Female reproductive system Female reproductive system. The female reproductive system (or female genital system) is made up of the internal and external sex organs that function in human reproduction. The female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and to carry a fetus to full term. The internal sex organs are the uterus and Fallopian tubes, and the ovaries.

Female Reproductive System Female reproductive organs. The female reproductive system is more complex than that of the male. It produces ova (egg cells); nourishes, carries, and protects the developing embryo; and nurses the newborn after birth. The system structures are the ovary, uterine tubes, uterus, vagina, vulva, and mammary glands.

The Reproductive System Separate pages describe the male reproductive system and the female reproductive system. 1  The reproductive systems of both sexes share the same basic organization: The gonads produce gametes (eggs or sperm) which unite during fertilization. 2  The creation of gametes is called gametogenesis. The process follows the same general sequence in both males and females: Gamete production begins with germ cells, which begin to develop and multiply in the embryo. They are diploid cells, containing 23 pairs of chromosomes for a total of 46 chromosomes.

Uterus and Ovaries Uterus and Ovaries. The uterus and ovaries are the most vital organs of the female reproductive system. These organs work together to produce female sex hormones, produce and develop ova (egg cells), and support the development of a fetus during pregnancy.
