The surgeons behind the UK's first successful womb transplant have ruled out performing the same procedure for transgender patients.
Professor Richard Smith and Isabel Quiroga, who led the groundbreaking operation, have warned that their research is not yet ready for trans patients.
The medical team have stressed that their work focuses specifically on helping women born without a womb, or those whose wombs cannot support reproduction.
Grace Davidson, 36, and her husband Angus, 37, welcomed their daughter Amy Isabel earlier this year following the landmark procedure.

Grace, who was born without a womb, received the transplant from her sister Amy Purdie.
The successful operation has opened the possibility that thousands more women could benefit from this medical breakthrough.
Professor Smith said: "It's really important to be clear about what we're trying to do, which is relief of suffering for women who have got no womb, or they've got a womb which is incapable of reproduction."
He further emphasised that "the whole project is about the creation of babies" for women with these specific medical conditions.
But their focus remains on addressing these needs - rather than expanding to transgender patients.

Quiroga said: "The only function of a uterus is to gestate - and the uterus doesn't make any hormones, it doesn't do anything. It only gives the capacity of a woman to carry her own child."
She also warned against transplants for psychological reasons, explaining: "The risks in the long term with immunosuppression and everything that entails is quite great."
Professor Smith added: "We have a lot of supporting structures in a female pelvis - where are you going to hook a uterus when we stitch one in a male pelvis?"
Research also indicates that women with surgically created "neo-vaginas" tend to experience miscarriages.
He believes womb transplants for transgender patients are "10 to 20 years away at least" and warned against "renegade" surgeons seeking to be "heroes".

Professor Smith's charity Womb Transplant UK has received permission to conduct 15 womb transplants in total.
This includes five from living donors and 10 from deceased donors, with four more living donors and seven more deceased donor procedures still to be performed.
The breakthrough could potentially benefit thousands of women across the UK.
Around 15,000 women have Davidson's MRKH syndrome, while many others require womb removal due to conditions such as endometriosis or cancer.
