OBJECTIVE 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. METHODS 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. RESULTS 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). CONCLUSIONS 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.

D013081	Sperm Motility	Movement characteristics of SPERMATOZOA in a fresh specimen. It is measured as the percentage of sperms that are moving, and as the percentage of sperms with productive flagellar motion such as rapid, linear, and forward progression.	Motilities, Sperm,Motility, Sperm,Sperm Motilities
D013094	Spermatozoa	Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
