Obstetrician / Gynecologist Overview. An obstetrician is a physician who has successfully completed specialized education and training in the management of pregnancy, labor, and pueperium (the time-period directly following childbirth).
Obstetrics and gynecology is the medical specialty that deals with obstetrics and gynecology. Postgraduate training programs for both aspects are usually combined, preparing the practicing obstetrician-gynecologist to be adept at the care of female reproductive organs' health and at the management of pregnancy, although many doctors go on to develop subspecialty interests in one field or the other.
