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 hairs (cilia) and muscle action.
