This usually happens in the fallopian tube, where the sperm meets the egg after traveling through the reproductive tract. The fertilized egg, now called a zygote, begins to divide and grow, forming a ball of cells called a blastocyst. Implantation: The Blastocyst's Journey The blastocyst travels down the fallopian tube and into the uterus, where it implants itself in the uterine lining. This process is called implantation, and it's crucial for the development of the embryo. The implanted blastocyst begins to produce human chorionic gonadotropin (hCG), which helps maintain pregnancy.
