The attitude about the role of sperm and infertility used to be: sperm quality makes no difference. But numerous studies are showing strong connections between food, sperm and infertility. For example, a 2013 study from the Harvard School of Public Health concluded that carotenoids (pigments in plant-based foods that act as antioxidants) may positively impact semen quality. Here’s a list of fertility-boosting food for men and a few foods that he should avoid.
About 1/2 cup (60 g) per day improves sperm motility and strength, notes a 2012 University of California study.
“For men, drinking coffee increases sperm motility, a key factor in successful insemination,” notes Bentov. “If a man’s sperm isn’t moving fast, we ask him to drink coffee before sex.”
In a 2008 Harvard School of Public Health study, higher levels of soy intake were linked to a lower sperm concentration.
Avoid saturated fats
Don’t eat saturated fat found in butter, poultry skin and fatty cuts of meat. A 2012 Danish study found that eating high amounts of saturated fats lowered sperm count.
