The entire process lasts from 4 to more than 10 weeks, and the first 2 to 3 weeks are part of the qualification process. The qualification requires one or two visits to the Clinic, test results, and consulting a psychologist and a gynaecologist. Each time, the staff makes every effort to organise the qualification in an optimal way and without burdening the potential donor. After the entire process has been successfully completed, the date for taking further steps (hormonal stimulation, procedure) is arranged individually, depending on the type of treatment in which the material from the donor is to be used.
