Keep in mind lots of things can affect his SA. The first one DH did was so low we were crushed but you remember what happened there. Horrible experience, he was nervous, they put him in a dirty bathroom with no sink, just a toilet, made him wait almost two hours even though he had an appointment. Second time, he did it again (just because I had a feeling something went wrong the first time) it was at a totally different place and his results were stellar.
Moral of the story, if the first time it doesn't go well, try again in a month or so. You'll lose $150 but it's valuable information.
