Difference Between Egg and Sperm Cell Formation
Embryology - The human egg cell and sperm
For a conception an egg cell and many sperm are needed. When the cells find each other, they fuse after a while and the chromosomes come together. Phenomenology gives us the characteristics of the ovum and sperm. There are no cells in humans that are so different and yet belong so much together. The egg cell or ovum, or oocyte is the largest human cell.

Fertilization and development review
Fertilization occurs when a sperm and an oocyte egg combine and their nuclei fuse. 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. This new single cell, called a zygote , contains all of the genetic material needed to form a human—half from the mother and half from the father.
Human fertilization is the union of a human egg and sperm , usually occurring in the ampulla of the fallopian tube. Scientists discovered the dynamics of human fertilization in the nineteenth century. The process of fertilization involves a sperm fusing with an ovum.
