Hi sandyallen!
I believe that when you first go to your doctor, he/she will ask you a bunch of questions, and from there, they will send you for blood work (test your hormone levels) and then perhaps even do an ultrasound (check for pcos, etc...) if you have not been trying for at least a year to get prenant, they will not send you to a "fertility specialist". If it has been over a year however (20-30 is a year, 35 & up is 6 months!), you can go to the specialist, and yes, they may also test your husband (sperm count, mobility, etc...)!
At least this is what my own family doctor has told me. I have only been trying for 5 mths, but I am still going to call tomorrow morning and make an app't to see him and discuss what may be going on. Are you experiencing similar problems? (not ovulating, missed periods, etc...)? How long have you been ttc?
Best of luck to you, and baby dust to you and your husband as well!!!!!
