At one ejaculation, about 200 to 500 million sperm are ejaculated into the vagina. Of the 200 to 500 million sperm, the sperm that swims the fastest can be fertilized by meeting a single egg in the fallopian tube.

In the fallopian tube, one sperm and one egg meet to form a fertilized egg.
The fertilized egg begins to divide into two cells, and two cells divide into four cells, and when it becomes more than 16 cells, it enters the uterus and implants on the wall of the uterus.
This phenomenon is called pregnancy. a-embryo implanted in the uterus wall Source-Pregnancy in Anatomical Illustrations, Carnation Healthcare Services, Los Angeles. CA 1962
