Transgressing created limits?

I must admit to being ambivalent about this development: New technique allows women to put fertility on hold." I can sympathize with married couples who struggle over infertility and desperately desire offspring. Yet is it really a good thing that, say, sixty-year-old women should be giving birth to children they may not live to see to adulthood? Are we in danger of transgressing a creational limitation? Have we thought carefully enough through the social implications of such a development? I doubt it.
