From the Paper:

"Once the sperm and ovum meet, a zygote is formed with a set of forty-six chromosomes. In just a few hours, this zygote multiplies into two cells, then four, eight, etc. This large clump of cells is known as the morula. The morula will for the next four days continue on to travel through the Fallopian tubes. The sphincter, which is usually impenetrable, relaxes due to progesterone allowing this hollow clump of cells, now known as a blastocyte, to pass through and attach itself to the lining of the uterus. This step is called implantation."
