Frozen eggs, also known as frozen eggs. For young and healthy women who do not want to have children, freezing eggs becomes a good choice. So how do frozen eggs become fertilized eggs?
Freezing eggs is the process of taking healthy eggs from the mother's body and freezing them to prevent them from aging with the body. The frozen eggs can be taken out and used when fertility is desired. There are two ways to preserve eggs. The first method is to store the egg in a dehydrated solution, then slowly freeze it using a computer system, and finally seal it in ultra cold liquefied nitrogen. Another way of updating is to place the eggs in a highly concentrated dehydrated solution and immediately store them in the same formula of liquefied nitrogen.
How does an egg conceive into a fertilized egg?
Step 1: Egg Thawing
When eggs need to be used, they can be retrieved from liquefied nitrogen and treated with gradient drugs. The recovery process can be quickly completed by using drugs of corresponding concentrations and osmotic pressures from high to low.
Step 2: Sperm Processing
From the extracted sperm of the husband's side, microscopic observation was used to capture the most beautiful and energetic "tadpole" and arrest it. Inhale the syringe with a needle.
Step 3: Single sperm injection of egg
Inject the captured active sperm into the egg to complete the in vitro assisted reproductive procedure.
Step 4: Fertilized Egg and Embryo Culture
After fertilization, the embryo is cultured in a specific environment for 3-5 days. Considering the time and speed of cell division, the initial single fertilized egg usually divides into approximately 8 cells on the third day. Subsequently, it enters a rapid division phase, and the number of cells increases in a collective order. On the 5th day, when it has developed into 2 cells to the power of N, it is considered a qualified embryo.
Step 5: Embryo implantation
Select suitable embryos and implant them into the female uterine cavity. After 15 days, perform a pregnancy test to determine if the child has been successfully conceived.
For those who are not married or infertile, choosing frozen eggs as a possible "regret medicine" in the future is a safe approach. But rather than calling it insurance, it's more like buying lottery tickets. Whether or not one can "win the big prize" depends on personal luck. Because eggs can suffer certain damage after freezing, the success rate of conception will decrease. It is an undeniable fact that the success rate of conception with frozen eggs is low.
