The effects of Semen Parameters and age on Sperm Motility of Iranian men

Objective: Sperm motility is one of the most important factor in fertility of men. Because, it describes the ability of sperm to move properly through the female reproductive tract and reach the egg in order to fertilize it. Various factors, such as semen quality and other parameters are known to be effect on sperm motility. This study was designed to determine, how semen parameters and individuals age influence on sperm motility.Method: Samples were collected from 273 men undergoing evaluation and treatment for infertility in Infertility Treatment Center, ACECR branch of Qazvin, Qazvin, Iran. Semen analysis was performed according to World Health Organization (WHO) criteria. In this procedure we considered on determination of sample volume, sperm concentration, motility, normal morphology and liquefaction time. Results: In this analysis, our results showed, increasing in sperm count, sample volume and normal morphology increased sperm motility significantly. In contrast, increasing in liquefaction time and age decreased sperm motility significantly. Our statistical analysis demonstrated that sperm concentration and semen volume have the most and lowest effect on motility respectively.Conclusion: In our study, semen parameters tend to have an influence on sperm motility.
