The sperm tests the FSs tend to do are more in depth than the ones the GP does. They will probably also set up some 21 day monitoring, to see if you are ovulating.
They may also make you do a Glucose Tolerance Test to see if you have any insulin resistance.
Be prepared to get given lots of information.
Find out as much as you can about Clomid/Metformin/PCOS/Ovulation/Basal Temping/Endo etc before you go so that you don't get overwhelmed at the meeting and you can ask questions.
