What is IMSI Technique?

The aim of IMSI, that is, Selected Sperm Microinjection with High Microscopic Magnification, is to determine and select the best quality sperm and to ensure fertilization with eggs. High fertilization rates are obtained with the IMSI method. Determining and choosing the best quality sperm will also affect embryo development and increase the patient’s chance of pregnancy.

Today, in IVF treatments, sperm are selected under a special microscope and injected into the egg with the ICSI method. In order to obtain quality embryos during this process, embryologists select sperm for fertilization by paying attention to the shape of the moving tail and head of the sperm.

Microscopes, which are classically used in sperm selection, magnify the sperm up to 400 times and help in the selection of sperm. In this way, the best quality sperm with the best fertilization ability can be selected.

IMSI Technique and IVF

Especially the changes in the head of the sperm determine the quality of the sperm, and attention is paid to cellular changes such as a bubble-shaped vacuole in this region.

This method is preferred especially in cases of “male factor” or “unexplained infertility”.

In our center, microinjection is applied to patient groups with severe sperm factor using the IMSI technique at no additional cost.

What are the Advantages of the IMSI Technique?

  • Since sperm can be examined in more detail with IMSI microscope, it allows the selection of the healthiest sperm.
  • With the IMSI technique, the egg fertilization rate is increased.
  • The possibility of miscarriage is low in pregnancies that occur.
  • Since the best quality sperm is determined morphologically, genetic disorders occur less frequently.
  • It increases the chance of success in patients with low sperm count and quality.


In Which Patients Is IMSI Technique Preferred?

  •  In patients with normal sperm morphology as “0” as a result of spermiogram,
  •  In men over the age of 35,
  • In patients who cannot obtain quality embryos despite obtaining a good number and quality of eggs,
  •  In patients who have undergone IVF treatment many times and have negative results,
  • It is a preferred method in patients who have experienced miscarriage in previous IVF trials..
