The female reproductive system consists of two
ovaries, two fallopian tubes, the uterus, and the vagina. Either the left or
right ovary normally produces an egg (ovulation) about 11 to 17 days before the
woman's next menstrual period, or approximately once a month. The egg is
released from the ovary into a fallopian tube and swept into the uterus by tiny
hairlike cells (cilia) and muscle action.
