Preparing to be flamed It's very sad when someone cannot conceive aged 40+ but to compared to someone in their 20s/30s isn't fair. Especially when the infertility is secondary It's very likely if the 40+ year old would have tried 5-15 years ago they wouldn't have problems conceiving. So many people try to deny the biological clock but sadly fertility does decline in people in their 40s. I understand people do get naturally pregnant in their 40s but stasticially it's rarer than people in their 30s and 20s.
