ICSI

A revolution in the male infertility was the news in the 1992 about first pregnancies achieved by injecting single sperm in to the egg through its shell (zona pellucida). This method helps countless couples who’s cases were hopeless and were forced to use a donor sperm only few years before. The method of "intracytoplasmatic injection of sperm (ICSI)" is a elaborate micromanipulation technique when the sperm is aspirated in to a thin sharp glass capillary and inserted in to an egg through its shell.

Indication for ICSI is the inability of the sperm to fertilize the egg spontaneously (low count, low motility), immunological causes of infertility, failing of classical IVF cycles, later age, low amount of matured eggs, when cryo-preserved sperm is used or when the sperm is collected by MESA/TESE method, when donors eggs are used etc. This method has a very high success rate of fertilization. The patient has to indeed undergo the normal procedure of super-ovulation and egg retrieval and the partner has to provide the sperm. In the view of collected data we can say that by fertilization of the egg using this method is not increased risk of a child with congenital developmental defect when compared to spontaneous conception.
