The female reproductive system contains two main parts: the uterus, which hosts the developing fetus, produces vaginal and uterine secretions, and passes the anatomically male sperm through to the fallopian tubes; and the ovaries, which produce the anatomically female egg cells.
Some common, normal signs include irregular periods, hot flashes, vaginal dryness, sleep disturbances, and mood swings—all results of unevenly changing levels of ovarian hormones (estrogen) in your body.
