A transgender man who does not want to be described as the “mother” of his baby on a birth certificate has lost his legal fight to be recognised as the father.

Freddy McConnell, a multimedia journalist who works for The Guardian, wanted to be registered as father or parent of his child.

A judge on Wednesday ruled against him after analysing argument at a High Court trial in London.

"There is a material difference between a person's gender and their status as a parent," said Sir Andrew McFarlane, president of the Family Division of the High Court, in a ruling.

"Being a 'mother', whilst hitherto always associated with being female, is the status afforded to a person who undergoes the physical and biological process of carrying a pregnancy and giving birth.

"It is now medically and legally possible for an individual, whose gender is recognised in law as male, to become pregnant and give birth to their child.

"Whilst that person's gender is 'male', their parental status, which derives from their biological role in giving birth, is that of 'mother'."

A lawyer who represented Mr McConnell said an appeal was being considered.

"As a firm that champions equality, we are of course disappointed at the judgment and it highlights how the law is slow to keep up to modern society," said Karen Holden, founder of A City Law Firm.

"Freddy is legally a man and his legal papers display the same. In the UK he has the right to change his gender on his own birth certificate so why not his child's? Surely if you are going to move with modern times, the law has to finish the journey it has started.

"Equality shouldn't have to come at a price, but this case has taken three years, hours of work and manpower, public attention and yet the courts still failed to help this family set out its actual family structure correctly in terms of its legal status.

"A birth certificate will stay with a child for life and it will be factually and legally inaccurate under current rules.

"Freddy is considering whether he wishes to appeal, and we have no instructions on that at present.

"We hope though others will pick up the chalice as well and look to bring UK law in line with other more progressive countries."

Mr McConnell, 32, who had a child using a sperm donor, claims in the documentary Seahorse: The Dad Who Gave Birth that pregnancy would be taken more seriously if more men gave birth.

In the film, which portrays his fatherhood journey over three years, he says: “If all men got pregnant then pregnancy would be taken so much more seriously and talked about.”

He adds: “F***, it’s f***ing awful. If men had to go through this all the time you would never hear the end of it.”

Lawyers said the child would be the first person born in England and Wales not to legally have a mother if Mr McConnell won his case.

They say other transgender men have given birth but been registered on birth certificates as mothers.

Sir Andrew heard how Mr McConnell is a single parent who was born a woman but now lives as a man after surgery.
