Intracytoplasmic Sperm Injections were introduced to treat male infertility. It helps men father a child genetically without adoption or working with sperm donors. This assisted reproductive technology has an exceptional success rate of 80-85% and is just as effective as IVF. In the traditional In Vitro Fertilization, the eggs are fertilized naturally in the lab. However, in case the gametes are unable to fuse, embryologists can suggest this microsurgical procedure.
A tiny needle is used to inject a sperm directly into the cytoplasm. Once fertilization occurs, the egg grows in the laboratory for around 5 days. After an embryo has been formed, it is placed into the uterus hoping for implantation. There are rare complications, and it is one of the safest methods to improve the odds at pregnancy. However, doctors do not recommend ICSI in Bangalore or other cities for everyone. Have a look at when it might be ideal for you.
Poor Sperm Motility
In this case, the sperm does not swim well enough to reach the egg. Sometimes, they can simply die before reaching the ovum. So, there are high chances that they might not be able to move near the eggs in the lab dish as well. In this case, an ICSI can be suggested by the doctor to help a sperm enter the egg.
In top infertility treatments in Bangalore, a good number of eggs and sperms are retrieved. In fact, both the gametes are healthy with proper structure and shape. However, due to unexplained reasons, the eggs do not get fertilized in the IVF cycle. At this point, the fertility specialist can suggest an ICSI to improve the chances of pregnancy. This is also an option in case the sperms are healthy but eggs have defected chromosomes which prevents fertilization.
Vitrified embryos are subjected to 5-10 times more cryoprotectant than the ones exposed to slow freezing. This leads to hardening of the zona pellucida which is the outer layer of the egg. It can bring in certain complications in the IVF process. For example, sperms might not be able to pierce through the shell and reach the cytoplasm. This can stop the fertilization process and keep you from achieving pregnancy. ICSI is used to place the sperm inside the egg thus facilitating fusion.
Low Fertilization Rate
This is linked with DNA malfunctions in the male germ line leading to unsuccessful IVF process. Also, a round or oval headed sperm might not be able to activate the oocyte which is once again a cause of failed fertilization. Further, if the egg does not have the right structure to build an embryo, an IVF process can fail. So, if these incidents have occurred in previous fertility attempts, an embryologist will prefer using an ICSI for the next cycle of infertility treatment in Bangalore. Preimplantation Genetic Diagnosis (PGD), Testicular Sperm Extraction and In Vitro Maturation also require an ICSI. It is a highly advanced method and has produced excellent results in the past. However, make sure to be well informed about procedure and side effects for a practical decision.
