an ovum mature oocyte after meiosis division
At fertilization the secondary oocyte completes its second meiotic division
Oviduct
The Graffian Follicle in the ovary expels the secondary oocyte (mature ovum) into the peritoneum, where it is picked up by the fimbrae of the Fallopian tubes.

Human oocytes mature immediately after the surge of LH which occurs at ovulation. The surge of LH causes maturation of the oocyte which is the completion of the first division of meiosis.

Follicle development occurs in several stages: primordial follicle, primary follicle, secondary follicle, preantral follicle, antral follicle, and mature (Graafian) follicle. Each stage involves specific changes in the follicle and oocyte as they mature towards ovulation.
Seeing as 1 primary oocyte produces 1 ovum and 3 polar bodies 50 oogonia give 50 ovums Seeing as 1 primary oocyte produces 1 ovum and 3 polar bodies 50 oogonia give 50 ovums
ovum is the product after the secondary oocyte fuses with sperm
