What is Understanding Fertilization Process about?
Fertilization is the union of sperm and egg to form an embryo, occurring in the fallopian tubes after sperm travel from the vagina. Approximately 300 million sperm are released during intercourse, taking 45 minutes to 12 hours to reach the fallopian tubes, where only one sperm can penetrate the egg due to chromosome importance. The zona pellucida surrounds the egg, facilitating sperm entry and protecting them, leading to cell division once fertilization occurs.
