I don't find it insulting, but I am concerned about the apportioning of medical resources to those who are in greatest need.

I'd hate to think that couples who are going through a long and possibly distressing journey to conceive via IVF might miss out on specialist care and attention when they need it because others are using it as a matter of convenience or choice, kwim?

I'm also concerned because when there is greater need, a demand-driven market tends to drive up prices, so again, a negative side affect could be an increase in the costs associated with IVF treatment for those couples for whom this is their only option.
