Microinjection (ICSI)

In cases of a very low sperm count or if there is any other major abnormality in the sperm analysis, microinjection of one sperm into the oocyte can be used. An oocyte obtained after retrieval is fixed in a holding pipette under microscopic control. Using micromanipulators one single sperm is injected into the cytoplasm of the oocyte. Cultivation is performed for two days as at conventional IVF.
