The chance of IVF success is not 100%, and there are many reasons that affect the success rate of IVF, and IVF abnormalities are also one of them. A key step in IVF itself is to perform in vitro fertilization, which allows the male sperm and the female egg to combine together to become a fertilized egg through external help, and then develop into an embryo. So how to remedy abnormal IVF countermeasures, IVF abnormality?
Causes of IVF abnormalities
1. Sperm and egg factors, if the sperm is of poor quality, the malformation rate is too high, etc., and the quality of the egg is also due to age, it will lead to abnormal fertilization of the sperm and egg.
2. Chromosomal abnormality, this situation has a certain degree of secrecy, if the couple does not do chromosomal screening, it may be difficult to find this problem.
Countermeasures against abnormal IVF fertilization
1. To improve the quality of sperm and eggs, both husband and wife should improve their living habits and improve the quality of sperm and eggs with the help of doctors.
2. Change the fertilization method, according to the actual situation of the patient, change the fertilization method to increase the probability of success.
3. Change the stimulation program, clinically found that the stimulation program of IVF women also has a certain impact on the success of fertilization, so you can consider changing the stimulation program, such as changing the stimulation drug, adjusting the dose of stimulation drugs, etc., to improve the probability of successful fertilization through these methods.
Time to remedy IVF abnormalities
The best time for IVF abnormality is about 6-8 hours after sperm is added to the egg. Fertilization is a very complex process of combining sperm and egg, and it is difficult to ** whether the egg and sperm can be fertilized normally and naturally outside the body. Therefore, in order to avoid the outcome of fertilization failure and total annihilation, sometimes embryologists will use the second generation of IVF technology to inject sperm into the ovar for IVF cycles with complete infertilization or low fertilization rate, which is called remedial ICSI.
In short, the countermeasures for IVF abnormalities include improving the quality of sperm and eggs, changing the fertilization method, changing the stimulation plan, etc., of course, the best time for IVF abnormal remediation is about 6-8 hours after adding sperm to the egg.
