Fructose and zinc in semen reflect the secretory function of seminal vesicles. These tests may help in assessing the diagnosis and the management of male infertility. Seminal plasma was gathered from 180 males who averaged ± 3,6 in age. A specific complexant was used to form a stable coloured complex with fructose or zinc. The colour intensity of the complex in a determining wavelength is proportional to the amount of fructose or zinc present in the sample. The study found that seminal fructose concentration was significantly lower in the oligozoospermic group and the azoospermic group in comparison to the with normozoospermic group. There were also many significant differences in zinc’s concentration in semen when two of three groups were compared with one another. In conclusion, the role of seminal fructose concentration lie not only in the assessing seminal vesicle dysfunction, but also, in conjunction with other seminal properties could give a useful indication of male reproductive function, whilst seminal zinc concentration might not be most appropriate for the assessment of male reproductive dysfunction.

INTRODUCTION As many reasons cause male infertility, it is essential to identify appropriate methods to diagnose the underlying cause many tests have been applied previously, such as semen analysis, genetic tests and hormone methods. Recently, some of these biochemical markers zinc and fructose, are like increasingly recognized as important for Corresponding author: Nguyen Thi Trang, .
