Donor egg cells and frozen egg cells in-vitro fertilisation method

In case of donor egg cells and frozen egg cells it is necessary to use the ICSI (Intracytoplasmic Sperm Injection) method, during which one sperm cell is injected to each egg cell by using a micro manipulator.

After the ISCSI procedure, the embryos are grown in a laboratory for 2–6 days after which 1–3 embryos are transferred to the uterus.
