ICSI

ICSI is an  intracytoplasmic  injection of  a spermatozoid into an oocyte during the  in vitro fertilization (IVF).

ICSI is the operation carried out by specialists of our center giving a man the possibility to have genetically related child.

Indications for  ICSI:

• oligospermia - concentration of spermatozoa is less than 10 mln/ml;
• asthenozoospermia – less than 1 mln of active, mobile spermatozoa in 1 ml;
• teratozoospermia - less than 5% of normal forms according to the data of morphological analysis under Krueger;
• azoospermia – the absence of mature spermatozoa in the ejaculate, if mobile spermatozoa were revealed at puncture of an ovary or its epididymis;
• overlapping pathology of sperm;
• clinically essential availability of sperm-coating antibodies in the ejaculate (MAR-test is more than 50%);
• cryopreserved spermatozoa having low parameters after defrost;

During the IVF +ICSI , the male partner or a donor provides a sperm sample on the same day when the eggs are collected. The sample is checked in the lab, and if no sperm of good quality is present, doctors will extract sperm from the epididymis or testicle. The extraction of sperm from the epididymis is also known as percutaneous epididymal sperm aspiration (PESA) and extraction of sperm from testicle is also known as testicular sperm aspiration (TESA).
