The Food & Fertility study is a multicenter prospective cohort study which is planned to enroll a total of 4000 women and men between 2022 and 2024. The data collection will take place in four fertility clinics through a web-based food frequency questionnaire (FFQ). Data on sperm quality and pregnancy- and live birth rates will be obtained from medical records and national registers.
Worldwide infertility is highly prevalent and lifestyle factors, such as food intake, could have an essential role in the success of a fertility treatment. The literature is not consistent and adequate for recommendations to the increasing number of women and men of reproductive age who ask for lifestyle guidance. Therefore, the aims of the Food & Fertility study will be to investigate the association between food intake and semen quality, pregnancy- and live birth rates in women and men undergoing assisted reproductive technology (ART) treatment.
