[Correlation of seminal plasma biochemical indexes with routine semen parameters in sperm donors].

OBJECTIVE: To investigate the relationship of seminal plasma biochemical indexes with routine semen parameters and that between seminal plasma biochemical indexes. METHODS: Using the automatic biochemical analyzer, we measured the contents of neutral α-glucosidase (NAG), fructose hexokinase (Fru) , citric acid (CA), acid phosphatase (ACP), (zinc) Zn, uric acid (UA), lactase dehydrogenase (LDH) and α-hydroxybutyrate dehydrogenase (α-HBDH) in the seminal plasma of 84 sperm donors in the Human Sperm Bank of Hebei Province. We analyzed the correlation between these indexes and that between routine semen parameters and these indexes. RESULTS: Sperm concentration and total sperm count were correlated positively with the contents of seminal plasma NAG, ACP, Zn, CA, LDH and α-HBDH (P<0.05) but negatively with Fru (P<0.05), the percentage of progressively motile sperm positively with seminal plasma Zn (P<0.05), and CA positively with NAG, Zn, LDH, α-HBDH and ACP (P<0.01) but negatively with Fru (P<0.01), NAG positively with Zn, LDH, α-HBDH and ACP (P<0.05) but Fru negatively with ACP (P<0.01), Zn positively with LDH, α-HBDH and ACP (P<0.01), and LDH positively with α-HBDH and ACP (P<0.01) but UA negatively with ACP (P<0.05). CONCLUSIONS: Biochemical indexes in the seminal plasma of healthy men are not only closely related to each other, but also to some routine semen parameters.
