Ovulation and fertilisation. Computer artwork of the female reproductive system, showing the development of an ovum (egg, small circle) inside an ovary (oval, centre left) and its subsequent fertilisation. The Graafian follicle (blue, inside ovary) releases its egg at ovulation. The follicle then develops into a corpus luteum (yellow), which secretes progesterone to build up the lining (beige) of the uterus (womb, right), ready for a fertilised egg. The ovum passes through the oviduct (far left) into the fallopian tube (upper left), where it is fertilised by a sperm (black, upper left). It then starts dividing into a cluster of cells (blastocyst, blue), which passes along the fallopian tube to the uterus, where it implants in the uterine lining and.
