How Fertilization happens, 3 D Animation

This 3D animation shows the magic that happens when a sperm meets an egg and the sparks fly. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining (a process known as implantation ). Timecodes: 0:00 Ovulation 0:15 Union of Sperm and Egg 0:35 Mitosis 0:48 Blastocyst 1:02 Implantation 1:14 Next video
