It is mainly reflected by the proportion of forward motile sperm, which is one of the most important factors to judge male fertility. The sperm quality of men in Sichuan area was analyzed, and the influence of semen parameters and age on sperm motility and the effect of age on semen parameters were discussed. Method: According to the semen examination results of 18,200 male volunteers recruited from January 2018 to December 2021, the effects of age, semen volume, sperm concentration and sperm morphology on sperm motility were analyzed. effect on sperm quality. Divided into 5 age groups to analyze the effect of age on sperm quality. Result: The results manifested that semen volume, sperm concentration and normal morphology ratio showed a positive correlation with sperm motility, while there was a negative correlation between age and sperm motility, and sperm concentration had the greatest impact on sperm motility. With the increase of age, especially after the age of 40, the parameters of the semen decreased significantly. Conclusion: Semen parameters have an effect on sperm motility. The increase of age makes the sperm quality of elderly men decline, and the male reproductive time should not be too late.Read More
