ovulation [‚äv·yə′lā·shən]

(physiology)

Discharge of an ovum or ovule from the ovary.

Ovulation

the discharge of the ovum from the ovary into the body cavity. The follicle that contains the ovum ruptures during ovulation; in humans and mammals it is called the Graafian follicle. Ovulation occurs periodically in females of most vertebrates and in women. In some animals, for example, the rabbit, cat, and polecat, it is triggered by copulation. It is stimulated by gonadotrophic hormones, which are secreted by the pituitary gland and are controlled by the central nervous system. In birds the number of daylight hours is a signal for ovulation; in fish, water temperature.
