Abstract:
Fructose is formed in the seminal vesicle under the
action of testosterone and is secreted along with the
vas deferens during each ejaculation, so fructose
is considered a biochemical agent that faithfully
reflects the function of these components. Fructose
concentrations in normal semen confirm the role of
testosterone and the function of normal seminal vesicles,
without the phenomenon of obstruction. Materials and
methods: the semen samples were obtained from 30
male partners of infertile couples who had consultation
at Genetic Counseling Centrer of Hanoi Medical
University Hospital, and the semen samples were
analysed for the seminogram parameters. Fructose
concentration was assessed using self-manufactured test
kit (according to the improved ROE method). Results
showed that the optimal solution concentration of
TCA was 10%; composite color composition included
2.5 ml of HCl 30% and 0.25 ml of resorcinol 0.1%;
repeatability was CV%=1.407% (<5%); intermediate
precision was CV%=2.032% (<5%); correctness was
tex=0.906<tt =2.262. In conclusion, the manufacturing
procedure of the test kit for determination of fructose
concentration in seminal fluid was successfully verified
