One of the important considerations is the fertilization of the eggs. There are 2 different choices
- Standard insemination
- Intracytoplasmic sperm injection
Conventional Insemination
In this method, the egg is surrounded by the sperm in a petri-dish and this fertilizes at least one egg. With the conventional method the best sperm wins which help in the conception process. But, in around 10 to 15 % of cases, there is the issue of TFF (Total Fertilization Failure) which no one egg is fertilized. In this case, it is important for the sperm to be motile and good quality.
ICSI
Another method is intracytoplasmic sperm injection in which a single sperm is selected by the embryologist which will be injected into the egg directly. The sperm are selected individually by determining their health and then injected into the egg.
In this method, even if the sperm count and quality do not matter as they are injected so there is no issue of the sperm to travel or penetrate the egg.
What should the couple choose?
- In the past few years, the demand for ICSI has increased a lot. Many people are choosing this because they worry that there will be no fertilized egg with a standard approach.
However, fertilization failure with the conventional method is just 5%. Whereas in other methods the fertilization failure is around 2%.
- Importantly, studies have been done even if the sperm is normal the success rate is the same as with other methods.
- There are few situations in which this option is needed like the sperm issue, genetic testing of the embryos (PGS), or the couple failed with standard insemination in the past. In these cases, these methods are best.
Well, the fertilization failure can be avoided as your fertility doctor will determine whether the egg and sperm can fertilize. Your fertility doctor will determine by diagnosing your condition and help you decide which option will be ideal for you between the two.
