Obstetrics and Gynecology
Test Questions
Course Introduction
Obstetrics and Gynecology is a medical course that focuses on the comprehensive study of the female reproductive system, including pregnancy, childbirth, and the postpartum period (obstetrics), as well as the diagnosis, treatment, and prevention of diseases affecting the female reproductive organs (gynecology). The course covers core concepts such as reproductive anatomy and physiology, prenatal care, labor and delivery management, high-risk pregnancies, contraception, infertility, menstrual disorders, and gynecological cancers. Students gain both theoretical knowledge and practical skills essential for providing care to women across all life stages, preparing them for clinical practice and further specialization within the field.
