A specialist in the medical and surgical problems associated with women's reproductive system. These doctors receive at least four years of specialty training to prepare them to assist women with pregnancy, delivery, postnatal care and other women's health issues. Many OB-GYN serve as primary care physicians for their patients and are viewed as such by insurance plans. During pregnancy, a strong doctor-patient relationship often develops. This relationship can be a source of confidence and trust in dealing with other health issues. Surveys have shown that women often continue to receive care from the same OB-GYN for many years.
