Unless I misunderstand it, Rev\'s point is that in a world of finite resources, priority should be given to the most life threatening cases, then to the serious, then minor and so on, much like a hospital triage room.
In principle I don\'t see this as a problem, especially as the lesbians in question do not appear to have anything biologically the matter with them, and just 15 years ago would not have any legitimate expectation of having biological children.
What I do not agree with is the turn the discussion has taken regarding IVF and fertility treatment as a whole being not being publicly funded because it is not medically necessary.
There are actually two other considerations:
1. Where to draw the line at alleviating human suffering? I believe the NHS attempts to treat all cases, albeit not always in a timely way. Broken fingers aren\'t very serious and are cheap to treat, should the NHS start turning these people away? What about broken nails, or splinters? What about autism, which is not life threatening, or particularly subsceptible to favourable results, but expensive to treat? I think ideologically at least the NHS is taking the right tack in thinking that fertility falls within their mandate, without commenting about their overall success in more critical areas like heart surgery.
2. Who\'s going to pay for and encourage the next generation of IVF doctors if there is no government funding? With dropping fertility rates in the UK any responsible government with a long term view is going to be thinking of having at least a reasonable size cadre of experts on call for the current and future need. One of the problems with the NHS is that if any expensive procedure isn\'t funded by it, then progress in that area is usually stunted.
Consideration 2 is actually more of a problem with the NHS as a concept. Since so much money is poured into it, anything that is excluded becomes marginalised, which may not reflect the true desire or needs of the market. It distorts demand and supply by adding an intemediary in between.
There are alternative health systems out there that have their own problems, but don\'t have distorting economic effects. They do provide insurance for treatment in the event of infertility, but since there is nothing biologically wrong with the lesbians or single women who wish to be mums without the \"unneccesary\" step of intercourse, this would not apply.
In effect, the parents of the lesbians would have had to take out insurance against their children being gay and hence needing to resort to this sort of treatment. If the society as a whole agrees to this type of social insurance then the cost of this type of treatment can be spread out over many private insurers.
However, the slippery slope there is, do we pay for womb transplants to gay or single men once the science catches up?
I think eventually it boils down to cost, and if you\'ve got extra IVF doctors around you have to feed, as in case 2, opening it up to single women and lesbians may not be throwing away money, rather its retaining doctors. The needs of doctors, rather than patients, has probably more to do with this decision than anything.
