One egg and one sperm unite at conception.Fertilization, takes place in the woman's fallopian tube and the fertilized egg divides into about 12 to 16 cells on its journey through the fallopian tube to reach and implant in the uterus.
-
After it is released, the egg travels down a fallopian tube toward the uterus. If the egg meets a sperm, they combine to form one cell. This is called fertilization. Fertilization is most likely to occur when a woman has unprotected intercourse during the 6 days that lead into ovulation.Pregnancy begins when the ball of cells attaches to the lining of the uterus.
