Female reproductive system, endoscope view. The uterus (womb) is at upper right, at centre is an ovary (white), between the uterus to the ovary is a fallopian tube. The ovaries release an egg every month (ovulation), which is received by one of the two fallopian tubes. It travels along this tube to the uterus, a pear-shaped, hollow, muscular organ, in which the egg, if fertilised, will implant and grow.
