Childbirth and obstetrics in Classical Antiquity (here meaning the ancient Greco-Roman world) were studied by the physicians of ancient Greece and Rome. Their ideas and practices during this time endured in Western medicine for centuries and many themes are seen in modern women's health. Gynecology and obstetrics were originally studied and taught mainly by midwives in the ancient world, but eventually scholarly physicians of both sexes became involved as well. Obstetrics is traditionally defined as the surgical specialty dealing with the care of a woman and her offspring during pregnancy, childbirth and the puerperium (recovery). Gynecology involves the medical practices dealing with the health of women's reproductive organs (vagina, uterus, ovaries) and their breasts.
