Intracytoplasmic morphologically selected sperm injection (IMSI)
According to records, the inability to conceive is male infertility problems in nearly 40% of cases—the issues like low sperm count, abnormality of sperm, and low sperm quality. In some cases, the sperm samples are low, or the sperm abnormality is relatively high, and therefore ICSI doesn’t give good results. In such situations, Intracytoplasmic morphologically selected sperm injection (IMSI) is used to treat the problem.
IMSI is an improved version of ICSI for better results. The difference here is that the microscope used in this method examines sperm with a magnification of up to 6,000x. These highly magnified and digitally enhanced images of sperm help the embryologist locate any kind of abnormalities or problems with sperm that couldn’t be identified by using other older methods.
Intracytoplasmic morphologically selected sperm injection (IMSI) is a technique that is similar to ICSI. The only difference is that sperm is examined more carefully to find out a good quality sperm that can give the best results and help couples conceive.
Using this method over other conventional methods helps find and prevent sperm with abnormalities from injecting into the egg that can further cause pregnancy failure. Thus, this method helps in increasing the success rate of infertility treatment.
When is IMSI recommended?
There are many other conventional methods available in clinics, and therefore this method is considered in the least cases. The first case is when the number of sperm is deficient, which leads to infertility in a male. The second case is when the proportion of abnormal sperm is very high, which prevents conception. And the third reason is multiple failures of conventional methods and ICSI. So, this IMSI treatment in India is done when the conventional techniques can’t be used, or the success rate is shallow with those methods.
IVF and IMSI Treatment
IMSI treatment helps increase the success rate of IVF treatment. After retrieval, the sperm is examined under a high magnification microscope at the fertility center’s lab. This intense digital examination helps the doctors to identify abnormally shaped sperm cells and prevent them from injecting into the egg. The method allows the doctor to check the structure and quality of sperm deeper than ICSI and increases the chances of injecting the right sperm in the egg to enhance the success rate. This is just an improved variation of ICSI where the complete procedure is the same, and only the magnification of the microscope is different.
Procedure of IMSI
This procedure is just a better option in comparison to ICSI to increase the success of the IVF procedure. This method is to be used after several unsuccessful IVF attempts. This method is real-time because the perfect quality sperm is selected before the microinjection to increase the effectiveness. It is to make sure that the developing embryo will be of good quality, and there is no need to wait for a healthy embryo because of efforts are made to develop a healthy embryo only.
When the sperm is analyzed under a high magnification microscope at the fertility center, the specialist can clearly see the sperm’s sperm’s internal morphology of the sperm clearly, thus finding abnormal cells becomes easy. It further increases the chances of successful embryo implantation, and chances of miscarriage are likely to be decreased with this method.
IMSI – how much we recommend this method?
This method requires more attention and evidence to be used regularly for the treatment of infertility. More studies about the technique are still needed to be used in routine by doctors.
Benefits of going for IMSI
It is useful to increase the chances of conception with in vitro fertilization technique and is recommended if you have many unsuccessful IVF attempts
