ICSI (intracytoplasmic sperm injection)
Mikroinjection
. The intracytoplasmic sperm injection (ICSI) has been successfully applied since 1992. In the case of a classical IVF procedure, thousands of motile sperms are needed in order to fertilize the egg. The ICSI method requires only a single, alive sperm cell. With the help of a fine glass cannula, the sperm cell is injected directly into the egg cell and can induce fertilisation there. ICSI is especially suited for the treatment of patients with an extremely strongly reduced sperm quality.
1 Injection of a sperm cell
. A single sperm is injected directly into the egg cell. After that the fertilisation and the nuclear fusion is possible later. With the help of this method a pregnancy can be occur even when only few and/or immotile sperms are available.

. This treatment method can be successful even in the cases when retrieving sperms from the testicles or the epididymis is only possible by a surgical intervention. According to the existing data based on experience with this method (since 1991) there is no increased risk of malformation for the children conceived after ICSI. A preliminary genetic consultation and examination is nevertheless recommended to the affected couples as a common prevention measure (high risk of genetically caused reproductive disorders in this treatment group).
