Pre-infertile - the worried well

I am now seeing an increasing number of couples who do not have any medical problem, but are worried about their fertility. I call these couples "pre-infertile". This is not a word described in a medical textbook, but I think it describes them well. They are worried that they may have problems conceiving, which is why they are seeking medical advise . These are the "worried well" - they don't have an illness, but are concerned that they might. All they really need is an explanation about the fact that Nature takes time to make a baby, and some reassurance; and for most, this is enough to help them promptly get pregnant on their own ! Others will want tests done to confirm that all is well, and even though I don't feel this is an appropriate use of medical testing, sometimes it's worth it for the peace of mind it gives them !
