where:
• A long time interval, a long segment, cheesy material and antisperm antibodies are unfavorable findings.
number of favorable findings =
= SUM(points for all 5 parameters)
Interpretation:
• minimum number of favorable factors: 0
• maximum number of favorable factors: 5
• The chances of conception by the sexual partner increases as the number of favorable factors increase.
