The Sperm and the Egg 2 The Sperm and the Egg The egg, known as the ova is already present in the female body at birth. Women do not produce any ova, but are usually born with a reserve of about 400,000 eggs. The eggs are located within the ovary, “within a thin capsule, or follicle” (Rathus, Nevid, Fichner-Rathus, 2005, p. 75). Meanwhile in the male body, sperm is located within somniferous tubules in the testicles, which uses spermatogenesis to produce billions of sperm a year. Fertilization occurs when random mature sperm cells called spermatozoa comes “into contact with follicle cells adhering to the secondary oocyte, which still lies high in the uterine tube” (Human Embryology, 2009). After a successful maneuver, one sperm cell (known as Mr. Victorious), reaches the cytoplasm and the cell membrane of the oocyte and continues the journey forward after emitting a special substance into the oocyte to knock out the competing sperm cells. The oocyte then absorbs the Mr. Victorious. Mr. Victorious then travels to the middle of the cytoplasm, where his tail disconnects from his head to form the pronucleus. Following the separation of the second polar body, the oocyte nucleus reconstitutes typically and is then called the female pronucleus of the ripe egg (Human Embryology, 2009). The female pronucleus (known as Mrs. Rosebud) is now ready to begin the final stages of fertilization with Mr. Victorious. The meiosis and the mitosis process begin, in which Mr.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
