Donor Gametes

There are many cases in which a sperm or eggs / a donor in the field of assisted reproduction is used.



Common causes in respect of which need to resort to sperm donation:

Heterosexual couples in the following cases:                                                           

  • Mature male with severe seminal alteration.
  • Male partner who is unable to produce sperm (azoospermia irreversible).
  • Male partner with radiotherapy, prior chemotherapy or other irreversible factor of male fertility.

  • Male couple carrying a genetic or hereditary disease known.
  • Women with Rh-sensitized Rh positive partner.

Women without a partner who choose single parent motherhood.

Women in a relationship who wish for pregnancy.


Most frequent causes for which need to resort to egg donation:

  • Early or secondary to surgery, chemotherapy and radiotherapy ovarian failure.
  • Genetic alterations endowment of gametes.
  • Serious hereditary genetic diseases and maternal.
  • It repeated previous failure of assisted reproduction by insufficient response to ovarian stimulation.
  • Repeated failure of embryo implantation.


The donation is a voluntary, anonymous and altruistic act. Donors (in the case of the donor women) must be healthy people aged between 18 and 35 years,  50 years in the case of man by law, although most clinics and sperm banks do not admit men above 35 years.

Before selecting a person as a donor the following data is collected:

  • A complete medical history of the donor and his family for any disease that is likely to be inherited.
  • The personal characteristics of the donor, blood type, height, weight, build, skin color, hair color, hair texture and eye color.

Legal Aspects

The regulatory legal framework governing Assisted Human Reproduction Techniques is constituted according to Law 14/2006, 26th May, referring to Assisted Reproduction Techniques. When gamete donors intervention occurs, it is especially relevant the Royal Decree-Law 9/2014, July 4th, due to the standards of donation in quality and safety.

Law 14/2006 on Assisted Human Reproduction Techniques defines the donation of gametes and pre-embryos, which are performed prior to signing of a free, formal and confidential contract, of which both parties agree on. In saying this, the data bank, personal records, and all activity within the centres, have an obligation to guarantee that privacy and identity of the donor in question remains strictly confidential.

For the recipient woman or couple, the choice of donor can only be made by the medical team applying the technique, and in no case at the request of the woman receptor or partner. Notwithstanding the foregoing, and, in any case, the medical team should seek the greatest phenotypic and immunological similarities to the receptor.

All donor candidates of genetic material must be more than 18 years of age, good mental and physical health, and with full consent to act. The psychophysical state of the donor must meet the requirements of a mandatory study protocol, including phenotypic and psychological characteristics, clinical conditions, along with laboratory tests necessary to demonstrate that the donor does not suffer from genetic, hereditary or transmissible infectious diseases that can be transmitted to the person's offspring.

Neither the parent woman nor the couple, (when formal consent given, prior and express consent to a specific fertilisation with the contribution of a donor or donors), may challenge the marriage affiliation of the born child, as a result of such fertilisation. Likewise, it will follow in cases of an unmarried male who had formally signed prior to the use of techniques consent.

So much as, the recipient woman and any child who could be born shall be entitled to obtain general information about the donor, however, that does not include their identity. Only exceptionally, under extraordinary circumstances involving a certain danger to the life or health of the child, or if applicable under criminal procedure laws, may reveal the identity of the donor, provided that such disclosure is necessary to avoid danger or obtain the proposed legal order. This revelation will be of restricted nature and not relay the donor´s identity, or indeed any of the previously established legal affiliation alteration.
