Human fertilization is a complex process that involves several steps:
Ejacu**** and Ovulation: The most common sequence begins with ejaculat** during copulation, followed by ovulation.
Sperm Journey: After ejacula****, sperm begin their journey inside the female reproductive tract until they reach the Fallopian tubes, where the egg cell is located. Out of the millions of sperm released during ejacula****, just about two hundred are able to hit the egg cell in the Fallopian tube.
Penetration of the Corona Radiata: The first stage of human fertilization is the penetration of spermatozoa into the corona radiata of the egg, a coat made of cells that surrounds the egg. Sperm cells are able to go through this first barrier thanks to the release of the hyaluronidase enzyme, and the motion of their flagellum (the tail).
Penetration of the Zona Pellucida: More than a single sperm cell is required to degrade the ZP. Nonetheless, in the end, only one sperm will penetrate this layer.
Fusion of Membranes: The sperm plasma then fuses with the egg’s plasma membrane and their nuclei fuse1. This triggers the sperm head to disconnect from its flagellum as the egg travels down the fallopian tube to reach the uterus.
Formation of Zygote: The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development.
This process can also occur outside of the body through methods like in vitro fertilization.

Human fertilization occurs when sperm and egg cells unite to form a zygote, the first stage of human development. During sexual reproduction, sperm is ejaculated into the female reproductive system where it travels through the fallopian tubes to meet the egg. If a sperm successfully penetrates and fertilizes the egg, it implants into the uterus, beginning the process of pregnancy.

∙ 10y agoIn the human fertilization process, the sperm which reach the egg fight for entrance. Once entrance has been gained by a single sperm, the rest are pushed away and die within 48 hours. You can learn more about this process at the How Stuff Works website.
