Sir Andrew McFarlane has called for a review of the UK fertility laws after a transgender man (known only as TT) fell pregnant 10 days after completing his legal transition from being a woman following fertility treatment. A civil claim was brought against the NHS for their involvement in the treatment.

TT has taken the case to the high court, seeking to be registered on the child's birth certificate as the Father, with no Mother being named.

Currently under UK law, fertility treatment is only available to women and Sir Andrew McFarlane has suggested the legislation governing this, the Human Fertilisation and Embryo Authority Act 2008 needs to be reviewed and updated, raising concerns that TT was treated and given fertility treatment despite the clinic regarding him as a man.
