Resumen. España es el primer país europeo en número de ciclos de reproducción asistida y el tercero a escala mundial detrás de Estados Unidos y Japón. En cuanto al tipo de tratamiento específico, ocupa el primer lugar en Europa en donación de ovocitos. Sin embargo, pese a la potencialidad que representa España en la industria reproductiva y, especialmente, en la donación de gametos, apenas se conoce la versión de los/as donantes, las familias receptoras y la descendencia concebida a través de donación reproductiva. El objetivo de este texto es revisar y contrastar la escasa bibliografía existente en España sobre los actores protagonistas de un fenómeno cuyo volumen alcanza ya cifras llamativas, con la bibliografía internacional mucho más abundante. Palabras clave: Reproducción asistida con donantes; donantes de gametos; gestación subrogada; descendencia por donación; anonimato/no anonimato [en] The intervention of «third parties» in parenthood: perspective of donors, families and offspring. The state of the literature Abstract. Spain ranks first among European countries in terms of the number of cycles of assisted reproductive techniques and third worldwide after the United States and Japan. Regarding the specific type of treatment, it holds the first place in Europe in terms of oocyte donation. However, despite the potential that Spain represents in the reproductive industry and especially in the donation of gametes, the viewpoints of the donors, the recipient families and the offspring are barely known. The objective of this article is to review the scarce literature existing in Spain on the protagonists of a phenomenon whose volume has reached remarkable figures already, and contrast it with the international body of literature, which is much more extensive.
