Summary

This study looks at whether drinking a daily serving of gazpacho, a cold tomato-based soup, can improve semen quality in men with low sperm counts or poor sperm movement. Eighty men will follow a Mediterranean diet for 12 weeks, with half also drinking gazpacho each day. Researchers will measure changes in sperm health and oxidative stress to see if this simple food addition helps.
