Preservation of Sperm Motility With Modrate Intensity Static Magnetic Fields

Male infertility include 40to50% of all infertility cases. sperm motility is a one of the important parameters in male fertility.The goal of this study was to preserve sperm motility with modrate intensity of static magnetic field during the sperm are useing for experiment .Materials and Methods: After initial examination,the semen sample were collected from normospermic men (n=90), and were allowed to liquefy for 15-30 min. Each sample was divided into two subsamples that were exposed (‘‘treated’’) or not(‘‘control’’) during, 5 hr to a uniform static magnetic field at the center of permanent magnetic. The content of sperm motility was determined by CASA (computer assisted sperm analysis). Data analysis was performed using SPSS (version 16) and paired t test. The p-value <0.05 is considered significant. Result: Sperm motility was significantly increased under the influence of static magnetic field while the motility percentage of sham group decreased the motility .The sperm kinematic parameters (VSL, VCL, VAP) were observed retain in the group that was exposed to modrate intensity static magnetic field after 5hr exposed. Conclusion: The static magnetic field could have affected human sperm motility. The result of this experiment showed the MF at (modrate intensity ) after 5hr retained sperm motility .However, sperm velocity was significantly affected by exposure of sperm to MF. The static magnetic field can affect the human sperm motility by increasing the percentage of motile spermatozoa and the correlated kinematic parameters, but these effects depend on the applied intensity and time of the applied magnetic field
