That’s an important point. And then there’s the woman’s general health and health history.
I think there would be less experience of infertility if women learned fertility awareness and were taught the health practices, including diet, that would give them a better chance of conceiving.
I read that, of all the cases of couples struggling to conceive, one-third are about the woman’s infertility, one-third the man’s infertility, and one-third both or undetermined.
Before fertility clinics existed, some couples who married young did not conceive until they were much older. Sometimes life happens when least expected.
