Female reproductive organs, endoscope view. One of the two ovaries (white) has been lifted into view by a tool (black). Below the ovary is the opening of its fallopian tube. The rest of the tube is at left of the tool, running up towards the uterus (round organ, above ovary). Between the tool and the fallopian tube is the ligament that connects the ovary to the uterus. Other abdominal organs make up the rest of the image. Ovaries contain maturing female reproductive cells (ova, eggs). An egg is released during ovulation, and it passes through its fallopian tube to reach the uterus. If the egg is fertilised and implants in the uterus wall, it can develop into a baby. Most ovaries are 2-4 centimetres long.
