Although a CNM may hold a doctoral degree in nursing, a midwife is not a medical doctor. A CNM is an advanced practice registered nurse who completes graduate-level training through programs accredited by the ACME. In contrast, a physician practicing within the specialties of obstetrics, gynecology, or both (OB-GYN) has met the requirements to practice medicine in these specialties—which includes undergraduate education, a degree from a medical school, medical licensure, and 3 to 7 years in internship and residency programs. However, both CNMs and OB-GYN physicians provide comprehensive medical care throughout a woman’s lifespan—including pregnancy and childbirth. They diagnose, treat, and help prevent diseases women may experience, especially those affecting the reproductive system.
