I have no maternal instinct so I don't fully appreciate how strong the urge is to have a family.
I think that if you can't have kids and there is nothing that medical science can do (unblock tubes etc) then they should consider adopting.
IVF is expensive and it must be horrendous undergoing repeated treatments and still having no child at the end of it. I don't know what the success rate is.
Quite so, there is no shortage of people (quite the opposite in fact - over population is the greatest threat to humanity and sees alleged "climate change" pale into insignificance). No public money should be spent enabling people who cannot have children naturally to do so. It's tough for couples who cannot have children. But hey-ho life's not always fair and they should view their plight as doing their bit towards helping cure over population.
