Diet and semen quality in healthy males from the population of the Lower Silesia region in Poland (the androls study)

Abstract

Background Numerous studies have shown the associations between different dietary patterns and semen quality in a male population. There is no evidence on the relationship between dietary intake and markers of male fertility potential. The aim of this study was to investigate the relationship between dietary nutrients intake and semen quality parameters among healthy men from Lower Silesia (a region of Poland). Methods We enrolled 177 healthy young men aged 18-35 years from a genetically homogenous population of Lower Silesia (a region of Poland). Those who responded to the invitations were asked to complete the questionnaires covering: medical history and nutritional habits (last 5-day recall diary). The semen samples were analyzed with use of the Sperm Class Analyser. Results The results showed a statistically significant positive correlation between the intake of saturated, monounsaturated fatty acids and immotility. The results also demonstrated a statistically significant positive correlation between energy derived from fat and immotility and rapid (a) and slow (b) progressive motility. As well, a statistically negative correlation between the energy value of the diet and sperm concentration, energy derived from the consumption of carbohydrates and semen volume, consistency and the energy derived from the consumption of fat and sperm consistency and immotility was shown. Conclusion Based on our studies we concluded that further research is needed to confirm these findings and extend these results to other populations.
