Frequently asked questions about sperm donation

How does semen donation work?

The donor comes voluntarily to the semen bank where he will be extensively informed and, according to the prevailing legislation, he will undergo series of tests with the aim of evaluating his physical and psychological health. The risk of transmitting some disease or known genetic defect will also be ruled out.

Is semen donation financially rewarded?

No, semen donation, similar to the donation of all biological products, is voluntary and altruistic, although the law foresees compensation for displacement and the time spent.

Who can be a donor?

Any male from 18 to 35 years of age without known diseases and without a family history of genetically transmittable diseases may be a donor. The results of a physical exploration, analytical tests -indicated in the legislation- and a seminal quality study have to be totally normal.

Once the donor has been selected, seried donations will be collected over several months and cryopreserved for later use in assisted reproduction techniques. Six months after the last donation, samples may be considered habile, as long as all the analytical tests repeated in this second phase are totally normal.

How is an adequate donor selected?

The donor selection for a determined patient is made by the bank itself. The process is based on using those donor samples which have the maximum compatibility with the receptor couple, at both an external appearance level (height, race, eye color, etc.) and from an analytical, blood group and Rh compatibility point of view.

Is there a limitation in the use of semen from the same donor?

The law establishes that the same donor may generate a maximum of six pregnancies (Law 14/2006). When this number is achieved, the bank must destroy the remaining samples from this donor.

Is it possible to know the identity of the donor?

In principle, no, it is not. The Law establishes that the identity of the donor must remain protected.
Under exceptional circumstances and legal control and judicial authorization, the identity of the donor may be known if the life or health of the child were in danger. In these cases the revelation of the identity does not, in any way, imply legal determination of the filiation.

Where are the data’s donors saved?

The donor’s personal information is under the strictest and most secret custody of the center’s databank. It is encrypted in the National Registry of Gamete and Prembryo Donors, which has the data of all the centers and departments with administrative authorization, aggregated by the autonomous communities and together in a single central national database which is administered by the Ministry of Health and Consumption.
