The |female reproductive system| is responsible for generating the ovum, or egg, for storing the fertilized ovum, and nourishing the gestating |embryo| and |fetus|. The chief organs include the |ovaries|, the |uterus|, |vagina|, and the fallopian tubes. External (vulvar) organs include the |labia majora|, the labia minora, the mons |pubis|, the clitoris, the vestibule, and the greater vestibular cleft. The ovum, or egg, contains the female's contribution to the genetic make-up of the new child, and is generated in the |ovaries|. The newly generated ovum is passed through the |fimbriated extremity| of a fallopian tube, into the fallopian tube and there is fertilized by a spermatozoon (sperm cell). During sexual arousal, a fluid created by the male's |seminal vesicles| and the |prostate gland| combines with the sperm cells to create ~semen~, which is carried through the |urethra| and out of the opening, or ~meatus~, in the end of the erect penis. When the ~semen~ is deposited in the female |vagina|, the spermatozoa swims through the |uterus| to the fallopian tube, where it fertilizes the ovum, or egg. The fertilized egg travels down the fallopian tube within the next three days and becomes attached to the wall of the |uterus| (womb). There, during |pregnancy|, the fertilized egg will be nourished and will develop into the |embryo| and, later, the |fetus|. Once fully developed (after about 9 months), muscular |contractions| (labor) will push the |fetus| out of the womb.
