I'm not sure I understand you perfectly, but "sterile" means "unable to conceive children". So you could say, "She suffered sterility at an early age."
Another (less clinical) term is "barren". As in, "She has been barren all her life."
Sure. "Fertility problem" is an inverted positive. It's what people do when the more descriptive, simpler negative form of the same idea is deemed possibly uncomfortable to the sufferer.
Thus, "deaf" becomes "hearing impaired", "lame" becomes "disabled" becomes "differently abled", and "barren" becomes "a fertility problem".
Don't get me wrong -- I don't want to give the impre
I think the appropriate, non-euphemistic medical terms are "fertile" and "infertile/sterile." (There might be a technical difference between infertile and sterile.) "Barren" is not a medical term.
