We thought artificial insemination success was a genetic lottery. It turns out it depended on your shopping list

A Spanish study links Mediterranean-style eating with better artificial insemination outcomes in infertile women.

Women with healthier diets were more likely to have a Lactobacillus-rich vaginal microbiome, which is associated with successful pregnancy.

Poorer diets were associated with Gardnerella vaginalis dominance and treatment failure.

The findings suggest diet may be a practical, noninvasive way to improve fertility treatment success by influencing the vaginal ecosystem.
