Assisted reproduction techniques

High-complexity techniques

ICSI

This procedure is applied in cases of severe male factor infertility, where sperm quantity and motility are very poor or when there are no sperms in the semen (in which case sperms are taken directly from testicles or epididymes.) Once the eggs are in the laboratory culture, and the semen sample has undergone a special treatment, one single sperm is microinjected into the egg cytoplasm. This technique overcomes any fertilization impediment, with the ensuing development of embryos in patients with very poor sperms. Once microinjected, the egg is placed in the same culture as IVF. Resulting embryos are then transferred also in the same way as in IVF.
