I think it's really important to try very hard to separate the medical facts behind this debate from the social/political emotive baggage. I'd be interested in responses to these little hypothectical questions:
If women had evolved so that we had no menopause, what age would be considered 'too old' to be a good mother?
If men had a menopause - I mean an absolute cessation of sperm production, rather than the average fertility slump in levels - what would your opinion about fertility treatments for them be like?
(In the latter case, personally, I suspect fertility treatment would be less taboo, better funded, more widely available regardless of age).
I was interested to see that 12ylon you mentioned your fathers age as well as your mothers. It's seems pretty unusual whenever I find this topic being debated. The focus is very much on the age of the mother. I do see your point, and it's a fair one given your experience. However, as life expectancy steadily increases, and better treatments for the medical problems that go along with this improve, it will hopefully become less of an issue.
If IVF for older women is disallowed bcause of clear medical facts around failure of the pregnancy, or health damage to the mother (beyond the usual risks of pregnancy, which, let's face it, is already fraught with peril), then let's assess the argument on that basis.
I do feel though, that so often the argument comes from a place of societal and political prejudice; that a woman can be deemed to be past it, while a man can make babies at any time of life. It's problematic, to say the least, and for me it raises a whole bunch of issues and questions that go well beyond arguments about budgets and health.
I am behind these recommendations. Women are capable of conceiving naturally at this age - it is biologically possible. I also think it should be available sooner, and that postcode lotteries should be erased. There should be better counselling, and perhaps a drive to encourage younger women who know they wish to put energy into their careers first to freeze eggs; to plan their potential motherhood as a carefully considered part of their futures with as much validity and information behind that decision as behind their working life.
