This article considers three “unanswered questions” raised by R. (McConnell) v Registrar General for England and Wales (AIRE Centre Intervening) [2020] EWCA Civ. 559, which held that a trans man (with a Gender Recognition Certificate) who gave birth must be registered as “mother” on his child’s birth certificate. This article considers these questions to clearly situate McConnell within the context of the UK’s legal regimes concerning access to fertility treatment, gender recognition and legal parenthood in cases involving assisted reproduction. The article argues that clearly establishing the current legal position will provide the proper context to facilitate any subsequent legal reforms.
