Correlations between heavy metal concentration 
and semen parameters: 
Correlations were done between serum concentra-
tion of heavy metals and semen parameters. A signifi-
cant correlation (p<0.05) was noticed between serum 
zinc and (age, time work, infertility duration, semen 
volume, liquefaction time, semen PH, immotile sperm, 
normal morphology and agglutination). The correlation 
was also significant (p<0.05) between serum lead and 
time of work, infertility duration, liquefaction time, 
semen PH, percentage of immotile sperm and normal 
morphology percentage.
Other correlations were done between semen con-
centrations of heavy metals with semen parameters. For

significant correlation (p<0.05) was documented be-
tween semen zinc and infertility duration, liquefaction 
time, PH and sperm progressive motility. On the other 
hand a significant correlation was recorded between 
lead semen concentration and age, time work, infertility 
duration, semen PH, progressive motility, immotile 
sperm percentage, normal sperm morphology and round 
cells number. These results were summarized in table 4.
