ICSI: The modus operandi
We hold the matured eggs using a special pipette. It is designed to hold the eggs in a better and organized manner.
A sharp and delicate hollow needle is used to pick up a single sperm in immobilized state.
The needle with sperm is injected to the shell of the female egg called as Zona. The sperm is injected in the inner part of the eggs called as cytoplasm. This is centre of the egg.
The eggs are monitored next day to ensure normal fertilization.
ICSI: The success story
We need to understand that there are two aspects of success when we think about IVF programs. The first one is known as fertilization rate and the other one is known as pregnancy success rate. In case of fertilization rate, we consider the process of fertilization. There are around 70 to 80 percent cases where fertilization happens after the ICSI process. The rate is significantly high on any parameter.
Pregnancy success rate is the rate of a successful pregnancy until the childbirth. IVF using ICSI method is more successful as compared to IVF using the other methods. The reason is simple, in case of ICSI, the woman is more fertile, the age is relatively less, the overall health and fitness is better and the average quality and quantity of eggs is better. Success rate is obviously higher because of these reasons. However, there are some cases of unexplained infertility that lowers the chances of successful pregnancy using ICSI.
There are some other aspects as well. IVF using ICSI is a complex procedure and I need to apply the skill and expertise to achieve success. The quality of the treatment, laboratory, equipment, and skill of my team are the other aspects that denote the success.
