Use when targeting the American Journal of Obstetrics and Gynecology or deciding whether an obstetrics or gynecology clinical study fits this venue. Encodes the journal's fit across maternal-fetal, reproductive, and gynecologic research, the clinical-evidence and pregnancy-ethics bar, reporting-guideline and registration requirements, AJOG house style, official-submission re-check, and desk-reject heuristics. Venue-fit aid only, not clinical advice.
