Surrogacy should be banned worldwide as it is the commodification of children.
And no, the “you don’t know what it’s like….” Argument doesn’t hold water. Just because something can be done, doesn’t mean that it should. Sometimes people can’t have children, and as sad as that is that is life. Doesn’t give them the right to exploit another person, least of all the child they’re buying, in order to fulfil that desire.
In terms of IVF, no, I don’t think that it should be available on the NHS. The NHS is A, about saving lives, not creating new ones. Added t which, the success rate of IVF is so low that at least three rounds are required to have even a remote possibility of success. Several medical treatments are not funded by the NHS or even suggested due to the low success rate, this is no different.
Also there should be an upper limit. Women go through the menopause for a reason. Once you are no longer able to conceive children naturally there is no way that this should be enabled by medical intervention. FWIW I think that men who father children into their 50’s and beyond are equally selfish, but for some reason that is biologically possible, and short of giving every 45 year old the snip is impossible to police.
