Obstetrics and gynaecology (or obstetrics and gynecology; often abbreviated to OB/GYN, OBG, O&G or Obs & Gynae) are the two surgical–medical specialties dealing with the female reproductive organs in their pregnant and non-pregnant state, respectively, and as such are often combined to form a single medical specialty and postgraduate training programme. This combined training prepares the practising OB/GYN to be adept at the surgical management of the entire scope of clinical pathology involving female reproductive organs, and to provide care for both pregnantand non-pregnant patients. In veterinary medicine, theriogenology is more commonly used term that also includes andrology.
