After sperm cells are deposited inside a woman, the sperm rapidly swim through the uterus, through the tubes, and out the ovary. This passage can take as little as 30 minutes. If the woman has ovulated and an egg awaits, fertilization occurs immediately – LIFE begins! Fertilization is the exact moment when a new human being comes into existence.

This one-celled life has inherited 23 chromosomes from each parent and contains the entire genetic code for every detail of individual human development. It has its own genetically distinct DNA and may have a completely different blood type (not to mention sex) than the mother. From sperm entrance until the first cell division takes place IS ABOUT ONE DAY. From then on, rapid cell division occurs.
