Some fertility problems go unnoticed for a decade. I suggest to my younger (25-29) female friends to have their egg reserve estimated, even if they at that point are not thinking about ever having children. This is because the original issue can be upstream of the couple: a parent who had early menopause, or low ovarian reserve, may pass similar characteristics down to their female progeny.(Source: conversations with IVF team)

hmm... yeah, this would be an interesting biomarker for those in their twenties. It could be valuable later in life.
I was surprised to learn women are born with 1-2 million eggs. By 20 years old, they only have 200k-300k left. They lose more every year.
