LisaL, my husband had the same thing - although his is for medical reasons. Once we got back the count, DH was booked in for a surgical sperm collection. There are two types TESA and ??? (sorry cant' remember the other one).. They look in the tubes and in the area where sperm is produced. The operation is only about 1hr (from the time they wheel them in to the time they wheel them out). There is a scientist in the room who looks through the microscope in the theatre to see if there is anything there - they could be there, immotile etc). My husband said it was like being nackered - best to take a few days/week off work to recover - merely from it being uncomfortable.

We ended up going down the Donor sperm route because they found nothing at all there (due to the meds DH is on and the numerous ops he's had down there).

My advice would be to make an appointment with a FS and go to the next step for a SSC. They will also do blood tests to check for the genetic abnomalities etc.
