The American College of Obstetricians and Gynecologists (ACOG) is the definitive professional body for obstetrician-gynecologists in the United States. Founded in 1951 and headquartered in Washington, DC, it represents more than 60,000 members and sets much of the clinical standard of care in US women's health through its Practice Bulletins, Committee Opinions and Clinical Practice Guidelines.

As a publisher, ACOG is deliberately small. It owns two journals - the monthly Obstetrics & Gynecology, published since 1953 and known everywhere as the Green Journal, and O&G Open, a fully open-access companion launched in 2024. Both are produced for ACOG by Wolters Kluwer under the Lippincott Williams & Wilkins imprint, which handles production, hosting on journals.lww.com, and open-access billing. If you are writing clinical obstetrics or gynecology research for a US practitioner audience, these are the society's two venues.

Because the portfolio is only two titles, the choice is mostly about open-access requirements and selectivity rather than subject fit.

• Obstetrics & Gynecology (the Green Journal) - monthly, published since 1953, ISSN 0029-7844. Original clinical research, systematic reviews, clinical expert series, case reports and editorials in obstetrics, gynecology, maternal-fetal medicine, gynecologic oncology, reproductive endocrinology and urogynecology. It is also the journal of record for ACOG's own clinical documents: Practice Bulletins, Committee Opinions and Clinical Practice Guidelines are published here, which is a large part of why the title is so widely read and cited.
• O&G Open - online-only, fully open access, launched in 2024 with Wolters Kluwer. Peer-reviewed original research, reviews, clinical perspectives and consensus statements across obstetrics, gynecology and closely related fields.

ACOG also publishes patient education materials, practice-management resources and educational content, but those are not peer-reviewed journal venues and are not covered by this guide.

ACOG offers three routes. Fees are revised periodically, so confirm the current figure on the journal's author page before you submit.

Open-access charges are invoiced after acceptance: the corresponding author receives a publication-charge letter from Copyright Clearance Center with payment instructions. Discounts and hardship waivers are handled case-by-case through Wolters Kluwer rather than by a published tiered policy, so ask the editorial office early if cost is a barrier.

• Model: single-anonymized peer review - reviewers see author identities, authors do not see reviewers.
• Triage: the Green Journal's acceptance rate is low, and a substantial share of submissions are declined by the editors without external review. A fast rejection is common and is not a reflection on methodology.
• Statistical review: clinical research with quantitative outcomes is routinely sent for dedicated statistical review, so pre-register where applicable and report your analysis plan clearly.
• Reporting guidelines: CONSORT, STROBE, PRISMA and similar checklists are expected for the corresponding study types. Trials must be prospectively registered.
• Turnaround: first decisions typically arrive within a few weeks; triaged papers come back faster.

1. Pick the journal. Green Journal for flagship reach, O&G Open if you need immediate open access.
2. Read the Instructions for Authors. The Green Journal publishes them in the January and July issues and online; O&G Open has its own author page on journals.lww.com.
3. Format your manuscript. ACOG journals use AMA numbered citation style. Use the ACOG template on SciSpace to get the reference style, headings and structured abstract right the first time.
4. Submit through Editorial Manager. The Green Journal uses ong.editorialmanager.com; O&G Open has its own Editorial Manager site.
5. Complete the disclosures. Conflict-of-interest statements, funding sources, trial registration numbers and any required patient-consent documentation are checked at submission.

ACOG's journals follow COPE guidance on authorship, corrections and retractions, and ACOG is a COPE member. Expect strict handling of conflicts of interest - unsurprising for a title that also carries clinical guidance that shapes practice - along with ICMJE authorship criteria, mandatory prospective trial registration, and IRB or ethics-committee approval statements for human-subjects research. Data-sharing statements are encouraged; check the current author instructions for the exact requirement that applies to your article type.
