The aim of the present study was to assess the relationships between the stress which results from the work and human semen quality.

The work stress which was studied includes two types; quality stress (easy and moderate to hard performing work / day) and quantity stress (number of hours performing work / day.

Results are elaborated by using independent t-test statistical method.

From fifty two men which has an easy and moderate work and forty eight men with daily hard job, we determined significant negative (p < 0.05) influence of stress on sperm concentration, sperm grade activity, percentage of sperm motility, and percentage of sperm viability.

Quantity stress showed that a men with 7-10 hrs performing job/day has a significant (p < 0.05) lower; sperm concentration, sperm grade activity, percentage of sperm motility, and percentage of sperm viability compare with 4-6 hrs performing job / daily.

No significant differences were recorded between quality and quantity stress in which means that both types of stress has the same effect on semen quality.
