• Percentile “5” to determine lower cutoff limits
• Strict (Kruger) morphology
• Single specimen per individual
Method
• Recent fathers (known TTP)
• Limited geographic location

23. Semen analysis alone should not be used
to counseling or treatment indication
l Semen characteristics that
discriminate fertile from infertile men
not well defined
l Biological variability
l Not account for sperm dysfunctions
