L'Associazione degli Ostetrici e Ginecologi Ospedalieri Italiani, AOGOI, è stata fondata a Bologna il 13 ottobre 1948. È una grande comunità scientifica, punto di riferimento fondamentale della Ginecologia Italiana, all'avanguardia nella ricerca scientifica in campo ostetrico e ginecologico.

The foundation of the SOGC in 1944 reflected the need to promote physician education, research and excellence in care – including an unmatched Continuing Medical Education program and the Journal for Obstetrics and Gynaecology. Over the past two decades, the SOGC has broadened this purpose to include international women’s health, advocacy, aboriginal health, public education, patient safety, and human resources in ob/gyn. The society has also opened its doors to other professions such as nursing and midwifery. The Society of Obstetricians and Gynaecologists of Canada is comprised of over 3,000 professional members, including gynaecologists, obstetricians, family physicians, nurses, midwives and allied health professionals.

The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) is dedicated to maintaining the highest possible standards in obstetrics and gynaecology in Australia and New Zealand.

The RCOG encourages the study and advancement of the science and practice of obstetrics and gynaecology. We do this through postgraduate medical education and training development, and the publication of clinical guidelines and reports on aspects of the specialty and service provision. The RCOG Global Health Unit works with other international organisations to help lower maternal morbidity and mortality in under-resourced countries.
