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.
Under optimum conditions a fertilized egg can be kept for up to 10 days with some chance of a viable hatch. The sooner used after lay the better but viability drops with warm conditions and low humidity. After seven days storage, 70% viability is reached and a further 10% per day thereafter.
