Food Intake Among Women and Men in Fertility Treatment (Food&Fertility)

July 7, 2026 updated by: Ulrik Schiøler Kesmodel, Aalborg University Hospital

Food & Fertility - Does Food Intake Affect Your Fertility?

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.
