Obstetrics and gynaecology (also spelled as Obstetrics and Gynecology; abbreviated as Obs and Gynae, O&G, OB-GYN and OB/GYN) is the medical specialty that encompasses the two subspecialties of obstetrics (covering pregnancy, childbirth, and the postpartum period) and gynecology (covering the health of the female reproductive system – vagina, uterus, ovaries, and breasts). The specialization is an important part of care for Women's health.
Postgraduate training programs for both fields are usually combined, preparing the practising obstetrician-gynecologist to be adept both 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.
According to the American Board of Obstetrics and Gynecology (ABOG), which is responsible for issuing OB-GYN certifications in the United States, the first step to OB-GYN certification is completing medical school to receive an MD or DO degree. From there doctors must complete a four-year OB-GYN residency program approved by the Accreditation Council for Graduate Medical Education (ACGME). For the 2021 Electronic Residency Application Service (ERAS) match, there were 277 OB-GYN residency programs accepting applicants.
In their fourth year of residency, with an affidavit from their director to confirm program completion, OB-GYN residents can choose whether to begin the board certification process by applying to take the ABOG Qualifying Exam, which is a written test. If residents pass the Qualifying Exam, demonstrating they possess the knowledge and skills to potentially become certified OB-GYNs, they are then eligible to sit for the oral Certification Exam. Prior to the Certification Exam, residents must also gather a list of patient cases they've worked on throughout their residency in order to demonstrate their competence and experience in OB-GYN patient care.
Residents then sit for the three-hour oral exam at ABOG's test center, and if they pass the exam they become "board certified" OB-GYNs.
