ICSI (Intracytoplasmic sperm injection) is an infertility treatment performed as part of the IVF procedure. In this process a single sperm is microscopically injected directly into the cytoplasm of an oocyte, using a special needle. Previously, all the cells surrounding the oocyte must be removed.

ICSI is a good option for patients in whom  fertilization of the oocytes cannot occur spontaneously. It is in cases of  severe oligoasthenospermia or azoospermia, in cases of frozen sperm use and in older women who produce few oocytes with low fertilization capacity.

Fertilization rates with ICSI reach 50-80%, and in some cases 100%. Pregnancy rates are higher compared to IVF, as well.

This revolutionary method was introduced in Greece for the first time by our Center, with great success, in collaboration with Professor Michael J. Tucker (Director of IVF and Embryology Laboratories Shady Grove Fertility Reproductive Science Center), who had achieved the first pregnancy in the USA using this method.
