At the end of the female fallopian tubes, between a sperm cell and an egg cell (ovum). Fertilization, pictured in Figure 1a is the process in which gametes (an egg and sperm) fuse to form a zygote. Because each of these reproductive cells is a haploid cell containing half of the genetic material needed to form a human being, their combination forms a diploid cell.

The zygote formed after fertilization divides repeatedly to form a mass of cells known as the embryo. The most primitive form of fertilization, found in microorganisms and protozoans, consists of an exchange of genetic material between two cells. The fertilized egg then moves to the uterus, where it implants to the uterine lining. Up to 150 million sperm can be released in just one ejaculation of the man's semen. This fertilized egg is called an embryo or a zygote. Human fertilization occurs when a sperm cell successfully joins with an egg cell, fertilizing the egg which then becomes known as a zygote.

The process of fertilization involves a sperm fusing with an ovum. While many think fertilization occurs in the ovary, it actually takes place in the fallopian tube just outside the ovary. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm. If fertilization does not occur, the ovum disintegrates and is destroyed by the tube. It occurs in one of the fallopian tubes. Does fertilization occur in the oviduct?
