In Spain it is possible for same sex female couples to undergo assisted reproduction treatment, thanks to comprehensive and open legislation. For this reason, many female couples come to URE Centro Gutenberg to have children. With artificial insemination, in vitro fertilisation and egg donation treatments the sperm shall always be from a sperm donor and shall guarantee anonymity as established by Spanish legislation. In Spain, it is important to keep in mind that the women must be married so that any child born thanks to assisted reproduction treatment is legally the offspring of both women. Legislation on this subject in other countries is diverse; thus, if your child is going to be born outside of Spain we recommend becoming very well-informed beforehand.
