There are no other known cases of a pregnant transgender person in the UK.

But the BMA is urging doctors to avoid offending transgender people in a bid to “celebrate diversity”, the Mail on Sunday says.

“However, there are some intersex men and trans men who may get pregnant.

“We can include intersex men and trans men who may get pregnant by saying ‘pregnant people’ instead of ‘expectant mothers’.”

Tory MP Philip Davies said it was “completely ridiculous”.

He added: “If you can’t call a pregnant woman an expectant mother, then what is the world coming to?”

The BMA has insisted: "This is a guide for BMA staff and representatives aimed at promoting an inclusive workplace at the BMA.

"It is not workplace guidance for doctors, which is clear from the fact it does not refer to patients."
