Relationship between semen quality and seminal plasma components: alpha-glucosidase, fructose and citrate in infertile men compared with a normospermic population of Tunisian men.
The aim of this study was to evaluate the correlation between the secretory function of the male accessory glands and sperm parameters in normospermic controls and infertile patients. One hundred and fifty-nine men were investigated: they were composed of two groups: normospermic (n = 37) and infertile (n = 122) men with altered sperm characteristics. These infertile men were divided into the following groups: asthenozoospermia (n = 38), teratozoospermia (n = 40) and asthenoteratozoospermia (n = 44). The patients underwent semen analysis and measurements of fructose, neutral alpha-glucosidase and citric acid. The level of fructose was significantly decreased in asthenozoospermic and increased in asthenoteratozoospermic men. It was significantly correlated with semen volume, sperm count, motility and morphology. The seminal alpha-glucosidase levels were significantly correlated with semen volume and pH and citric acid was significantly correlated with pH. Thus, alpha-glucosidase and citric acid levels were associated with semen pH. The significant correlation between semen parameters, accessory glands and epididymal functions highlights the relationship between semen and normal genital tract function.
