Fertilization and Embryo Development. Following ovulation, the egg is capable of fertilization for only 12 to 24 hours. Contact between the egg and sperm is random. Once the egg arrives at a specific portion of the tube, called the ampullar-isthmic junction, it rests for another thirty hours. Fertilization â sperm union with the egg â occurs in this portion of the tube. The fertilized egg then begins a rapid descent to the uterus.
Once a sperm reaches (burrows into) the egg, you have fertilization, right there. Implantation is when the fertilized egg implants in the uterus. For this to happen the fertilized egg has to travel down the fallopian tube, into the uterus and then implant. This process cant take 6 - 12 days.sker's rating. Report Abuse.

The sperm and egg meet up in the fallopian tube and then travel down into the uterus for implantation. Implantation can take 6-12 days after ovulation.
