Finally getting somewhere

I've been ttc for nearly a year and still not had any luck, so I decided to go to the doctors to get some answer. I've had some bloods taken and the've came back clear and nothing seems wrong. My partner is having his sperm sent of this Friday so will have to wait 7-10 days for the results. The doctors have now transferred us to the hospital because there no other tests they can do and now I've just got to wait for a letter to come through the post for an appointment. I was wondering what sort of tests will the hospital do?
