Well first up, the issue of whether or not Brad and Angelina's twins were naturally conceived or not is obviously irrelevant! (why all the debate on this?!) - they being merely a catalyst for raising the topic of whether or not IVF treatment specifically for twins, in a healthy couple is ethical or not.
Personally (and this will always be a very subjective topic), I am always very leery of medical procedures being performed unecessarily in healthy individuals (not just IVF). I think there is are definite ethical issues in exposing an individual to the associated risks (low though they may be, granted) of a purely voluntary and 'to order' medical procedure when they have a healthy natural alternative. Is the treating physician truly acting in their patient's best medical interests? Particularly in this debate, where the 'voluntary' pregnancies in question are twin pregnancies with the statistically markedly higher associated risks.
And of course the other major issue for me is one of resourses. Certainly I beleive that in the allocation of fertility treatment resources, 'voluntary' couples should be at the end of the queue at the very least, and no public health insurance should cover any of it.
I think we need to be very aware also, of where this could potentially lead, and what is fueling the access to this 'voluntary' fertility (including 'to order' twins). In 2007 I travelled to the USA to access IVF as a surrogate, for friends of mine who had tried unsuccessfully to conceive for approximately eight years. I can certainly vouch for the fact that the large fertility clinics there, are all about commercialism - they are absolute 'baby making' production lines (it quite took my breath away, and was somewhat distasteful and offputting from my perspective). Would we really want our fertility clinics in Australia to take on such an industrial commercial edge: profit making, 'user pays', 'to order' pregnancies? Hmmm.....
Leading on from this is the issue of how much 'control' we should ethically be able to access over our pregnancies - where does the buck stop. If we can have a twin pregnancy 'to order', what about gender, or (as genetic sciences scurry along) specific physical characteristics, or, or, or............it certainly a line in the sand that we need to think about. (Don't get me wrong folks, I'm absolutely pro genetic technologies, where there are genuine health or fertility issues to address).
Absolutely finally (sorry for this being so long!!), having undergone IVF treatment, I think you'd have to be mad to access it for no good reason - it's lengthy, incredibly invasive, and most unpleasant.
By the way - I had twins (the embyos weren't fabulous, so it was judged prudent to transer two embryos, and they obviously decided they were there to stay anyway!!).
