Infertility Statistics - 1 in 6 couples

The ladies in our newly planted church had the first Ladies’ Night Out. We carpooled and I was on a car with 4 other ladies. It was interesting that we represented the latter 20+ years of the age and fertility spectrum:
50+ - 3 adult/college-age children
46yo - 2 high school children
40+yo - 17, 12, 10yo children
38 yo - 3yo twins
40yo - 0 (Yes, this is me.)

Recently, I’ve been catching myself seeing crowds, groups and friends from the statistical viewpoint of the of 1 in 6 couples being infertile. The above is the most recent.

I have thought through other “sample populations” I am/was a part of:
- my friends way back from high school…1/7
- my friends back in Boise…1/30 (with 4/30 having miscarriage and short-term IF and all have moved on to motherhood)
- my church friends in Boise…1/6
- my church friends in Austin…?
Why am I consistently the “1″ in these different groups, I complain. But why do I expect differently since I have filled the “quota”? Am just glad though that most of them have been sensitive of our infertility.

Have you looked at the world from this standpoint also? Or is it just me?
