Jason- these are interesting reflections on an exciting topic. I am sure our understanding of the relationship between Vitamin D and reproduction will evolve further in the next months and years. Do you currently check Vitamin D levels routinely on all (new) patients?

Thank you Jason for this original and insightful article! Hopefully, our knowledge about this interesting issue will evolve progressively.

Thanks to both Drs. Molina and Quaas for their comments. The vitamin D deficiency epidemic in the US is certainly complex given challenges with measurements and definitions. At present, given easy assessment (blood draw) and easy treatment (over the counter supplementation or more time at the beach) I do assess Vitamin D with new patient intake. There is some evidence to show that this may be impactful on reproduction (from the oocyte or the uterus, perhaps less clear) and I think the harm of intervention is very minimal with standard oral supplementation.
