[00:00:00]Ever wondered how a baby actually begins inside the human body? It all starts with a microscopic cell called sperm meeting an egg inside the female body.

[00:00:09]When one sperm successfully enters the egg, fertilization happens, creating the very first cell of a baby. This single cell begins dividing rapidly, forming a tiny cluster that travels to the uterus.
