Gynecology and obstetrics are the studies of the female reproductive system. Obstetrics is the branch of medicine that focuses on women during pregnancy, childbirth, and the postpartum period. Gynecology is a broader field, focusing on the general health care of women and treating conditions that affect the female reproductive organs. Doctors who are specialized in gynecology and obstetrics will have to undergo four years of post-medical school training in the areas of women’s general health, pregnancy, labor and delivery, preconception and postpartum care, prenatal testing, and genetics. For example, women may be referred as gynecologists in the earlier stages of pregnancy, and obstetricians later in their term.
