- Sperm motility is better in men who adhere to a Mediterranean diet (MD) that includes high consumption of olive oil, fruit, nuts, legumes, vegetables, and whole cereals; a moderate intake of fish, poultry, and wine; and low consumption of dairy products, red meat, processed meats, and sweets.
Why this matters
- Men's reproductive health is declining worldwide, raising serious concerns about human fertility.
- Researchers studied healthy, reproductive-age men (N=106; mean age, 24.7 [SD, ±4.7] years).
- They grouped participants into tertiles according to degree of MD adherence and used multivariable linear regression models to evaluate the relationship between adherence and sperm quality.
- Funding: International Nut and Dried Fruit Council.
- Men in the highest adherence tertile had 12.8% greater sperm motility (β nonstandardized coefficient=12.785; P=.037) after adjustment for age, energy consumption, and BMI.
- The study had a small sample size, was cross-sectional, and did not determine causality.
- Patients were healthy men; results may not apply to other groups.
