ovulation

the discharge of the ovum from the graafian follicle.

The discharged ovum enters the uterine tube adjoining the ovary and moves toward the uterus; if it encounters a spermatozoon while it is still alive (about 48 hours), the two merge. Fertilization usually takes place in the uterine tube. The fertilized ovum then makes its way to the uterus, where it becomes embedded in the prepared wall as the first stage of growth of the embryo. See also estrus, estrous cycle.
