Abstract
ESKENAZI and co-authors, 140 Earl Warren Hall, School of Public Health, University of California, Berkeley, CA 94720-7360, USA, eskenazi@berkeley.edu, have found that antioxidant intake is associated with the quality of semen in healthy men.
Background
The aim of the study was to determine whether the intake of zinc, folate and antioxidant vitamins is associated with semen quality in healthy men.
Methodology
97 volunteers provided semen and a food-frequency questionnaire. Semen volume, sperm concentration, total sperm count, motility, progressive motility and total progressively motile sperm count (TPMS) were measured.
Results
A high intake of vitamin C was associated with higher sperm counts. High intake of vitamin E correlated with higher sperm motility. Higher intake of beta-carotene also correlated with higher sperm concentrations. There was no association between zinc and folate intake and sperm quality.
Conclusion
It appears that a high intake of antioxidant vitamins is associated with better sperm quality.
