What is the difference between icsi and imsi

In some cases the sperm has to be injected directly inside the egg. ICSI is used when a problem or potential problem with the sperm has been identified during the phase of investigations. We are absolutely overjoyed. We would very much like to express our gratitude to yourself and all of your staff at Reproductive Health Group who have helped to make this dream come true for us.

The professionalism and empathy shown by each and everyone of you was second to none. IMSI uses a high powered lens to look at sperm under very high magnification and allows the embryologists to see greater detail during the sperm selection process.

Achieving a healthy pregnancy is hugely dependent on the quality of the human embryo. The quality of an embryo is a product of the quality of both the egg and the sperm. If sperm have abnormalities they can still create an embryos but these are unlikely to implant or may result in an early miscarriage.

Some sperm abnormalities can be identified using a microscope which magnifies up to x With IMSI the magnification is up to x, which enables the embryologists to see more accurately abnormalities in the head of the sperm. By selecting sperm without abnormalities, the chance of creating better quality embryos is higher. There have been several studies within the last decade that suggest that IMSI could be beneficial in specific situations such as previously failed ICSI attempts.

Meanwhile, IMSI Intracytoplasmic morphologically selected sperm injection refers to a laboratory technique used for i n vitro fertilization treatments in which high-quality sperms are injected into the egg for fertilization ; it is an advanced version of ICSI.

In brief, ICSI intracytoplasmic sperm injection is a modification of IVF where a single sperm is enough for the fertilization of an egg cell. Also, it avoids the occurrence of the acrosome reaction as in traditional IVF. Meanwhile, IMSI intracytoplasmic morphologically selected sperm injection is an advanced method of ICSI where the sperm selection occurs for the fertilization under high magnification.

Therefore, it always associates with high pregnancy rates as the process uses high-quality sperms. Kim, Hyung Jun et al. WikiJournal of Medicine 1 2.
