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.
The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours. The fertilized egg then undergoes several divisions to form a structure called the zygote. It moves into the uterus within a period of 5-7 days and is then termed as embryo.he length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.
