Primary Outcome Measures:
- Semen Quality as determined by the following parameters:
Semen volume [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
- Semen pH [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
- Leukocytes concentration [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
- Sperm cells concentration [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
- Motile sperm cell concentration [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
- Total motile sperm cells threshold [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
- Sperm cells morphology [ Time Frame: The same day as sevan evaluation according to the gold standard ] [ Designated as safety issue: No ]
Quantities assessment of semen quality as defined by:
Semen volume, semen pH, leukocytes concentration, sperm cells concentration, motile sperm cell concentration, total motile sperm cells threshold and sperm cells morphology
