perhaps it should depend on why they need it - if theres no medical reason preventing pregnancy, and its just because of bad luck and timing etc and they want to hurry it along because they are getting older, then no, but if their infertility is down to a medical problem and they have been trying for years, then yes, why not?
it would be treating the symptoms of a medical problem...
i have PCOs and have always assumed i would have kids one day but knew id likely need IVF...and ive always been aware of the notion that i may never have them, however now, at 41, i cant say i am all that bothered about it. the only worry i have is what if i regret it once its too late, but thats not really a very good reason to have a child, is it?
get one in quick before its too late, 'just in case'...
perhaps there should be some kind of 'help' for those, where they pay half or something
