Spanish laws allow gamete donation, both sperm and eggs, in exchange of a certain amount of money that varies depending on the clinic and on the type of gametes donated (sperm or eggs).

This donation is completely anonymous, and while people born via donations can theoretically access to their records with a minimum of their donor’s data – such as age, height and eye color-, in many occasions they are answered with silence or an explanation that their records were destroyed.

This situation, however, crashes with the 39th article of the Spanish Constitution, which states that “The law will make possible the investigation of paternity”.
