Fantastic work! This is clearly the best article I've read this year! It has wonderfully practical information that is immediately clinically useful. It offers either science or consensus to support useful recommendations. Further it confirms much of the practice that I've held over years, yet dispels other (fertility) practices that had been passed down over the years without support. I'd love to see other committee opinions on other topics that we see as frequently as we do fertility concerns. Thanks, this helps greatly.

Are there data that support comparing the size of the effects on female infertility of the factors in Table 1 (e.g., smoking, drinking) to that of women's age (e.g., 37 or older)?  That is, is older age a larger risk factor for women's infertility than the modifiable factors in Table 1?  Thank you!

This article was very well-written and helpful for practicing clinicians. I believe there is an error in Table 1. The authors cite the Clark paper stating that women with a BMI < 19 take 4-fold longer to conceive, however the Clark paper only studied women with obesity. The Clark paper does not even discuss women with low BMIs or who are underweight in the introduction/discussion. As, such I believe this citation is inaccurate. If they meant to cite a different paper, I think that should be updated, so readers can access the primary data behind the reported statistic.
