Embryo donation in Spain is regulated by the Law n. 14/2006 of May 26th about Assisted Human Reproduction Techniques and by the Royal Decree 1301/2006, both derive from the European directives 2004/23/CE, 2006/17//CE and 2006/86/CE regarding the donation of human tissues and cells.


The Institute for Reproductive Medicine (IMER) is recognized by the EU and by the Spanish health authorities as an authorized center for the storage, manipulation and transfer of gametes and embryos to other clinics in Spain and other EU countries, that require them to perform medically assisted reproduction treatments.


Embryo donation is a voluntary, altruistic and anonymous act, therefore receiving  patients are not allowed to bring or select the donors. Choosing the most compatible embryos is the sole responsibility of the medical team following the treatment. All the effort will be made to obtain the maximum possible immunological and phenotypic compatibility of the embryos with the receiving patients. Receiving patients and their descendants have the right to request general information about their donor, but not the identity.


IMERbiobank embryos come from couples who have undergone fertility treatments and have cryopreserved surplus embryos for future treatments. In fact, very often, when these couples achieve a pregnancy and after the birth of their child, they decide to donate the remaining embryos to IMERbiobank in order to be used in assisted reproduction treatment for other couples.


Apply for donation



IMERbiobank’s cryopreserved embryos originate from couples that received fertility treatments in our own clinic, whose woman does not exceed 35 years of age at the time of donation, and that after achieving a pregnancy decide to donate the surplus embryos. Thus the donors at the time of treatment that originated the embryos, undergo meticulous and exhaustive medical tests, including:


  • Clinical history and medical visits to assess personal and family history of the donor.

  • Serological Analytics to rule out the possibility that donors are carriers of infectious diseases: Hepatitis B, Hepatitis C, HIV, Syphilis, Ab anti- Cytomegalovirus IgG, IgM etc.

  • Karyotype: assessment of chromosomal and genetic normality.

  • Biochemical Profile, full CBC and study of blood coagulation.

  • Semen analysis.

  • Semen culture, urine culture, search for Neisseria Gonorrhoeae, Mycoplasma Hominis, Ureaplasma Urealyticum and Chlamydia Trachomatis.

  • Blood group and Rh factor.
