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 number of eggs that can be fertilized depends on the parents' ages. The doe and buck have maximum egg/sperm production between the ages of 6 months and 3 years. After this, egg/sperm production decreases, as does the chances of conception and bringing the little ones to birth. Temperature extremes decreases the chances of conception.
