ICSI (Intracytoplasmic Sperm Injection) - intracytoplasmic sperm injection

In vitro fertilisation by ICSI is a technique that involves the insertion of a pre-selected sperm directly into the patient's egg cell.

What is ICSI?

ICSI, or intra-cytoplasmic injection (injection) sperm is recommended most often to couples qualified for the in vitro fertilisation procedure who have been diagnosed with male factor infertility.

Also effectively used in cases of female factor e.g. endometriosis, premature extinction of ovarian function and immune-mediated infertility, where the likelihood of cell fertilisation and success with the use of the classic method of IVF fertilisation is reduced. The method is used in cases of infertility of unknown origin (idiopathic). In this case, a mixed procedure is usually used, which involves attempting to fertilise some of the ova using the classical method and the rest using ICSI.

Indications for IVF using ICSI:

  • male factor of infertility - a low percentage of motile sperm or a low concentration of sperm can contribute to difficulties in reaching and fertilising an egg under natural conditions,

  • male factor of infertility - sperm collected directly from the testes, following a diagnosis of azoospermia, i.e. absence of sperm in the ejaculate,

  • immune-mediated infertility,

  • endometriosis

  • low ovarian reserve, premature extinction of ovarian function,

  • idiopathic infertility,

  • failure of the preceding IVF cycle using the classical method of fertilisation.

Effectiveness of ICSI

The success rate of ICSI in vitro fertilisation is similar to 'classic' IVF and depends, among other things, on the age of the patient and the quality of the oocytes she has.
