The UK Womb Transplant Research Team is fully aware and respectful of the 2010 Gender Equality Act that mandates equal care for transgender women, assuming technical feasibility.
I think we have to assume that they are talking about the Equality Act 2010.
They have clearly got some dodgy advice and their interpretation of the act is wrong, unless they think that they would be obliged to provide this treatment for any man who requested it.
They do go on to say
However it is abundantly clear from all recent experience and research that technical feasibility for a safe and successful operation for a transgender female, together with the possibility of sustaining a successful pregnancy, does not currently exist and that many years of detailed medical research will be required before this might become a viable and safe option.
