The semen samples are stored in a frozen state in semen banks and are kept in quarantine for a period of 6 months to control the risk of any diseases being passed on. After this time the tests are repeated in order to ensure that the donor is not in the early stages of an infection.
The selection of semen donors is controlled by law and includes men over the age of 18 who have a good state of physical and mental health, who test negative for infectious diseases and who have a normal karyotype. The selection procedure also includes genetic tests and a medical history of donors and their families, in order to prevent the risk of genetic diseases being passed on to their descendants.
Finally, in the IVI clinics, once it has been checked that there are no infections and that the semen has tolerated the freezing process sufficiently and maintained its quality, the samples are made available for use in fertility treatments, whether for intrauterine insemination, an IVF cycle or ovodonation.
