Consuming too much ultra-processed food can lower men’s fertility, affecting embryonic development, a new study suggests.
Researchers at Erasmus University Medical Center investigated the combined impact of mothers’ and fathers’ ultra-processed intake on pregnancy. They published their findings in the National Library of Medicine on May 1, 2026.
The researchers followed about 650 males and 830 female partners, tracking their routine diets before and after conception. Ultra-processed foods made up about 25% of men’s diets and 22% of women’s. The women also underwent ultrasound scans to measure embryonic development.Â

The results: In males, higher intake of ultra-processed foods was associated with subfertility and a longer time to pregnancy, possibly because sperm are especially sensitive to diet, according to the researchers. However, they noted that further research is needed to confirm the results and understand the underlying biology.
