🇪🇸 Fertility treatment in Spain

The legal framework

Access

Law 14/2006 lets any woman over 18 with full legal capacity use assisted reproduction with her written consent, independently of her marital status and sexual orientation. If she is married, her spouse’s consent is also required unless they are legally or de facto separated. Clinics must inform her of the risks of pregnancy at a clinically inadvisable age, but the law sets no fixed upper age limit.^[1]

Egg and sperm donation

Donation is a free, formal and confidential contract between donor and center. Donors must be over 18 and pass a mandatory screening protocol. Donation is anonymous: recipients and children born can obtain general information about the donor, but not identity, except in exceptional circumstances such as a real danger to the child’s life or health. The medical team, not the recipient, selects the donor and seeks the greatest phenotypic and immunological similarity.^[1]

Surrogacy

A contract for gestation by a woman who renounces maternity in favor of another person is null and void by law, with or without payment. The parentage of children born this way is determined by birth.^[1]

Egg freezing and embryo freezing

Egg freezing for fertility preservation is growing in Spain: according to the national registry, 65,805 eggs were vitrified for that purpose in 2023, up from 58,248 in 2022, and 1,284 embryo transfers used eggs from patients who had preserved fertility. The same release reports that 212 trans patients preserved fertility in 2023. Under Law 14/2006 the donation rules above also apply to surplus eggs or embryos donated to other people.^[2][1]

For how egg and embryo freezing work and how common they are in the US, see our guides on egg freezing and frozen vs. fresh embryo transfer.

National Activity Registry (Registro SEF), 2023

Registry figures describe national activity. They are not a measure of any single clinic’s results, and they are not directly comparable with US CDC clinic data, which use different definitions. See how to read IVF success rates.

Questions to ask a clinic in Spain
