ICSI (Intracytoplasmic Sperm Injection)
In vitro fertilization using the ICSI method is a technique that involves the introduction of a previously selected sperm cell directly into the patient's egg cell.
Intracytoplasmic sperm injection is most often recommended for couples qualified for in vitro fertilisation who were found infertile due to the male factor.
It is effective also in the case of the female factor, e.g. in endometriosis, premature ovarian failure and in immunological infertility, where the probability of cell fertilization and success using the classic IVF fertilization method is reduced. The method is used in cases of infertility of unknown origin (idiopathic one). In this case, a mixed procedure is usually used, which consists of a fertilisation attempt of part of the egg cells using the classic method and the fertilization of others using the ICSI method.
Indications for the in vitro procedure using ICSI:
- male infertility factor - low percentage of motile sperm cells or their low concentration may contribute to difficulties in reaching and fertilizing the egg cell in natural conditions,
- male infertility factor - sperm cells collected directly from the testicles, after the diagnosis of azoospermia, i.e. absence of sperm in the ejaculate,
- infertility of immunological origin,
- low ovarian reserve, premature ovarian failure,
- idiopathic infertility,
- failure of the preceding IVF cycle using the classic fertilization method.
The effectiveness of ICSI in vitro fertilization is similar to the "classic" in vitro fertilization and depends, among other things, on the patient's age and the quality of her egg cells.
