Gynecology is the specialized field of medicine dealing with the health of a woman's genital system. The genital system consists of the reproductive organs, including the uterus (the womb; the organ in which a fetus develops), cervix (the opening between the uterus and the vagina), ovaries (organs that produce eggs and sex hormones), fallopian tubes (organs that carry eggs from the ovaries to the uterus), vagina (the muscular tube that extends from the uterus to outside the body), as well as their supporting structures.
