ICSI  (the Intracytoplasmic Sperm Injection)

Depending on the cause of infertility in couples, there are several options for getting pregnant with the help of reproductive medicine. Fertilization by ICSI  (the Intracytoplasmic Sperm Injection) -  ICSI - intracytoplasmic sperm injection into the egg. In other words, it is the introduction of the injection with the sperm directly into the egg. Such a procedure is usually used in cases where the IVF method did not work, as well as in the case of infertility in men.

Differences of ICSI from IVF

The ICSI procedure differs from IVF by the method of interaction of a biological sample with a female germ cell. During IVF, spermatozoa are placed in a separate container along with the eggs, where the process of fertilization of the egg takes place independently.

In the case of ICSI, manual insertion (by injection) of the most active sperm directly into the immature egg cell (oocyte) under a microscope takes place. Sometimes, a combined eco-ixi method is planned, when, after the eco-procedure, the ixi procedure is carried out to secure the results under the supervision of a keen embryologist.

When should ICSI be performed

ICSI fertilization is considered more selective because this method in a compulsory form "forces" the sperm to fertilize an egg cell. Usually, many couples have resorted to achieving pregnancy using the eco method, while xyxis are considered if there are such indications:

  • Low activity and insufficient sperm count, which is determined by the spermogram.

  • The presence of azoospermia - when spermatozoa are absent in the seminal fluid for fertilization.

  • The presence of antisperm antibodies in seminal fluid.

  • Low proportion of active fertilizable sperm.

  • In the case of unsuccessful eco, which resulted in a low fertilization rate.

  • Diagnosing infertility of unexplained origin.

  • Pathology of the vas deferens.
