Intracyptoplasmic sperm injection (ICSI)

Intracytoplasmic sperm injection (ICSI), a further development of IVF, differs from normal IVF in that the union of the retrieved eggs with the sperm of the spouse is carried out under a special microscope.

Here, a single sperm cell is injected into an egg cell by means of a wafer-thin glass capillary. The other steps of ICSI treatment, such as hormonal ovarian stimulation or egg collection, are the same as in normal IVF. ICSI is mainly used when the number, motility and external appearance of the sperm cells are very limited.
