Several years ago, before I was married or had even begun dating my husband-to-be, I was chatting with a reproductive endocrinologist about when I needed to worry about my fertility going into decline. I was about to turn 30. Should I be worried? And how many quality reproductive years did I have left?
She told me most women were fine at 30 or 35. At her clinic, she said, she rarely saw women with problems related to “advanced ovarian age” before they turned 37 or 38.
I was surprised, to say the least. Like so many women, I had heard ad nauseam about “getting pregnant after 35.”
Despite all the chatter, I was not actually clear on why 35 was an important cutoff. Was it because getting pregnant was more difficult after 35? Or staying pregnant became challenging after 35? Or was that the age when the risk of chromosomal abnormalities like Down’s syndrome rose dramatically?
It turns out that none of these reasons are correct. Because in fact there is no reason; age 35 is not actually a cliff. It is not even a sharp bend in the curve, a point at which birth rates go into a steep decline. Those sharp bends come later, after 37, and again after 40.
