Can Tomato Consumption Improve Sperm Quality?
In a randomized, placebo-controlled study, British researchers investigated the effects of lycopene on sperm, a red pigment found in tomatoes, watermelons, pink grapefruit and other red fruits and vegetables.
The scientists divided 56 men between the ages of 19 and 30 into two groups. For 12 weeks, one group took one tablet daily containing 14 mg lactolycopene, a combination of whey protein and lycopene, which facilitates the uptake of lycopene. The other group took a similar placebo. The men had blood and sperm tests at the beginning and at the end of the study.
"We conducted a small study identifying a compound in vegetables and fruits that improves sperm quality," said lead author Elizabeth A. Williams, a lecturer at the University of Sheffield. "But I would advise men to generally eat healthily. Probably other nutrients are also beneficial. "
