suggest possibilities for future research. This section should conclude with a clear statement of the study’s overall findings. The conclusion itself must provide concise answers to the research question in clear and descriptive sentences.

References must follow the Vancouver style and be managed using applications such as Mendeley or EndNote. Authors are required to include at least two citations from INAJOG. References must be cited in the text using superscript Arabic numerals, numbered consecutively in order of appearance, and listed at the end of the manuscript in numeric sequence.

For research articles, the manuscript should be organized into the following sections: title, author information, abstract, objective, methods, results ending with a conclusion, and references. Case reports or case series should be structured into title, author information, abstract, introduction, case description and case management (supported by photographs or illustrations), discussion ending with a conclusion, and references.

Each article may contain a maximum of three tables and three figures or graphs. Photographs, whether in color or black and white, must be clear and of high quality. Manuscripts must be submitted through the INAJOG website (inajog.com), typed with 1.5 line spacing on A4 paper, in single-column format, with margins of 2.5 cm (1 inch) on all sides.
