The social evolution of the concept of "the family" and changes in attitudes towards homosexual couples have expanded the range of people permitted to gain access to assisted reproduction technologies, encouraging the creation of blended families. "Reception of Oocytes from Partner" (ROPA) is a treatment that permits female couples to become active participants in the reproductive process and have a biological connection to their child. This article reports a case of transnational shared motherhood, in which the Italian Supreme Court (Application no 19599, Supreme Court of Cassation, First Civil Chamber, 2016), dealt for the first time with a same-sex couple's request concerning the recognition of a legal child-relationship with a child conceived through in vitro fertilisation with ROPA. Although Italian law bans assisted reproduction technologies for same-sex couples, the Court acceded to the request of the couple on the basis of its evaluation of what was in the best interests of the child.
