The uterus is an organ in the female body where the fetus is gestated to maturity. It is directly connected to the vagina through the cervix. The fallopian tubes connect the uterus to the ovaries. In fertile women, the uterus readies itself for the implantation of a fertilized ovum about once every month. If the ovum is not fertilized, the cells of the uterus are shed in menstruation.
