The man, who is in his thirties, gave birth last year, according to the Beaumont Society transgender support group.
The Society's Joanna Darrell said the man had approached the group asking for advice about having a baby.
She said: 'We had a general inquiry to the Beaumont Society.
'The society, all it does is provide information and acts as an information hub for people to find data about specific things, and we are able to refer them to more specialist organisations.
She added: 'We sometimes get people coming back to say thanks for our help. He got back in touch and said he had had the baby.'
