According to Article 8 remunerated donation of ova or fertilized ova (embryo) donation is prohibited. Such donation is only permitted for medically assisted reproduction purposes. Consent is required. Only supernumerary embryos can become the object of donation and only adult persons can become donors. All medical data concerning the donor(s) are stored in a codified form. Donated material undergoes various medical/laboratory controls, as specified by law. Research can take place in supernumerary human gametes or fertilized ova, which have been donated for this purpose. Donated material which has been used for research purposes cannot be used for the achievement of a pregnancy (Article 11), unless the purpose of the research concerns successful implantation of a fertilized ovum or the birth of a healthy child (Article 12). For such research to be carried out, permission from the National Authority on Medically Assisted Reproduction is required.
