In medicine, obstetrics is the specialty that focuses on pregnancy and childbirth. A pregnant woman usually chooses a doctor or midwife who works in obstetrics.
Doctors who care for patients before, during, and just after the birth of a baby are called obstetricians, and their field is obstetrics. Many of these doctors also practice as gynecologists — specialists in all women's medicine. The earliest definition of obstetrics is "the science of midwifery," from the Modern Latin obstetricus, "pertaining to a midwife," which has the root word obstetrix, "midwife," or literally "one who stands opposite."
