"Womens Care" most commonly refers to the physicians who specialize in gynecology, the study of the female reproductive system, and/or obstetrics, the branch of medicine that deals with childbirth and caring for women during their pregnancies. Although physicians can limit their field of study to either gynecology or obstetrics, many physicians often choose to combine these two medical fields. Many women now use these "Ob/Gyn's" as their primary care physician and are increasingly caring for all aspects of a women's overall health.
