I’d be interested in additional factors, especially BMI (even as flawed as that index might be).
Insulin resistance and fertility:

Few more notes:
- Insulin resistance is directly correlated with fertility status...but not necessarily BMI as some skinny women also have insulin issues.
- But on the topic of BMI, obesity is often cited as one of the main reasons why maternal mortality (during childbirth) is higher in our country than in other developed ones.
