Gynecologists specialize in the female reproductive system, but also care for women's overall health. A gynecologist is a doctor who treats medical conditions and diseases that affect women and their reproductive organs. (Gynecologists are also trained in obstetrics-the care of women during pregnancy and childbirth, which overlaps with gynecology.) 2.
OB/GYN is the abbreviation for an obstetrician-gynecologist. An OB/GYN has many jobs. What you see an OB/GYN for depends on where you are in your life. For the majority of your life, you will need the services of a gynecologist. An obstetrician's services are only needed when you are pregnant. Some doctors are both obstetrician-gynecologists.
