What is the step of fertilization? The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
What are the 5 stages of Fertilisation? During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote.
