allmywhat thank and yes you are right that there is an exclusion list that includes the rare and experimental stuff- but I am still concerned, because the list of exclusions is only for now. And even now, it only means that the family of the deceased person need to give permission first before transplantation can be done.
Over time and as more research is published globally and as more rare and experimental transplantation techniques and scenarios become routine, then these ‘excluded’ organs (ie is still legally usable for transplant with permission from relatives etc) .. as science moves on you would expect these organs (ovaries, uterus etc) to be reclassified as routine transplants?
The proposed exclusion doesn’t mean ‘can’t be used’ on principle and isn’t a permanently stable category.
I think that’s what is missing here. There isn’t any permanent list of named cadaveric body parts that are on principle never to be made available for transplant from a dead person.
If you had such a list of ‘not to be transplanted from a dead body without consent from that person when they were alive’ ... that would not prevent any of us in our own will specifically leaving our ovaries and womb to our sister (or brother) or alternatively to anyone on the transplant list who needed them if we were to die suddenly and they needed to use them.
If people want to be a living donor of their own reproductive organs or embryos (like already now they can be) then fine that is with their consent. You don’t have to be dead to donate those things. (Though living people aren’t allowed to donate foetuses, so not sure why cadavers should have to.)
I don’t understand the inclusion of fetuses in here- this is not for research it’s for transplantation treatment.. ?? How is that going to work? All seems a bit like moving the window and no consideration of the rights of the child or mother to me. They have not mentioned any system of government oversight or committee oversight or whatever if a fetus is taken from a dead body with the relatives consent. Then what could happen next to it?
And so long as we have a GRC system in the UK I don’t know how you could be able to specify that either in life (if you give your own reproductive organs to a transplant list not a named person) or after your own death under this proposed new system (if you give your vagina plus reproductive organs) that your organs can only be transplanted into a female person rather than someone with a male body who identifies as female.
With various other forms of organ donation you can put conditions on who you want to receive your specific donation of that organ. Not sure why not with this new system. 
I have no issue with anyone having my heart, lungs, pancreas or whatever by the way and in principle I think presumed opt out is a good thing- just not for all organs and not on relatives’ permission.
