Conception and Implantation: The Beginning of Life - Fertilization: A sperm fertilizes an egg in the fallopian tube, forming a zygote. This single cell contains all the genetic material needed for a new human being. - Cell Division: The zygote undergoes multiple cell divisions (cleavage), becoming a morula and then a blastocyst around 4-5 days post-fertilization. - Implantation: The blastocyst implants itself into the uterine wall (endometrium) around 6-7 days post-fertilization, establishing a connection with the mother.
