How Fertilization happens | 3D Animation

Sperm Penetration and Egg Protection00:00:15

Once a sperm penetrates the egg, the egg undergoes a chemical reaction to prevent other sperm from entering. The chromosomes from the sperm and egg then combine, officially fertilizing the egg.

Journey to the Uterus and Embryonic Development00:00:35

The fertilized egg rapidly descends to the uterus. Over seven days, the embryo undergoes multiple cell divisions through mitosis, forming a blastocyst, a mass of organized cells.

Implantation of the Blastocyst00:00:55

Around five to six days after fertilization, the blastocyst breaks out of its protective covering and begins to implant itself in the uterus.

The Race to Fertilization00:00:00

Each month, a woman releases a single egg, while a man releases millions of sperm in a single ejaculation. Only one of these sperm will successfully fertilize the egg.
