The **American College of Obstetricians and Gynecologists (ACOG)** is a leading professional organization for physicians specializing in obstetrics and gynecology in the United States, with over 62,000 members including medical students, residents, practicing and retired physicians, and allied health professionals[1][4]. Founded in 1951 in Chicago, ACOG has become the premier voice for women’s health care providers, promoting the highest standards of clinical practice, education, and advocacy for reproductive health[1][2][4].
ACOG operates as a nonprofit 501(c)(6) organization, with a companion 501(c)(3) entity focused on education and limited political activity. Together, they support members through evidence-based clinical guidelines, continuing education, management tools, and career resources[1][4]. The organization’s members, called fellows (FACOG), must be certified by the American Board of Obstetrics and Gynecology and nominated by peers[1].
Historically, ACOG has played a pivotal role in advancing women’s reproductive rights, notably challenging an anti-abortion law before the U.S. Supreme Court in *Thornburgh v. American College of Obstetricians and Gynecologists* (1986), and affirming support for safe abortion access post-Roe v. Wade[1][3]. It balances physician autonomy with patient-centered care, emphasizing science-backed, respectful treatment.
ACOG’s initiatives extend beyond clinical care to public health programs such as adolescent health, fetal and infant mortality review, violence prevention, and contraception access. Its patient education platform, Every Stage Health, empowers women with reliable information[2][4][5]. The organization also addresses emerging issues like immunization, infectious diseases, and abortion care through programs like IMPACT and maintains a respected publication, *Obstetrics & Gynecology* ("The Green Journal")[1][5].
Today, ACOG remains a powerful advocate for equitable, quality women’s health car
