Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this prospective cohort study is to learn about the overall and seasonal prevalence of vitamin D insufficiency and its determinants in a population of women with infertility who will go through in vitro fertilization in Sweden. The main questions it aims to answer are:

* What is the prevalence of vitamin D insufficiency?
* What are the determinants of this insufficiency? Participants will be asked to complete a questionnaire validated for dietary assessment of vitamin D intake and sun exposure habits and they will leave a blood sample for measurement of 25(OH)D concentration.

Researchers will compare the in vitro fertilization outcomes between women with vitamin D insufficiency and sufficiency to see if there is any difference.
