Clomid round 4 and hubby semen analysis...

Tomorrow starts clomid round 4... I really thought this past month was our month... AF was sneaky this time and completely changed her normal signs, and I thought that we were pregnant... Anyway, tomorrow I start round 4, and my hubby has finally decided to have the semen analysis done ( we go Thursday for that)... We know that I have PCOS, but we have never had him evaluated... We are both nervous not only about the appointment but also about what the results might be... Have any of you gone through he semen analysis with your partner? I am going with him thurs, but I just don't know what to expect...
