Assessment of the level of seminal zinc and fructose concentration in seminal plasma of Vietnamese infertile men

This study assessed the association between the fructose and zinc concentration and various seminal characteristics. Fructose and zinc in semen reflects the secretary function of seminal vesicles. These Tests may help in assessing the diagnosis and the management of male infertility. Gather seminal plasma of 180males with average age of 31.13,6years old. Use the specific complex ant to form a stable colored complex with fructose or zinc. The colour intensity in a determining wavelength is proportional to the amount of fructose or zinc present in the sample. Seminal fructose concentration was significantly lower in oligozoospermic group and the azoospermic group in comparison with normozoospermic group. There are also many significant differences in Zinc's concentration in semen when compared two in term of three groups, consist of the oligospermic, azospermic and normospermic group. Sperm DNA fragmentation index in-group with normozospermia correlated positively with seminal fructose (r=0.47, P<0.05) and negatively with seminal zinc (r=-0.56, P<0.05) concentrations. In group with oligozospermia found negative correlation (r=-0.24, P<0.05) between seminal fructose with sperm DNA fragmentation. In addition, there were 3 patients with Klinefelter syndrome in group with non-obtructive azoospermia with elevated seminal fructose concentration.
