How is ICSI conducted?
The use of this technique allows you to solve that seemingly desperate situation, when conception does not occur due to infertility in men. For an intracytoplasmic injection of a sperm into a female germ cell, oocyte, a sperm corresponding to the norm is selected.
For carrying out the manipulation, a microscope with a large optical magnification is used, which has a special plate with a thermoregulator, i.e. constantly has a temperature of about 37 degrees. To the very microscope attach special micromanipulators, which allows you to move the micropipette in all directions.
How is sperm selection performed for ICSI?
This kind of technique undergoes improvements almost every year. It allows to make a morphological evaluation of the male sexual cell and choose the most suitable for implantation.
It is also possible to conduct a so-called physiological ICSI. This uses hyaluronic acid, which helps to identify the most mature spermatozoa in the ejaculate. All this allows us to radically reduce the likelihood of developing genetic abnormalities, in particular those that develop when the ovum is fertilized with a damaged, not fully formed sperm.
Thus, it must be said that ICSI allows the exclusion of fertilization, the so-called pre-apoptotic spermatozoa, i.e. Those that would cause a halt to programmed development.
