Ovulation. Image 3 of 5. Endoscope view of the rupture scar (red, lower left) formed by the release of a mature egg (ovum, female reproductive cell) from an ovary (white, centre). The egg developed from an oocyte inside an ovarian follicle that distended to form a fluid-filled Graafian follicle just prior to rupturing. The egg will not be visible on this scale. The egg will travel to the uterus (top left) along the Fallopian tube of its ovary. A successfully- fertilised egg may develop into a baby during pregnancy. For a sequence of endoscope images showing the stages of ovulation, see images P616/326-330.
