Its easy for everyone - surgeons, the medical establishment and women to get caught up with the positives of such medical breakthroughs, and not consider the wider implications.
If it remains that only close relatives can ever be donors, it puts tremendous pressure on women within families that is often hiden from society.
If the donors are eventually going to be from a wider circle, that comes with additional social implications. Its going to be like surrogacy - the rich using poor womens bodies.
Maybe the solution will be donors after death, but im not sure thats as feasible as life saving donations. The transplant process is very complicated, and requires full time workers to coordinate. Who will do that?
Wombs can only be taken from women, and these women will be taking extreme risks for no personal benefit. It can only succeed if women are pressured to be kind, or are financially rewarded.
With respect to financial reward, the women wont be paid anything like the money they should. Infertile women will say the procedure is life saving, surgeons will be paid a fortune, hospitals and drug company will make lots too. The women who donates are womb that makes all of this possiblr should be paid the most, shouldnt she?
