[Automatic detection and clinical application of semen biochemical markers]

Human seminal plasma is rich in potential biological markers for male infertility and male reproductive system diseases, which have an application value in the diagnosis and treatment of male infertility. The methods for the detection of semen biochemical markers have been developed from the manual, semi-automatic to the present automatic means. The automatic detection of semen biochemical markers is known for its advantages of simple reagent composition and small amount of reagents for each test, simple setting of parameters, whole automatic procedure with few errors, short detection time contributive to batch detection and reduction of manpower cost, simple calibration and quality control procedure to ensure accurate and reliable results, output of results in the order of the samples in favor of clinical diagnosis and treatment, and open reagents applicable to various automatic biochemistry analyzers. At present, the automatic method is applied in the detection of such semen biochemical markers as seminal plasma total and neutral alpha-glucosidase, acid phosphatase, fructose, γ-glutamyl transpeptidase, zinc, citric acid, uric acid, superoxide dismutase and carnitine, sperm acrosin and lactate dehydrogenase C4, and semen free elastase, which can be used to evaluate the secretory functions of the epididymis, seminal vesicle and prostate, sperm acrosome and energy metabolism function, seminal plasma antioxidative function, and infection or silent infection in the male genital tract.
