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 egg can be fertilized for up to 24 hours after ovulation. If it isnât fertilized the lining of the womb is shed and your period begins. This marks the start of the next cycle.While an egg is only viable for about 24 hours, sperm can remain active for up to five days. The soâcalled LH surge causes the release of the egg from the ovary and youâre ovulating. 2  Ovulation normally occurs 24 to 36 hours after the LH surge, which is why LH is a good predictor for peak fertility.
