Analysis of relationship between semen quality and sperm acrosin activity / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the activity of human sperm acrosin and semen parameters in male infertile patients and discuss the effect of sperm acrosin activity on semen quality.</p><p><b>METHODS</b>Activity of human sperm acrosin, PMN-elastase, fructose, alpha-glucosidase, zinc, acid phosphatase levels and HOST of 214 male infertile patients were detected. Semen analysis was performed using WLJY-9000 WeiLi colorful semen quality analyzer. There were 111 cases of normal activity of human sperm acrosin (48.2 - 218.7 microIU/10(6) sperm), 103 cases abnormal (< 48.2 microIU/10(6) sperm). Using the group of normal activity of sperm acrosin to be the control, semen parameters was analyzed and compared with those of the group of abnormal activity of sperm acrosin.</p><p><b>RESULTS</b>There were significant difference (P < 0.001) between the 2 groups (normal and abnormal) in the areas of sperm density, motile sperm rate, percentage of grade (a + b) sperm and HOST. There were also significant difference in PMN-elastase, fructose and alpha-glucosidase (P < 0.05). There was no difference among sperm volume, zinc and acid phosphatase (P > 0.05).</p><p><b>CONCLUSION</b>There was a strong correlation between the activity of human sperm sperm acrosin and semen quality. Activity of sperm acrosin is a reliable index of semen quality.</p>
