Abstract:
OBJECTIVETo explore the correlation between the biological characteristics of volunteer donors and sperm parameters.
METHODSSperm parameters were analyzed for 778 primary volunteer donors by CASA system with standard methods recommended by WHO including sperm concentration, motility rate, VCL, VSL, ALH, LIN, STR and BCF, and their biological characteristics were recorded.
RESULTSOf all the volunteer donors, students accounted for more than a third, 89.2 percent were under the age of 35 years, 71.6 percent between 166 and 175 cm in height, 91.7 percent of normal weight and 77.1 percent with college education. The median sperm concentration and motility rate were 107.00 x 10(6)/ml and 75 percent respectively. Age was weakly correlated with such semen indexes as concentration (r = 0.210, P = 0.000) , motility rate (r = 0.213, P = 0.000), volume (r = 0.165, P = 0.002), VAP (r = 0.259, P = 0.000), VSL (r = 0.281, P = 0.000), VCL (r = 0.190, P = 0.000), BCF (r = 0.243, P = 0.000) and LIN (r = 0.192, P = 0.000). The semen indexes of the 26-35 age group were a little better than those of the 20-25. Height showed no correlation to semen indexes. Education and occupation were somewhat related with other sperm parameters (P < 0.01) than ALH (P = 0.695/0.886).
CONCLUSIONAge, occupation and education bear some correlation with sperm parameters except ALH, while height has none with any of them.
