What is the difference between the first, second, and third generations of IVF?

Now that IVF is already a hot word on the Internet, do you know what the difference between the first, second and third generations of IVF is?

The first generation of IVF, in vitro fertilization, embryo transfer, we take the eggs out, through the way of ovulation and natural combination with the laboratory sperm, so that the closest to the natural conception of the embryo development.

The combination of sperm and egg is equivalent to thousands of troops crossing the canoe bridge to break through the siege and reach the other shore, which must be of high quality. However, there is nothing that can be done if the man is weak and azophroparated.

Second-generation IVF, which is called intravellicular plasma single sperm microinjection. It can put a single high-quality sperm into the plasma cells of the egg and fertilize the egg, and if the sperm and egg cannot actively accept the sperm, then the doctor will use this method to help them.

The difference between the third generation of IVF and the previous one is that the doctor will take the embryo to test the genetics to see if there is a chromosomal disease, and if there is a problem, it will be eliminated to help the couple conceive a healthy baby.

The three generations are just different groups that adapt, and does not mean that the latter is better than the front.
